GE Aero Package Training Course Introduction SAFETY CONSIDERATIONS

The following are general safety precautions that are not related to any specific procedures and do not appear elsewhere in this manual. Personnel must understand and apply these precautions during all phases of operation and maintenance. Health Hazards Use all cleaning solvents, fuels, oil adhesives, epoxies, and catalysts in a well-ventilated area. Avoid frequent and prolonged inhalation of fumes. Concentrations of fumes of many cleaners, adhesives, and esters are toxic and cause serious adverse health effects, and possible death, if inhaled frequently. Wear protective gloves and wash thoroughly with soap and water as soon as possible after exposure to such materials. Take special precautions to prevent materials from entering the eyes. If exposed, rinse the eyes in an eyebath fountain immediately and report to a physician. Avoid spilling solvents on the skid. Review the hazard information on the appropriate Material Safety Data Sheet and follow all applicable personal protection requirements. Environmental Hazards The disposal of many cleaning solvents, fuels, oils, adhesives, epoxies, and catalysts is regulated and, if mismanaged, could cause environmental damage. Review Material Safety Data Sheets, product bulletin information, and applicable local, state and federal disposal requirements for proper waste management practices.

Fire Hazards Keep all cleaning solvents, oils, esters and adhesives away from exposed-element electric heaters, sparks or flame. Do not smoke when using flammable materials, in the vicinity of flammable materials, or in areas where flammable materials are stored. Provide adequate ventilation to disperse concentrations of potentially explosive fumes or vapors. Provide approved containers for bulk storage of flammable materials, and approved dispensers in the working areas. Keep all containers tightly closed when not in use. Electrical Hazards Use extreme care when working with electricity. Electricity can cause shock, burns or death. Electrical power must be off before connecting or disconnecting electrical connectors. Lethal output voltages are generated by the ignition exciter. Do not energize the exciter unless the output connection is properly isolated. Be sure all leads are connected and the plug is installed. All personnel should be cleared to at least 5 feet before firing the exciter. Compressed Air Hazards Air pressure used in work areas for cleaning or drying operations shall be regulated to 29 psi or less. Use approved personal protective equipment (goggles or face shield) to prevent injury to the eyes. Do not direct the jet of compressed air at yourself or other personnel so that refuse is blown onto adjacent work stations. If additional air pressure is required to dislodge foreign materials from parts, ensure that approved personal protective equipment is worn, and move to an isolated area. Be sure that the increased air pressure is not detrimental or damaging to the parts before applying high-pressure jets of air.

Procedural Hazards Observe all specified and logical safety practices when assembling or disassembling the engine. Wear safety glasses or other appropriate eye protection at all times. Do not allow safety wire or wire clippings to fly from the cutter when removing or installing wire. Do not use fingers as guides when installing parts or checking alignment of holes. Use only correct tools and fixtures. Avoid “shortcuts,” such as using fewer-than-recommended attaching bolts or inferior-grade bolts. Heed all warnings in this manual and in all vendor manuals, to avoid injury to personnel or damage to gas turbine parts.

Tooling Hazards Improperly maintained tools and support equipment can be dangerous to personnel, and can damage gas turbine parts. Observe recommended inspection schedules to avoid unanticipated failures. Use tooling only for its designed purpose and avoid abuse. Be constantly alert for damaged equipment, and initiate appropriate action for approved repair immediately.

Gas Turbine Operational Hazards The outside surfaces of the engine are not insulated; therefore, adequate precautions shall be taken to prevent operating personnel from inadvertently coming into contact with these hot surfaces. The gas turbine is a source of considerable noise. It is necessary for personnel working on the gas turbine or in its vicinity to wear proper ear protection equipment when it is operating. The gas turbine is a high-speed machine. In case of component failure, the skid housing would contain compressor and turbine blade failures, but might not contain major compressor or turbine disk failures. Operating personnel shall not be permanently stationed in or near the plane of the rotating parts. Low-pressure, high-velocity airflow created by the compressor can draw objects or personnel into the engine. Although an inlet screen is used, personnel should not stand in front of the inlet while the engine is operating. When entering the gas turbine enclosure, the following requirements must be met: •The gas turbine will be shut down or limited to core idle power. •The fire extinguishing system will be made inactive. •The enclosure door shall be kept open. If the gas turbine is operating, an observer shall be stationed at the enclosure door, and confined space entry procedures will be followed. •Avoid contact with hot parts, and wear thermally insulated gloves, as necessary. •Hearing protection (double) will be worn if the gas turbine is operating. •Do not remain in the plane of rotation of the starter when motoring the gas turbine. When performing maintenance on electrical components, turn off electrical power to those components, except when power is required to take voltage measurements. Lock out all controls and switches, if possible; otherwise, tag electrical switches “Out of Service” to prevent inadvertent activation. Tag the engine operating controls “Do Not Operate” to prevent the unit from being started during a shutdown condition. F-000-00-00-000-00

Cleanliness and FOD/DOD FOD/DOD (foreign object damage/domestic object damage) is the single major cause of premature gas turbine failure. Prevention is the only practical means of protecting against FOD, and adherence to the following guidelines cannot be over-emphasized. •Empty pockets of all lose objects. •Keep maintenance area clean and organized. •Keep FOD containers in the work area to receive bits of safety wire, used gaskets, Orings and other similar types of debris. USE THEM. •Do not use the gas turbine as a shelf to hold parts and tools during maintenance. •Install protective covers and caps on all exposed openings during maintenance. •Remove protective caps and covers only when required to install a part or make a connection. •After protective caps and covers are removed, inspect all openings and cavities for foreign objects and cleanliness. •After maintenance, thoroughly clean and inspect work area. Account for all tools, parts, and materials used during maintenance.

Turbine Basics

OVERVIEW The major components of the engine are a compressor section, combustion section, and a turbine. The turbine is mechanically coupled and drives the compressor by a drive shaft. The compressor, combustor, and turbine are called the core of the engine, since all gas turbines have these components. The core is also referred to as the gas generator (GG) since the output of the core is hot exhaust gas. The gas is passed through an exhaust duct to atmosphere. On some types of applications, the exhaust gas is used to drive an additional turbine called the power turbine which is connected to a piece of driven equipment (i.e. generators, pumps, process compressors, etc). Because of their high power output and high thermal efficiency, gas turbine engines are also used in a wide variety of applications not related to the aircraft industry. Connecting the main shaft (or power turbine) of the engine to an electromagnet rotor will generate electrical power. Gas turbines can also be used to power ships, trucks and military tanks. In these applications, the main shaft is connected to a gear box.

TURBINE BASICS The balloon drawings above illustrate the basic principles upon which gas turbine engines operate. Compressed inside a balloon, as in (A) above, exerts force upon the confines of the balloon. Air, which has weight and occupies space, by definition, has mass. The mass of the air is proportional to its density, and density is proportional to temperature and pressure. The air mass confined inside the balloon, accelerates from the balloon, creating a force as it is released (B). This force increases as mass and acceleration increase, as stated in Newton’s second law; force equals mass times acceleration (F = MA). The force created by the acceleration of the air mass inside the balloon results in an equal and opposite force that causes the balloon to be propelled in the opposite direction, as stated in Newton’s third law (for every action, there is an equal and opposite reaction). Replacing the air inside the balloon, as in (C) sustains the force and, although impractical, allows a load to be driven by the force of the air mass accelerating across and driving a turbine, as in (D). In (E) a more practical means of sustaining the force of an accelerating air mass used to drive a load is illustrated. A housing contains a fixed volume of air, which is compressed by a motor driven compressor. Acceleration of the compressed air from the housing drives a turbine that is connected to the load. In (F) fuel is injected between the compressor and the turbine to further accelerate the air mass, thus multiplying the force used to drive the load. In (G) the motor is removed and the compressor is powered by a portion of the combustion gas, thus making the engine self-sufficient as long as fuel is provided. In (H) a typical gas turbine-engine operation is represented. Intake air is compressed, mixed with fuel and ignited. The hot gas is expanded across a turbine to provide mechanical power and exhausted to atmosphere.

COMPRESSION – COMBUSTION – EXPANSION – EXHAUST Four processes occur in gas turbine engines, as illustrated above. These processes, first described by George Brayton and called the Brayton cycle, occur in all internal combustion engines. The Brayton steps are as follows: Compression occurs between the intake and the outlet of the compressor (Line A-B). During this process, pressure and temperature of the air increases. Combustion occurs in the combustion chamber where fuel and air are mixed to explosive proportions and ignited. The addition of heat causes a sharp increase in volume (Line BC). Expansion occurs as hot gas accelerates from the combustion chamber. The gases at constant pressure and increased volume enter the turbine and expand through it. The sharp decrease in pressure and temperature (Line C-D). Exhaust occurs at the engine exhaust stack with a large drop in volume and at a constant pressure (Line D-A). The number of stages of compression and the arrangement of turbines that convert the energy of accelerating hot gas into mechanical energy are design variables. However, the basic operation of all gas turbines is the same.

CONVERGENT AND DIVERGENT DUCTS Compressors in gas turbine engines use convergent and divergent ducts to generate the high pressures necessary to (a) provide a “wall of pressure,” preventing expanding hot gas from exiting through the engine inlet, as well as, through the exhaust; and (b) provide the proper ratio of air-to-fuel for efficient combustion and cooling of the combustion chamber. Pressure decreases through convergent ducts and increases through divergent ducts, a phenomenon which is demonstrated in paint spray equipment. Compressed air, forced through a convergent duct, generates a lower pressure through the narrow section to draw in paint. Expansion through a divergent section then increases pressure and air volume, dispersing the paint in an atomized mist.

INLET GUIDE VANES Inlet guide vanes direct, or align, airflow into the first rotating blade section where velocity is increased by the addition of energy. The following stator vane section is divergent, providing an increase in static pressure and a decrease in air velocity. Airflow then enters the second stage at a higher initial velocity and pressure than at the inlet to the preceding stage. Each subsequent stage provides an incremental increase in velocity and static pressure until the desired level of pressure and velocity is reached.

Some compressor stator vanes are designed to move, changing their divergence, allowing regulation of compressor outlet pressure and velocity to achieve the proper ratio of air for fuel combustion and cooling versus engine speed and power output.

COMPRESSORS Compressors in gas turbine engines use convergent and divergent ducts to generate the high pressures necessary to (a) provide a “wall of pressure,” preventing expanding hot gas from exiting through the engine inlet as well as through the exhaust; and (b) provide the proper ratio of air-to-fuel for efficient combustion and cooling of the combustion chamber. Pressure decreases through convergent ducts and increases through divergent ducts, a phenomenon which is demonstrated in paint spray equipment. Compressed air, forced through a convergent duct, generates a lower pressure through the narrow section to draw in paint. Expansion through a divergent section then increases pressure and air volume, dispersing the paint in an atomized mist. All turbine engines have a compressor to increase the pressure of the incoming air before it enters the combustor. Compressor performance has a large influence on total engine performance. There are two main types of compressors: axial and centrifugal. In the illustration, the example on the left is called an axial compressor because the flow through the compressor travels parallel to the axis of rotation. An apparent contradiction in the operation of the axial-flow compressor is that high pressure is generated, although the overall divergent shape would appear to cause a lower output pressure. Output pressure is increased by divergence in each static inter-stage section. Rotating compressor blades between each static stage increases the velocity that is lost by injecting energy. The compressor on the right is called a centrifugal compressor because the flow through this compressor is turned perpendicular to the axis of rotation. Centrifugal compressors, which were used in the first jet engines, are still used on small turbojets and turbo-shaft engines. Modern large turbojet, turbofan, and turbo-shaft engines usually use axial compressors.

COMPRESSOR STALL A stall can happen within the compressor if the air moves from its general direction of motion (also known as the angle of attack). At this point, the low pressure on the upper surface disappears on the stator blade. This phenomenon is known as a stall. As pressure is lost on the upper surface, turbulence created on the backside of the stator blade forms a wall that will lead into the stall. Stall can be provoked if the surface of the compressor blade is not completely even or smooth. A dent in the blade, or a small piece of material on it, can be enough to start the turbulence on the backside of the blade, even if the angle of attack is fairly small. Each stage of compression should develop the same pressure ratio as all other stages. When a stall occurs, the front stages supply too much air for the rear stages to handle, and the rear stage will choke. High Angle of Attack If the angle of attack is too high, the compressor will stall. The airflow over the upper airfoil surface will become turbulent and destroy the pressure zone. This will decrease the compression airflow. Any action that decreases airflow relative to engine speed will increase the angle of attack and increases the tendency to stall. Low Angle of Attack If there is a decrease in the engine speed, the compression ratio will decrease with the lower rotor velocities. With a decrease in compression, the volume of air in the rear of the compressor will be greater. This excess volume of air causes a choking action in the rear of the compressor with a decrease in airflow. This in turn decreases the air velocity in the front of the compressor and increases the tendency to stall.

Turbine Basics

COMBUSTORS All turbine engines have a combustor, in which the fuel is combined with high pressure air and burned. The resulting high temperature exhaust gas is used to turn the turbine and produce thrust when passed through a nozzle. The combustor is located between the compressor and the turbine. The combustor is arranged like an annulus, or a doughnut, as shown by illustrations above. The central shaft that connects the turbine and compressor passes through the center hole. Combustors are made from materials that can withstand the high temperatures of combustion. The liner is often perforated to enhance mixing of the fuel and air. There are three main types of combustors, and all three designs are found in gas turbines: • The combustor at the right is an annular combustor with the liner sitting inside the outer casing which has been peeled open in the drawing. Many modern combustors have an annular design. • The combustor on the left is an older can or tubular design. Each can has both a liner and a casing, and the cans are arranged around the central shaft. • A compromise design (not shown) is a can-annular design, in which the casing is annular and the liner is can-shaped. The advantage to the can-annular design is that the individual cans are more easily designed, tested, and serviced. Turbine blades exist in a much more hostile environment than compressor blades. Located just downstream of the combustor, turbine blades experience flow temperatures of more than a thousand degrees Fahrenheit. Turbine blades must be made of special materials that can withstand the heat, or they must be actively cooled. In active cooling, the nozzles and blades are hollow and cooled by air which is bled off the compressor. The cooling air flows through the blade and out through the small holes on the surface to keep the surface cool.

FLAME-STABILIZING AND GENERAL-FLOW PATTERNS The flame stabilizing and general-flow patterns are illustrated above for a typical “can-type” combustion chamber. Although modern engines use one continuous annular combustion chamber, the can-type simplifies illustration of the cooling and combustion techniques used in all combustion chambers. The temperature of the flame illustrated in the center of the combustor is approximately 3200°F at its tip when the engine is operating at full load. Metals used in combustion chamber construction are not capable of withstanding temperatures in this range; therefore, the design provides airflow passages between the inner and the outer walls of the chamber for cooling and flame shaping. Air flowing into the inner chamber is directed through small holes to shape the flame centering it within the chamber, to prevent its contact with the chamber walls. Approximately 82% of the airflow into combustion chambers is used for cooling and flame shaping; only 18% is used for fuel combustion. Regulation of fuel flow determines engine speed. Stator vane control in the compressor controls pressure and velocity into the combustion chamber as a function of compressor speed.

TURBINE All gas turbine engines have a turbine located downstream of the combustor to extract energy from the hot flow and turn the compressor. Work is done on the turbine by the hot exhaust flow from the combustor. Since the turbine extracts energy from the flow, the pressure decreases across the turbine. The pressure gradient helps keep the boundary layer flow attached to the surface of the turbine blades. Since the boundary layer is less likely to separate on a turbine blade than on a compressor blade, the pressure drop across a single turbine stage can be much greater than the pressure increase across a corresponding compressor stage. A single turbine stage can be used to drive multiple compressor stages. Because of the high pressure change across the turbine, the flow tends to leak around the tips of the blades. The tips of turbine blades are often connected by a thin metal band to keep the flow from leaking. Turbine blades exist in a much more hostile environment than compressor blades. Sitting just downstream of the combustor, the blades experience flow temperatures of more than a thousand degrees Fahrenheit. Turbine blades must be made of special materials that can withstand the heat, or they must be actively cooled. In active cooling, the nozzles and blades are hollow and cooled by air which is bled off the compressor. The cooling air flows through the blade and out through the small holes on the surface to keep the surface cool.

TURBINE (Continued) The compressor drive turbine is an “impulse reaction”-type designed for maximum efficiency in converting hot-gas flow into rotational mechanical energy. A first-stage fixed nozzle directs flow into the first-stage of rotating blades. The impulse of expanding hot gas upon the lower surface of each rotating blade propels motion in the upward direction. Hot gas flow above the following blade creates a lower pressure above the blade as above an aircraft wing, causing additional rotational force. Subsequent stages operate identically, multiplying the rotational force. Compressor and loaddriving turbines consist of a varying number of stages, depending upon the load being driven and other design considerations.

TURBINE SHAFTS The figure above shows the standard gas turbine shaft arrangements. Single shaft illustration is the traditional single shaft assembly. It consists of the axial flow compressor; Turbine and Power Turbine are all mechanically linked. If we add to this shaft the generator and gearbox, we have a shaft system with a high moment of inertia. This is the favored configuration for electrical generation because this provides additional speed (Frequency) stability of the electrical current during large load fluctuations. This configuration is typical of heavy-duty industrial “frame” turbines, such as the MS7001. The twin shaft illustration shows the standard two shaft arrangement with the compressor and turbine only connected, and an unconnected power turbine and output shaft that will rotate independently. This configuration is favored for variable speeddrive packages, such as pumps and compressors, because the gas generator or gas producer can run at its own optimum speed for a given load. The LM2500 utilizes this configuration and has been applied to both electric power generation and a variety of mechanical drive applications. Aircraft jet engines have for many years been adapted for industrial use as shown in the diagrams above. The concentric shaft illustration, above left, shows a more complicated aero-derivative industrial turbine arrangement. This, too, is still essentially a two shaft configuration but the gas generator core (an original jet-engine) was designed with two spools, a Low Pressure Shaft and a High Pressure Shaft. This engine configuration allows the load to be driven from either the exhaust end or the compressor air intake end. This is the configuration used by the LM6000 The concentric shaft with power turbine illustration is essentially a two shaft arrangement with a gas generator originally designed for propulsion. An independently rotating Power Turbine, manufactured especially to match the flow of the jet engine, is added to the gas path as the power/torque producer.

NOx CONTROL Oxides of Nitrogen result from the thermal fixation of molecular nitrogen and oxygen in the combustion air. Its rate of formation is extremely sensitive to local flame temperature and, to a lesser extent, to local oxygen concentrations. Virtually all thermal NOx is formed in the region of the flame at the highest temperature. Maximum thermal NOx production occurs at a slightly lean fuel-to-air ratio due to the excess availability of oxygen for reaction within the hot flame zone. Control of local flame fuel-to-air ratio is critical in achieving reductions in thermal NOx. Combustion Controls Reduction of Nox emissions are accomplished by: • Injection of water or steam at the fuel nozzle in order to reduce combustion temperature • Specially designed Dry Low Emissions (DLE) combustors and fuel systems The injection of water or steam into the flame area of a turbine combustor provides a heat sink, which lowers the flame temperature and thereby reduces thermal NOx formation. Water or steam injection, also referred to as "wet controls," have been applied effectively to both aeroderivative and heavy duty gas turbines, and to all configurations. Reduction efficiencies of 70 to 85+ percent can be achieved with properly controlled water or steam injection, with NOx emissions generally higher for oil-fired turbines than for natural gas-fired units. The most important factor affecting reduction efficiency is the water-to-fuel ratio. In general, NOx reduction increases as the water-to-fuel ratio increases; however, increasing the ratio increases carbon monoxide and, to a lesser extent, hydrocarbon emissions at water-to-fuel ratios less than one. Further, energy efficiency of the turbine decreases with increasing water-to-fuel ratio. Post-Combustion Controls The major type of post-combustion control used in gas turbines is Selective Catalytic Reduction (SCR). Applications use SCR to supplement reductions from steam or water injection, or combustion modifications. Carefully designed SCR systems can achieve NOx reduction efficiencies as high as 90 percent. The Selective Catalytic Reduction (SCR) process reduces NOx emissions by using ammonia in the presence of a catalyst. Vaporized ammonia is injected into the flue gas at the appropriate temperature. The ammonia functions, in the presence of the NOx removal catalyst, as a reducing agent to decompose nitrous oxides NOx in the flue gas into nitrogen gas and water vapor. F-000-00-10-000-00

LM6000 Construction and Operation

The General Electric LM6000 gas turbine is a stationary gas turbine that is derived from the family of CF6 jet engines. The aircraft version of the engine is called the CF6-80C2 turbofan engine and is used to drive several types of “wide body” commercial aircraft, including the Boeing 747-400. The experience and technology of the CF6-80C2 and the well-proven LM2500 have been applied to the LM6000 to make it one of the best engines on the market today. Although the LM6000 gas turbine was developed recently (first application in 1992), General Electric was one of the first developers of the aero-derivative (a gas turbine designed first as a flight engine, then redesigned for industrial use) with more than 30 million running hours. General Electric engines have an availability of 99.6% overall. The LM (Land and Marine) series of gas turbines has the following gas turbines: LM500, LM1500, LM1600, LM2500, LM2500+, LM5000, LM6000 ranging in power output from 14 to 50 megawatts (MW).

The following changes were made to convert the CF6-80C2 to the LM6000: • Front fan removed and inlet guide vanes added • LP compressor from the CF6-50 / LM5000 used • Front and rear frames adapted • Output shafts added to the front of the LPC and the back of the LPT • Bearing 7R added • New industrial fuel system added • Balancing disk added to the LPT • Hydraulic control system for the variable geometry added Since it’s introduction in 1992, the original LM6000PA was followed by introduction of the model PB, the dry low emissions (DLE) version. In 1998, the PC model was introduced and incorporated design changes to the LPC, HPC, LPT, balance piston system and the fuel system. These design changes increased shaft power output by approximately 3.4 MW, and engine efficiency by approximately 2%. The LM6000 PD is the LM6000 PC modified with the Dry Low Emission Combustion System (DLE). This model made its appearance in mid-1998. DLE system requires changes to be made to the fuel nozzles and the annular combustion chamber. F-060-00-10-000-00

The LM6000 gas turbine is a dual-rotor, concentric drive-shaft, gas turbine capable of driving a load from the front and/or rear of the low-pressure (LP) rotor. The main components consist of a variable inlet guide vane (VIGV) assembly or inlet frame assembly, a 5-stage low-pressure compressor (LPC), a 14-stage variable-geometry high-pressure compressor (HPC), an annular combustor, a 2-stage high-pressure turbine (HPT), a 5-stage low-pressure turbine (LPT), an accessory gearbox (AGB) assembly, and accessories. The LP rotor consists of the LPC and the LPT that drives it. Attachment flanges are provided on both the front and the rear of the LP rotor for connection to the packager-supplied power shaft and load. The high-pressure rotor consists of the 14-stage HPC and the 2-stage HPT that drives it. The high-pressure (HP) core consists of the HPC, the combustor, and the HPT. The high- and low-pressure turbines drive the high- and low-pressure compressors through concentric drive shafts.

Air enters the gas turbine at the IGV/VIGVs and passes into the LPC. The LPC compresses the air by a ratio of approximately 2.4:1. Air leaving the LPC is directed into the HPC. Variable bypass valves (VBVs) are arranged in the flow passage between the two compressors to regulate the airflow entering the HPC at idle and at low power. To further control the airflow, the HPC is equipped with variable stator vanes (VSVs). The HPC compresses the air to a ratio of approximately 12:1, resulting in a total compression ratio of 30:1, relative to ambient. From the HPC, the air is directed into the single annular combustor section, where it mixes with the fuel from 30 fuel nozzles. An igniter initially ignites the fuel-air mixture then, once combustion is self-sustaining, the igniter is turned off. The hot gas that results from combustion is directed into the HPT that drives the HPC. This gas further expands through the LPT, which drives the LPC and the output load.

From this vantage point specific areas can be described using their “clock hour” positions, such as “3 o’clock” for the right side and “9 o’clock” for the left side, etc. Various signals measured on the LM6000 gas turbine are called after the so called “engine stations,” which are engine locations, numbered in the direction of airflow, from 0 to 8. Station 0 (zero) is the LP compressor inlet; station 8 is the power turbine exhaust. Typical signal names refer to the stations. Station numbers may be subdivided, using alphabetical character or a decimal as a suffix.

Synthetic lube oil is supplied to the bearings and scavenged out of the sumps by a seven (7) element pump assembly. A single supply element provides lubricating oil to all the bearings and gearboxes. The remaining six elements are utilized to scavenge oil away from the bearing sumps and gearboxes. The sump-A scavenge oil drains to the transfer gearbox (TGB) through the 6:00 o’clock compressor front frame (CFF) strut that houses the radial driveshaft. Oil is then scavenged through the transfer gearbox. The No. 4R/4B and No. 5R bearing zones of the sump-B and sump-C are individually scavenged, as are the No. 6R and No. 7R bearing zones of the D and E sump. All sumps emit oil mist-carrying air that is vented to a packager-supplied air-oil separator.

The gas turbine design uses the dry sump system to provide lubrication to the gas turbine main bearings. The dry sump system employs five subsystems: • Oil Supply - Oil is delivered to the bearings through jets pressurized by a supply pump deliver oil onto the bearings. • Oil Scavenge - Oil scavenge is accomplished when suction, created by the pumping action of a scavenge oil pump, is applied to a port in the lowest point of the oil-wetted cavity. • Seal Pressurization - Bleed air, directed to the sump cavity by ports or tubes in the engine structure, pressurizes seals. • Sump Vent - By venting the oil-wetted cavity out the top to ambient air pressure, a positive flow of pressurizing air to the sump is maintained. • Cavity Drain - Oil leaked from the seals (sump B and sump C) is carried to an overboard dump location.

Bearing Oil Seals When a fault occurs and oil leaks across the oil seals, it must not be allowed to become a fire hazard or to contaminate the customer bleed air. Therefore, a drain is provided to the pressurization chamber. The drainage line is directly connected to an overboard drain port without shutoff so that, whenever the gas turbine is running, there is a flow of air out the drain. Scavenge pumps are connected by tubes to a low drain point in each sump. Whenever the gas turbine is running, the scavenge pumps are working to remove the oil from the sump drains. The Sump design uses pressurized labyrinth type oil seals between the sump housing and the shaft to contain the oil within the sump, and pressurized labyrinth venting seals to maintain pressurizing air separate from the primary gas turbine airflow. The rotating seal provides multiple serrations machined to a knife edge. The stationary shroud portion of the seal provides a surface opposite the knife edges. The seals reduce the leakage from one cavity to the other. Sump pressurizing airflow supply is a volume and pressure great enough to maintain a flow radially inward to the sump cavity across the oil seals and outward to the gas turbine cavity across the air seals. The airflow inward to the sump sweeps with it any oil that may be on the seals keeping the oil contained in the sump. The inflowing air is removed by both the vent system and the scavenge oil system.

The Air Inlet Volute provides for a smooth transition of airflow from the air filter enclosure into the first stage of the low pressure compressor. The volute changes the airflow direction from a vertical to a horizontal flow. The air inlet casing assembly comprises an external casing, approximately rectangular in shape, and forms a circular internal casing to which the low pressure compressor mounts. The generator drive shafts then runs through the center of the volute to the generator.

A flexible joint of Neoprene rubber polymer is fitted between the inlet volute and the enclosure air ducting to accommodate relative movements. A trash screen (FOD screen) is also included for additional protection against debris in the inlet system.

Mounted on the forward end (ALF) of the inlet volute are the online and offline water wash manifolds. The LP SPRINT manifold is mounted on the rear (ALF) of the volute. Located on the bottom of the volute is a drain line with check valve that is plumbed to the customer provided waste fluid tank.

3.4.2 INLET GUIDE VANE ASSEMBLY The air intake section is designed to interface with a radial inlet duct, which allows inlet air to be drawn from the side or top or with an axial inlet system, which draws air from the front. The radial inlet duct is compatible with either forward or rear drive installations, while the axial inlet can be used only in rear drive installations.

The Optional Variable Inlet Guide Vane Assembly (VIGV) is located at the front of the LPC. It allows flow modulation at partial power, resulting in increased engine efficiency. The VIGV system consists of 43 stationary, leading-edge vanes and variable trailing flaps. The variable flaps can be rotated from 10 degrees open to +60 degrees closed by means of an actuation ring, which is driven by twin hydraulic actuators at the 3 o’clock and 9 o’clock positions. Both actuators are equipped with linear variabledifferential transformers (LVDTs).

Normal engine operation is approximately 5 degrees open (full power) to +35 degrees closed (idle power). The flaps will also close during large power reductions in order to quickly reduce the LPC flow rate and maintain the LPC stall margin. The packager-supplied control is designed to provide excitation and signal conditioning for both LVDTs. It also controls VIGV position by means of closed-loop scheduling of the VIGV actuator position, based on LPC inlet temperature (T2) and HPC discharge static pressure (PS3) corrected to gas turbine inlet pressure conditions (P0).

The VIGV system improves performance for both simple cycle and heatrecovery cycles. It also helps minimize the variable bypass valve (VBV) flow and pressure levels, thereby reducing associated flow noise. A pressurized rotating seal between the VIGV hub and the LPC rotor prevents ingestion of unfiltered air into the flow path. The LM6000 PC engine can be provided with or without the VIGV assembly. LM6000 PC models without a VIGV assembly have a 43-strut inlet frame.

HPC STATOR The HPC stator consists of a cast stator case that contains the compressor stator vanes. The inlet guide vanes and the stages 1–5 vanes can be rotated about the axis of their mounting trunnions to vary the pitch of the airfoils in the compressor flow path. Vane airfoils in the remaining stages are stationary. All fixed and variable vanes are non-interchangeable with other stages to prevent incorrect assembly. The casing is split along the horizontal split-line for ease of assembly and maintenance. The inlet guide vanes and the stages 1 and 2 vane shrouds also support interstage rotor seals. The shrouds are designed to allow the removal of either half of the compressor casing. There are 14 axial stations provided for borescope inspection of blades and vanes.

VARIABLE STATOR VANE ASSEMBLY The VSV assembly, an integral part of the HPC stator, consists of two VSV actuators and levers, actuation rings, and linkages for each VSV stage. Stator vane position is vital to stable, efficient operation of the engine. While the HPC is designed for peak aerodynamic efficiency at full power and full speed, it must also operate at lower speeds. At these lower speeds, the later stages of the compressor cannot consume all the air delivered by the earlier stages. The variable stators accommodate this situation by limiting the compression ratio of the first six stages of the compressor at low speeds and changing the compression at higher speeds. This is accomplished with two hydraulic actuators, one at the 3:00 o’clock position and one at the 9:00 o’clock position. Each actuator uses an LVDT for position feedback to the control system. The control system is designed to provide excitation and signal conditioning for both LVDTs, and to control VSV position by means of closed-loop scheduling of VSV actuator position, based on corrected HP rotor speed (XN2.5R) and inlet temperature (T2.5).

Compressor Rear Frame Assembly The compressor rear frame (CRF) assembly connects the compressor-casing flange to the high-pressure turbine nozzle assembly and consists of an outer case, 10 struts, and the B- and C-sump housings. The outer case supports the combustor, fuel manifolds and fuel nozzles, two ultraviolet flame detectors for flame sensing, an accelerometer, discharge static (P3) and HPC discharge temperature sensor (T3). The hub provides support for a thrust bearing (4B) and two roller bearings (4R and 5R) to support the midsection of the HP rotor system.

Bearing axial and radial loads, and a portion of the first-stage nozzle load, are transmitted through the hub and 10 radial struts to the case. The hub, struts, and outer casing are a one-piece casting. The casting is welded to the fuel embossment ring and bolted to the aft case. This serves as the structural load path between the compressor casing and the HPT stator case. Seven borescope ports are provided for inspection of the combustor, pre-mixers, and HPT. B-sump and C-sump service lines are contained in, and pass through, the CRF struts.

Combustor Assembly The LM6000 gas turbine uses a singular annular combustor and is furnished with 30 externally mounted fuel nozzles for liquid distillate fuel, natural gas fuel, or dual fuel, depending upon the fuel system specified by the customer. Fuel systems may also be equipped for water or steam injection for NOx suppression. This combustion system is a high-performance design that has consistently demonstrated low exit temperature pattern factors, low-pressure loss, low smoke, and high combustion efficiency at all operating conditions.

SINGULAR ANNULAR COMBUSTOR Key features of the singular annular combustor are the rolled-ring inner and outer liners; the low-smoke emission, swirl-cup dome design and the short burning length. The short burning length reduces liner cooling air consumption, which improves the exit temperature pattern factor and profile. The swirl-cup dome design serves to leanout the fuel-air mixture in the primary zone of the combustor. This eliminates the formation of the high-carbon visible smoke that can result from over-rich burning in this zone.

DOME The dome is a fabricated component consisting of 30 vortex inducing swirl assemblies consisting of two counter-rotating primary and secondary swirlers. Their purpose is to provide flame stabilization and complete mixing of the fuel air mixture. The primary swirler floats on the face of the secondary swirler to allow growth difference for the fuel nozzles. The entire surface of the dome is swept by a film of cooling air.

LINERS The inner and outer liners are composed of a series of circumferentially rolled ring strips joined together by resistance welding. They are protected from convective and radiant heat by continuous circumferential film cooling. Combustion zone dilution and mixing air entry is provided by a pattern of various sized circular holes in each ring. These holes provide recirculation for flame stabilization and shape the exit gas profile. Ports and tube assemblies have been located at the 3:00 and 5:00 o'clock positions for the igniter plugs. The liners and dome have a thermal barrier coating applied to the hot side.

IGNITION SYSTEM The ignition system produces the high-energy sparks that ignite the fuel-air mixture in the combustor during starting. The system consists of high-energy spark igniters, a high-energy capacitor-discharge ignition exciter, and an interconnecting cable. The ignition cables interconnect directly between the package-mounted exciters and the igniters, which are mounted on the engine compressor rear frame. During the start sequence, fuel is ignited by the igniter, which is energized by the ignition exciter. Once combustion becomes self-sustaining, the igniter is de-energized at ≥ 400 F (204 C).

Proper installation of the igniter plug on the combustion chamber is essential for long operating life. The igniter plug has a special distance (packing) ring that must be installed between the plug and compressor rear frame. The correct distance of the plug in the rear frame is important, both for operation and cooling, and it can be adjusted with the distance ring. Cooling is achieved with compressor air flowing alongside the igniter plug tip. Also, 12 holes in the plug tip are present for cooling purposes and, finally, 6 holes provide cooling air for the igniter plug shank.

The ignition system is normally energized only during the starting sequence. However, the circuit should be arranged so that the ignition system can be manually operated for maintenance and testing.

To ensure a successful light off, the ignition system is comprised of two independent ignition systems. Due to already increased air temperature from compression through the compressor, and fuel atomization from the fuel nozzle, it is possible to achieve ignition with only one igniter. Running two independent systems ensures the ability to maintain normal operations even with the complete loss of one system. Because of this configuration it is necessary to check the operation of the igniter system on a routine basis in accordance with the maintenance work package.

Typically the igniters should be checked when a turbine fails to light-off and all other primary start requirements are met. Such as: •Proper acceleration of the HPC (XN2.5) •Proper CDP pressure (P3) •Proper fuel valve Position This type of failure is due to loss of both igniters. The only igniter indication that the operator can monitor is the logic state change on the Turbine Overview Screen. The operator screen change is a function of an energized relay coil. If there is a failure in the ignition system, the screen may indicate proper operation but, in reality, the system is inoperable. Because of the high voltage generated by the exciter module, there is no feedback of the igniter output to give a true indication of proper operation of the circuit. Duty cycle is: 90 seconds ON max, 2 start cycles in a 30 minute period Power input is: 106-124 volt AC, Requirement at 60 Hz or 50 Hz

HPT ROTOR The HPT rotor assembly consists of the stage 1 disk and integral shaft, a conical impeller spacer with cover, a thermal shield and a stage-2 disk. Forward and aft rotating air seals are assembled to the HPT rotor and provide air-cooled cavities around the rotor system. An integral coupling nut and pressure tube is used to form and seal the internal cavity. The rotor disks and blades are cooled by a continuous flow of compressor discharge air. This air is directed to the internal cavity of the rotor through diffuser vanes that are part of the forward seal system.

The stage 1 disk/shaft design combines the rotor forward shaft and stage 1 disk into a one-piece unit. Torque is transmitted to the compressor rotor through an internal spline at the forward end of the disk/shaft. The stage 1 blades fit into axial dovetail slots in the disk. The stage 2 disk incorporates a flange on the forward side for transmitting torque to the stage 1 disk. An aft flange supports the aft air seal and the integral coupling nut and pressure tube. Stage 2 blades fit into axial dovetail slots in the disk.

Internally cooled turbine blades are used in both stages. Both stages of blades are cooled by compressor discharge air flowing through the blade shank into the airfoil. The cone-shaped impeller spacer serves as the structural support between the turbine disks. The spacer also transmits torque from the stage 2 disk to the stage 1 disk. The catenary-shaped thermal shield forms the outer portion of the turbine rotor cooling air cavity and serves as the rotating portion of the interstage gas path seal.

Stage 1 HPT Nozzle—The stage 1 HPT nozzle consists of 23 two-vane segments bolted to a nozzle support attached to the hub of the CRF.

High-Pressure Turbine Blade Cooling Stage 1 High-Pressure Turbine Blades—First-stage turbine blades, contained within the CRF, are internally cooled with HPC discharge air. The HPC discharge air is directed through the turbine disk to the blade roots, passing through inlet holes in the shank to serpentine passages within the airfoil section of the blade. This air finally exits through nose and gill holes in the leading edge of the blades, where it forms an insulating film over the airfoil surface through holes in the cap at the outer end of the blade and through holes in the trailing edge of the airfoil.

Stage 2 High-Pressure Turbine Blades—Because the hot-gas path stream is cooler when it reaches the second-stage turbine blades, the cooling required to maintain a suitable metal temperature is not as great as with the first stage. The second-stage blades are, therefore, only cooled by convection. The air moves through passages within the airfoil section and is discharged only at the blade tips.

Forward axial loads are applied by varying air pressure in the balance piston air cavity to maintain thrust loads within the capability of the bearing.

The balance piston system consists of the balance piston disk, the balance piston casing, their associated seals, and the dome-shaped cavity formed by these parts. This cavity is pressurized by stage 11 HPC bleed air. The balance piston casing is attached to the aft-inner hub of the TRF; the balance piston disk is attached to the LPT shaft.

LM6000 Construction and Operation

ENGINE AIRFLOW Air enters the engine at the inlet of the variable inlet guide vanes (VIGVs) and passes into the low-pressure compressor (LPC). The low-pressure compressor compresses the air by a ratio of approximately 2.4:1. Air leaving the low-pressure compressor is directed into the high-pressure compressor (HPC) and is regulated at idle and low power by variable bypass valves (VBVs) arranged in the flow passage between the two compressors. The airflow in the 14-stage HPC is regulated by VIGVs and five stages of variable stator vanes (VSVs). The HPC compression ratio is approximately 12:1. HPC discharge and stage 8 bleed air are extracted, as necessary, for emissions control. Compressor discharge air is then directed to the combustor section. Air entering the combustor is mixed with the fuel and ignited. Once combustion becomes self-sustaining, the igniter is de-energized. The combustion gases then exit to the high-pressure turbine (HPT). The hot gases from combustion are then directed into the HPT, which drives HPC. The exhaust gases exit the HPT and enter the low-pressure turbine (LPT), which drives both the LPC and the output load. The exhaust gases pass through the LPT and exit through the exhaust duct. F-060-00-10-000-00

FLAME SENSORS An ultraviolet flame sensor detects the presence or loss of flame in the engine combustion system for control system logic use in sequencing and monitoring.

The flame sensor hardware consists of two ultraviolet sensor assemblies and two flame-viewing window assemblies, mounted on two holes in the compressor rear frame. The flame sensors come equipped with integral leads, which are connected directly to the packager-supplied signal conditioner.

When turbine speed drops below a defined threshold (Control Constant), the Flame Sensor Reference Shutdown (FSRSD) ramps to a blowout of one flame detector. The sequencing logic remembers which flame detectors were functional when the breaker opened. When any of the functional flame detectors senses a loss of flame, speed decreases at a higher rate until flame-out occurs, after which fuel flow is stopped. Fired shutdown is an improvement over the former fuel shutoff at dropout. By maintaining flame down to a lower speed, there is significant reduction in the strain developed on the hot gas path parts at the time of fuel shut off.

Noise Control The enclosure and air inlet silencer reduce the average near field noise to 85 dB at three feet (1.0 m) from the enclosure and five feet (1.5 m) above grade. Far-field noise levels will be determined by the design of the heat recovery system or exhaust silencer. For most applications the steady-state noise levels emanating from one standard LM6000 60 Hz generator package at 400 feet (122 m) will comply with 59 dB. Lower noise limits can be provided with optional silencing equipment. Noise control will depend on the scope of the equipment supplied, the site plan, and project specific requirements. Noise control may be selected either to meet current noise requirements, or at a level to allow for future site expansion. F-060-00-20-000-00

System Overview

The Turbine Lube Oil System is shown in detail on F&ID XXX244. Please refer to the latest revision of this drawing for correct, site-specific configuration and settings.

The LM6000 gas turbine uses synthetic lube oil (MIL-23699, Mobil Jet Oil II, Exxon Turbo Oil 2380, Castrol 5000) to:

Ø

Lubricate and cool turbine bearing and gearboxes

Ø

Provide oil to the variable geometry control system.

Ø

Lubricate the over-running clutch for the hydraulic starter motor

The LM6000 lube oil system has two distinct sub-systems; a pressurized supply system and a separate scavenge system. Each subsystem has its own filtration.

A multi-element lube oil pump, containing both a supply (one (1)) element and scavenges elements (six (6)) elements, circulates oil through the system. A reservoir, lube oil coolers, piping, valves, and instrumentation complete the system.

TURBINE SUPPLY LUBE OIL SYSTEM The turbine lube oil pump is mounted on the right rear side of the accessory gearbox. The supply element takes suction from the 150-gallon (568 liters) stainless steel turbine lube oil reservoir mounted on the auxiliary skid. Discharge pressure from the supply element is piped to the duplex supply lube oil filters, rated at six (6) microns. Two-way selector valves allow either filter to be on-line while the other is being serviced. From the supply lube oil filters the lube oil is piped to the turbine supply header to lubricate bearings, gearboxes and the hydraulic starter clutch. TURBINE SCAVENGE OIL SYSTEM After the oil is supplied to the gearboxes or bearing sumps, the oil is recovered from the gearboxes and sumps by one of six scavenge elements of the oil pump. Scavenged oil from “A/TGB and B” sumps passes over magnetic chip detectors. The collective oil discharged from all the scavenge elements also passes over a common magnetic chip detector. The oil then flows past a pressure relief valve which lifts when excess oil pressure is sensed, returning excess oil directly to the reservoir. The primary oil flow is then routed to the scavenge filters, where it is filtered to 6 microns. Then the oil flows to the turbine lube oil coolers, where the hot oil is cooled before being returned to the reservoir. A temperature control valve on the cooler discharge bypasses oil around the oil coolers when the oil temperature is below the setpoint. As the oil temperature increases, the temperature control valve starts mixing the warmer oil with cooler oil from the coolers to maintain a preset temperature. After passing through the temperature control valve, the oil is then returned to the reservoir Each engine bearing sump is provided with a sump vent line which allows sump pressurization air and entrained oil to be routed to an air/oil separator. The air/oil separator is mounted on the enclosure roof. By use of a dual-staged filter media and a fin/fan cooler, the separator removes entrained oil from the vent air. Oil is then returned to the reservoir and the vent pressurization air is released to atmosphere.

Bearings And Gearboxes Bearings are classified into two broad categories; friction, also commonly known as plain or Babbitt type, and anti-friction, which contain rollers or balls that makes a rolling contact with the shaft. The gas turbine utilizes anti-friction type bearings, whereas the generator has friction type bearings. Bearings have the following functions. They… •support the load on the shaft. The load may be a gear or the shaft itself. •reduce friction created by turning. This is accomplished both by design and by lubrication and is one of the most important functions of bearings. •reduce friction created by thrust. A specially designed bearing is required for this purpose. •hold a shaft in rigid alignment. A high speed-rotating shaft has a tendency to “whip” unless adequately supported by bearings. A pressure header provides lube oil to each of the bearings to lubricate and cool them. The roller bearings support the radial loads of the shafts, while the ball bearings absorb the shaft’s axial and radial loads. The pressure header also provides oil to lubricate and cool the inlet gearbox, transfer gearbox, and the accessory gearbox. As the oil drains through the bearing and gearboxes, it collects in sumps. Each sump is drained by a scavenge pump that suctions the oil from the bottom of the sumps.

Turbine Engine Dry Sump All sumps are pressurized by low-pressure compressor (LPC) discharge static air pressure (P25). The airflow is of sufficient volume and pressure to maintain a positive airflow inward across the inner seals to the inner sump cavity. This positive airflow carries with it any oil on the seals, thus retaining the oil within the inner cavity. Sump pressurization air enters the outer sump cavity through a pressurizing port. This air then passes across the oil seals into the inner sump cavity, where it is vented to the air-oil separator. Sump pressurization air also passes outward across the outer seals to the engine cavity.

The lube oil is then scavenged out of the bearing sumps and the gearboxes by one of six scavenge oil pump elements of the lube oil supply and scavenge pump. Each of the six scavenge lines are equipped with resistance thermal devices (RTD) to measure scavenge oil temperature after leaving the bearing housing. The RTD’s allow for operator monitoring, alarming and shutdown of the turbine if temperature setpoints are met. Oil from sumps “A/TGB” and “B” is passed over two of three magnetic chip detectors. The third is located in the common discharge line from all scavenge oil pumps. The magnetic chip detectors detect ferrous (of or containing iron) particulate metal in the scavenge oil flow from the bearings & gearboxes. This collection of metal is usually caused by degradation of the bearings or gears in the engine. The chip detectors normally read 300 ohms when clean. As particulate matter collects on the magnet, the resistance reading gets lower. At 100 ohms an alarm is sounded at the control console.

Temperature Control Valve The temperature control valve regulates lube oil return temperature by bypassing some of the hot oil around the lube oil cooler and mixing it with the cool oil from the oil cooler. The thermostatic valve is a fully automatic, 3-way fluid temperature controller for mixing application. Temperature is sensed at port “A” (valve outlet). Port “B” remains fully open until oil temperature reaches approximately 100 °F (38 °C) to 102 °F (39 °C). As the oil, temperature continues to rise port “B” starts to close off and port “C” starts to open, mixing the hot and cool oils. Port “B” is fully closed and port “C” is fully open if oil temperature reaches 116 °F (47 °C) to 118 °F (48 °C). The valve continually modulates the oil flow, maintaining a nominal oil temperature of 110° F (43 °C). The oil is then returned to the lube oil reservoir. F-060-00-20-100-00

LUBE OIL COOLERS

As discussed previously, the lube oil is returned to the reservoir after passing through or bypassing the lube oil cooler, as determined by the three-way thermostatically controlled valve. The lube oil cooler utilizes the principles of conduction, convection or radiation in order to transfer heat from the lube oil to a medium, typically air, water or some other fluid, depending on cooler design. Lube oil coolers employed in the Gas Turbine Generator application are typically one of three basic designs. They are:

•Fin Fan Coolers (Ambient air cooled) •Shell and Tube (water cooled) •Plate Type (Fluid cooled)

Fin Fan Cooler The “fin fan” cooler is a heat-exchanger that uses air as the cooling medium. Oil is passed through the inner tubes of the cooler, and air is forced across the outside of the tubes to decrease the temperature of the circulating oil. The fin fan heat exchanger is a radiator-type heat exchanger that uses electric fans to force air through the radiator, thereby cooling the lubricating oil. After oil passes through the heat exchanger, it is routed directly to the lube oil reservoir. During cold startups, oil may be bypassed around the fin fan heat exchanger if the thermostatic control valve determines the temperature to be lower than the set point. During normal operation, the temperature control valve regulates lube oil return temperature by bypassing some of the hot oil around the lube oil heat exchanger and mixing it with the cool oil from the oil cooler. The thermostatic valve is a fully automatic, three-way fluid temperature controller for mixing application. The valve continually modulates the oil flow, maintaining a nominal oil temperature.

Shell and Tube Type Cooler Shell-and-tube coolers serve to cool the lubricating oil. The shell-and-tube cooler consists principally of a bundle (also called a bank or nest) of tubes encased in a shell. The cooling liquid generally flows through the tubes. The liquid to be cooled enters the shell at one end, is directed to pass over the tubes by baffles, and is discharged at the opposite end of the shell. In other coolers of this type, the cooling liquid flows through the shell and around the tubes; the liquid to be cooled passes through the tubes. The tubes of the cooler are attached to the tube sheets at each end of the shell. This arrangement forms a tube bundle that can be removed as a unit from the shell. The ends of the tubes are expanded to fit tightly into the holes in the tube sheets; they are flared at their outer edges to prevent leakage. One tube sheet and a bonnet are bolted to the flange of the shell. This sheet is referred to as the stationary-end tube sheet. The tube sheet at the opposite end floats in the shell, a design that allows for expansion of the tube bundle. Packing rings, which prevent leakage past the floating-end tube sheet, are fitted at the floating end between the shell flange and the bonnet. The packing joint allows for expansion and prevents the mixing of the cooling liquid with the liquid to be cooled in-side the shell by means of a leak-off, or lantern, gland that is vented to the atmosphere. Transverse baffles are arranged around the tube bundle in such a manner that the liquid is directed from side to side as it flows around the tubes and through the shell. The deflection of the liquid ensures the maximum cooling effect. Several of the baffles serve as supports for the bank of tubes. These baffles are of heavier construction than those that only deflect the liquid.

Plate Heat Exchangers Plate heat exchangers use a number of gasketed metal plates that are compressed together. The plates are designed to allow transfer of heat from one circulating fluid to another. Cooling water enters and flows through one plate, while lube oil flows through the next. Inside the heat exchanger, plates are arranged to provide alternate hot and cold sections, thereby sandwiching the hot lube oil plates between two cold water plates and allowing maximum heat transfer. As oil and water flows through the plates, the large surface area allows heat to be transferred from the hot lube oil to the cooler circulating water. Plate heat exchangers are more efficient than conventional shell and tube heat exchangers because they provide more surface area for better heat transfer. In addition they are smaller in size, require less water, and can operate at higher pressures than comparable shell and tube heat exchangers.

Air / Oil Separator

Bearing sump vent air goes to an air/oil separator located on the roof of the enclosure. The air/oil separator is a two-stage design with a heat exchanger between the stages. The vent air flows through the first separator, which has a filter pad that collects most of the oil mist trapped in the vent air. The vent air then goes through an air-to-vent air heat exchanger, followed by the second stage of oil separation passing through a filter pad in the second separator chamber. Collected oil is returned to the turbine lube oil reservoir and the air is discharged to atmosphere.

Turbine External Lube Oil Operation Lubricating oil is drawn from the turbine lube oil reservoir into the supply pump suction at turbine connector áL1ñ. The supply pump discharges pressurized oil through turbine connector áL6ñ to the duplex filter assembly (lube oil supply filter), removing particles ³ 6 µ, absolute, from the oil. Some filtered oil is taken to the supply valve actuator in the turbine hydraulic system, but most of the filtered supply oil is returned to the turbine at connector áL3ñ. The turbine supply oil pressure is monitored by instruments on the turbine gauge panel. Pressure switches respond according to oil pressure and transmit switch closures to the turbine control system. The control system evaluates information relative to speed and initiates action accordingly. Oil supply pressure gauge PI-6108 indicates supply pressure at the turbine oil header, and pressure transmitter PT-6121 transmits this information to the TCP. Pressure switch PSLL-6115 opens when turbine header oil pressures £ 15 psig (103 kPag)On startup, if PSLL-6115 has not closed when the turbine speed reaches 7800 rpm, the control system initiates a low-oil pressure, fast stop lock out (FSLO) shutdown. Pressure switch PSLL6116 is open at turbine header oil pressures £ 6 psig (41 kPag). On startup, if PSLL-6116 has not closed when the turbine speed is  4500 rpm but  7800 rpm, the control system initiates an FSLO shutdown. Some filtered supply oil from the turbine oil header at turbine connector L3 is used by turbine VG hydraulic pump to operate the turbine VG system. A filter, integral to the VG system, filters pump output. The condition of this filter is displayed by pressure gauge PDI-6149 and monitored by pressure differential switch PDSH-6146. Most oil supplied to turbine oil header at connector L3 is used to lubricate and cool turbine bearings. The turbine scavenge pump scavenges lubrication oil mixed with air from turbine bearings and discharges the air-oil mixture to the external lube oil system via turbine scavenge oil discharge connector L2. The turbine scavenge oil header pressure at L5 is monitored by instruments on the turbine gauge panel. Scavenge oil pressure gauge PI-6109 indicates scavenge oil pressure at scavenge oil pump discharge. Pressure transmitter PT-6122 senses pressure at the scavenge oil pump discharge and transmits that information to the control system. Pressure switch PSH-6117 opens to notify the control system of high scavenge oil back pressure (when pressure at the turbine oil header is  100 psig (689 kPag)). At switch opening, the control system initiates an alarm. A check valve in the filter line prevents oil from the scavenge discharge from draining back into the turbine. Pressure-relief valve PSV-6103 limits scavenge back pressure to 140 psig (965 kPag). F-060-00-20-100-00

The turbine scavenge oil header pressure at L5 is monitored by instruments on the turbine gauge panel.

At switch opening, the control system initiates an alarm. A check valve in the filter line prevents oil from the scavenge discharge from draining back into the turbine. Pressure-relief valve PSV-6103 limits scavenge back pressure to 140 psig (965 kPag). The scavenge oil pump discharge at scavenge oil discharge connector L2is routed to the scavenge oil filter assembly and is filtered through a selected duplex element. Filtered scavenge oil is then cooled by a selected cooler in the heat exchanger before being returned to the reservoir for recirculation. The portion of oil actually routed through the selected cooler is determined by three-way, thermostatic valve TCV6101. This valve apportions oil flow through the selected cooler, as required, to maintain the outlet temperature at 110 °F (43.3 °C). All oil below 110 °F (43.3 °C) is bypassed directly to the lube oil reservoir. Bearing sumps are vented through the air-oil pre-separator, the air-air heat exchanger, and the air-oil separator. The air-oil separator system removes entrained vent air from the lube oil. The oil is returned to the reservoir. Seal/sump oil drains are always open and should have no flow during normal operation. Customer instrument air connector [55] provides air to the LPT at connectors A23, A24, A25, and A28 for air purge cooling after shutdown. The air pressure regulator maintains the purged air pressure at 30 psig (207 kPag).

Turbine External Lube Oil Features The external lube oil system equipment consists of several major assemblies plus interconnects piping and related monitoring instruments. The equipment components are located on the turbine-generator skid and the auxiliary skid. Thermometers are mounted at appropriate points in the piping and oriented for direct observation. Pressure gauges, mounted on one of two gauge panels, directly indicate operating pressures while pressure switches and transmitters, mounted on the same panels, input the pressure information to the control system. Manually operated ball valves throughout the piping facilitate component maintenance. The external lube oil system components on the turbine-generator skid consist of system piping and instrumentation to monitor the turbine oil pressures at the turbine inlet and outlet connectors. The external lube oil system components on the auxiliary skid consist of piping and valving, instrumentation to monitor filter condition, oil reservoir, filter assembly, scavenge oil filter assembly, heat exchangers, and oil tank flame arrestor and demister. Turbine Lube Oil Reservoir The turbine lube oil reservoir is a 150-gallon tank containing synthetic oil on the auxiliary skid. The reservoir is filled via a fill cap and basket strainer, and may be drained via a 2-inch drain valve. An air-oil separator allows air to escape to the atmosphere while capturing the oil droplets to be drained back into the reservoir. A demister/flame arrestor inhibits combustion of flammable vapors. The relief vent cracks open at 1–4 psid (7-28 kPag). Lubricating oil is drawn from the reservoir through a supply shutoff valve. Level gauge LG-6105, located on the side of the tank, provides for direct observation of the oil level in the tank. Tank heater HE-6104 warms lubrication oil during cold-weather operation. Thermostatic control switch TC-6131 energizes the heater whenever the turbine lube oil temperature drops to 90 °F (32 °C). Alarm switch LSL-6102 signals the control system if the oil level drops 12 inches (30 cent.) below the flange while simultaneously de-energizing HE-6104. Thermometer TI-6110, located on the lube oil tank, indicates actual oil temperature in the range of 50–400 °F (10-204 °C). Low oil temperature switch TSL-6113 signals the control system when the oil temperature drops to 70 °F (21 °C).

Turbine Lube Oil Duplex Filters The lube oil supply and scavenge oil filter assemblies are located on the auxiliary skid. Except for external instrumentation, the two assemblies are identical. Each is a duplex, full-flow assembly, with two steel filter shells and replaceable 6-µ-absolute filter elements. A manual shuttle valve may be used to divert oil flow through one element, allowing the other element to be serviced without interruption of operation. For each duplex filter, a differential pressure gauge and two differential pressure switches, located on the auxiliary skid gauge panel and JB-55, warn operating personnel of dirty filter elements. The instruments may be isolated from the system by means of instrument valves while a differential pressure balance valve permits equalizing pressure across the instruments. The lubricating oil system contains three instruments for monitoring operation at the supply and scavenge duplex filter assemblies: (1) differential pressure gauges PDI 6106 and PDI 6107 indicate filter differential pressure in the range of 0–30 psid (0-207 kPad), (2) differential pressure switches PDSH 6120 and PDSH 6118 signal the control system to initiate an alarm if the pressure drop across the oil filter rises to 20 psid (138 kPad), and (3) differential pressure switches PDSHH 6144 and PDSHH 6119 signal the control system to initiate a cool-down lockout (CDLO) shutdown if the pressure drop across the oil filter rises to 25 psid (172 kPad). Turbine Lube Oil Heat Exchangers The shell and tube heat exchanger assembly is located on the auxiliary skid. The lube oil may bypass the coolers if thermostatic control valve TCV-6101 determines the temperature to be < 110 °F (430 °C). After the lube oil passes through control valve TCV-6101, temperature indicator TI-6137 measures actual lube oil temperature. This indicator is scaled 0-250 °F (0-121 °C). The lube oil is then routed directly to the reservoir.

Air-Oil Separator The turbine air-oil pre-separator, air-air heat exchanger, and the air-oil separator are located on the roof of the turbine enclosure and vent to the atmosphere. Turbine engine sumps A/B and C, at engine connector áA9ñ, are connected to the separator via a 6-inch line. Sumps D and E, at engine connector áA10ñ, are also connected to the separator via a 6-inch (15 cent.) line. The pre-separated oil is drained to the turbine lube oil tank via a 1½-inch (3.8 cent) line, the air is vented to the air-air heat exchanger where it is cooled, and then, the air is vented to the air-oil separator. The separated oil is drained to the turbine lube oil tank via a trapped ½-inch (1.3 cent.) line, and the air is vented to the atmosphere. A sight gauge allows operating personnel to observe oil flow from the pre-separator to the lube oil tank. Pressure switch PDSH6148 indicates excessive differential pressure and initiates alarm PDAH-6148 if pressures increase to ³ 1.75 psid (12 kPad).

VG System Operation The VG hydraulic pump is a fixed-displacement pump which supplies pressurized lube oil to the HCU for delivery to the actuators. Positioning of the VIGVs, VSVs and VBVs is scheduled by the Millennium or Netcon Control System (provided with the unit). Electrical inputs to separate servo valves in the HCU, which is mounted on the VG hydraulic pump, position the servo valves in the correct position. Position feedback to the control system is provided by Linear Variable Differential Transformers (LVDTs) integral to the individual system actuators.

Hydraulic Control Unit

The HCU controls the hydraulic pressure for the servo system. The HCU receives oil from the VGC pump. This oil is filtered in a single filter (for safety reasons only, since the oil has already passed the lube oil filter). From the filter the oil flows to two control valves, one adjusted to 83 bar for the VBV system via the internal connections in the HCU and VGC pump. The HCU contains three servo valves, for the IGV, VBV and VSV control system. The other servo systems operate with servo valves that are incorporated in the control valve assemblies. The servo valves in the HCU operate on DC signal with the following characteristics: •Null bias current

20+/- 2 mA

•Normal current in coil

Variable Bypass Valve (VBV) System

The VBV system is located on the compressor front frame assembly. It is used to vent LPC discharge air overboard through the LPC bleed air collector, in order to maintain LPC stall margin during starting, partial power operation, and large power transients. The VBV system consists of 12 variable-position bypass valves, six VBV actuators (two with LVDTs), six actuator bellcranks, 12 VBV bellcranks, and an actuation ring. The actuators are located at the 1:00, 3:00, 5:00, 7:00, 9:00, and 11:00 o’clock positions on the compressor front frame. The six actuators are positioned with one VBV on each side of each actuator. The actuators, actuation ring and VBVs are mechanically linked by bellcranks and pushrods. The actuators position the actuation ring, which opens and closes the VBVs. The 5:00 and 11:00 o’clock actuators are equipped with integral LVDTs for position indication. The Millennium Control System is designed to control VBV position by means of closed-loop scheduling of VBV actuator position, based on LPC inlet temperature (T2) and high pressure (HP) rotor speed corrected to inlet conditions (XN25R2).

Variable Stator Vane (VSV) System The VSV system consists of two VSV actuators and levers, actuation rings, and linkages for each VSV stage. The VSV system has two hydraulic actuators, located at the 3:00 and 9:00 o’clock positions. Each actuator is equipped with an integral LVDT for position feedback. The Millennium Control System controls VSV position by means of closed-loop scheduling of VSV actuator position, based on corrected high-pressure (HP) rotor speed (XN25R). The VSV system has a number of natural wear points that must be inspected on a regular basis. By keeping the system in good physical condition, accurate positioning of the vanes is possible. Misadjusted or worn vanes, or worn vane bushings, can cause a significant increase in the cyclic loading imparted on the rotating blades in the compressor. Wear can be drastically accelerated by allowing the external surfaces to become dirty and/or oily over time. This mixture combines to form a paste very similar to lapping compound. Consequently, each time the system cycles, the wear surfaces are “lapped” and clearances increase at an ever accelerating rate. External surfaces can be cleaned following work package 4011.

Besides the HPC speed, the air inlet temperature has an influence on the required VGV positions. Therfore, the HPC speed signal XN25 will be corrected with a factor derived from the HP compressor inlet temperature T25.

SYSTEM OVERVIEW The illustration above is a simplified diagram of the LM6000 Hydraulic Starter System. For complete, sitespecific layout, instrumentation and settings, please refer to F&ID XXX232. The LM6000 hydraulic start system supplies hydraulic pressure to the hydraulic starter motor. This pressure is used to rotate the HP compressor during low-speed crank, high-speed crank, and start. The starter system is also utilized to perform offline water wash cycles and to crank engine during certain CDLO/FSWM shutdowns. The charge pump takes suction from the hydraulic oil reservoir and discharges the hydraulic oil to the suction side of the main pump, providing a positive suction for the main pump. The main pump discharges the oil at 5200 psig (35,853 kPag) at a flow rate of 56 gal/min (212 L/ min). The oil from the main pump is piped to the hydraulic starter motor on the accessory gearbox of the gas turbine. The oil pressure hydraulic starter motor, in turn, rotates the HP compressor through the accessory gearbox. Most of the oil from the hydraulic starter motor returns to the suction side of the main pump, but oil from the pump casing drains, then flows, through a return line to the temperature control valve. When the return oil is cool, the temperature valve sends the oil directly to the reservoir. When oil heats up during operation, the valve diverts oil to a fin-fan cooler and then to the reservoir. The hydraulic cooler fan pump is mounted on the end of the hydraulic pump assembly. This pump takes suction from the reservoir and discharges the oil to the hydraulic fan motor on the fin fan oil cooler. The discharge from the motor returns to the hydraulic oil reservoir.

Hydraulic Oil Reservoir The hydraulic oil reservoir is stainless steel. The reservoir is located on the auxiliary skid and has a 40 gal (151 L) capacity. The reservoir has local indication of level and a reservoir heater, which keeps lube oil temperature in the reservoir to at least 90 °F (32 °C). The reservoir also has a level switch, a temperature switch, and a suction strainer, which will bypass the strainer at 3 psid (20.6 kPad), located inside the reservoir.

Hydraulic Oil Charge Pump The charge pump is one of three pumps in the hydraulic pump assembly. The charge pump takes suction from the hydraulic oil reservoir and discharges the hydraulic oil at 350 psig (2413 kPag) at a flow rate of 12 gal/min (45 L/min) to the charge pump filter.

Charge Pump Filter The charge pump filter is a “spin on” type single stage filter. The filter has a visual indicator to show filter condition. The filter housing has a bypass valve that will open, bypassing oil around the filter if differential pressure across the filter reaches 50 psid (344.6 kPad).

LM6000 Start System (Woodward Control)

Main Hydraulic Oil Pump The main hydraulic starter pump, located on the starter skid, is driven by a three-phase, constant-speed, AC electric motor. The hydraulic starter pump has a variable swash plate, whose angle is controlled by software logic signals from the turbine control panel (TCP). The signals are applied to a solenoid operated valve (SOV) on the hydraulic starter pump assembly. The hydraulic starter pump supplies hydraulic fluid under high pressure to the turbine starter motor. As the hydraulic starter pump’s swash plate angle is increased or decreased, more or less hydraulic fluid under pressure is applied to the pistons in the turbine starter motor, thereby increasing or decreasing the revolutions per minute (rpm) of the starter and the turbine engine. Fluid pressure from the hydraulic starter pump is applied to pistons in the turbine starter motor causing the motor to rotate.

Hydraulic Starter Motor The hydraulic starter motor, located on the auxiliary gearbox of the LM6000, is driven by hydraulic fluid under high pressure from the main hydraulic oil pump. The hydraulic starter motor has a fixed angle swash plate with movable pistons. The high-pressure fluid forces the pistons to move within the cylinder, causing the motor to rotate.

Low Pressure Return Oil Filter The low-pressure return oil filter is a “spin-on” type single-stage filter. The filter has a visual indicator to show filter condition. The filter housing has a bypass valve that will open, bypassing oil around the filter if differential pressure across the filter reaches 25 psid (172.3 kPad).

Temperature Control Valve The temperature control valve regulates hydraulic oil return temperature by bypassing some oil around the lube oil cooler. The valve opens when the oil heats during operation and diverts the oil through the Fin-Fan cooler to the reservoir. Temperature control valve is set at 120°F (49°C).

Hydraulic Oil Cooler Pump The cooler pump is a gear type pump coupled to the main pump assembly which is driven by the electric motor. It draws suction from the reservoir and pressurizes a hydraulic fan motor in the hydraulic oil cooler.

Hydraulic Oil Cooler Pump Discharge Relief Valve The hydraulic oil cooler pump discharge relief valve protects the hydraulic cooler pumps from overpressurization, by discharging excess pressure back to the reservoir. The relief valve is set at 1200 psid.

LM6000 Start System (Woodward Control)

Centrifugal Starting Clutch In the starting motor output shaft a centrifugal clutch allows engagement of the starting motor to the gas turbine generator at the beginning of the start-up sequence, and disengagement as soon as the HP runs faster than the starting motor. At 4500 rpm’s XN 2.5 speed the control system will signal a shutdown of the hydraulic start motor. For proper clutch operation, the oil flow to the clutch should be continuously controlled to a minimum of .5 qt/minute (.47 L/min) and to a maximum of 1.25 qt/minute (1.18 L/min). An orifice plate controls this oil flow. This clutch is also referred to as an overriding or overrunning clutch. At standstill of the gas turbine generator and the starting motor, the pawls of the centrifugal clutch engage in the gear on the starting motor output shaft. Weak plate springs push the pawls in the gear teeth. As soon as the starting motor begins to run, it will drive the HP shaft. The pawls tend to move outwards due to centrifugal force, but as long as the starting motor supplies torque to the HP rotor, the claws will stay engaged by friction. At approximately 4500 rpm the control system will shut down the starting motor. This will cause the torque to reverse and, immediately, the claws will disengage. When during the shutdown sequence the gas generator runs down to standstill, the centrifugal force on the pawls will gradually diminish, allowing the weak springs to bring the claws to the starting motor gear. As soon as the HP shaft speed is below 1000 rpm, the gas turbine may be started again. The spring force in the clutch then overrides the centrifugal force of the claws, allowing full engagement of the claws.

LM6000 Start System (Woodward Control)

In an SSS clutch the input shaft has helical splines, which correspond to the thread of the bolt. Mounted on the helical splines is a sliding component, which simulates the nut. The sliding component has external clutch teeth at one end, and external ratchet teeth at the other (see Figure 1).

When the input shaft rotates, the sliding component rotates with it until a ratchet tooth contacts the tip of a pawl on the output clutch ring. This prevents rotation of the sliding component relative to the output clutch ring, and aligns the driving and driven clutch teeth (see Figure 1 and Figure 4).

As the input shaft continues to rotate, the sliding com-ponent moves axially along the helical splines of the input shaft, moving the clutch driving and driven teeth smoothly into engagement. During this movement, the only load taken by the pawl is that required to shift the lightweight sliding component along the helical splines.

Basic SSS Clutch Principle The initials SSS denote the 'Synchro-Self-Shifting' action of the clutch, whereby the clutch driving and driven teeth are phased and then automatically shifted axially into engagement when rotating at precisely the same speed. The clutch disengages as soon as the input speed slows down relative to the output speed. The basic operating principle of the SSS clutch can be compared to the action of a nut screwed onto a bolt. If the bolt rotates with the nut free, the nut will rotate with the bolt. If the nut is prevented from rotating while the bolt continues to turn, the nut will move in a straight line along the bolt.

LM6000 Start System (Woodward Control)

As the sliding component moves along the input shaft, the pawl passes out of contact with the ratchet tooth, allowing the driving teeth to come into flank contact with the driven teeth and continues the engaging travel (see Figure 2). Driving torque from the input shaft will only be transmitted when the sliding component completes its travel by contacting an end stop on the input shaft, with the clutch teeth fully engaged and the pawls unloaded (see Figure 3). When a nut is screwed against the head of a bolt, no external thrust is produced. Similarly, when the sliding component of an SSS clutch reaches its end stop and the clutch is transmitting driving torque, no external thrust loads are produced by the helical splines.

If the speed of the input shaft is reduced relative to the output shaft, the torque on the helical splines will reverse. This causes the sliding component to return to the disengaged position and the clutch will overrun. At high overrunning speeds, pawl ratcheting is prevented by a combination of centrifugal and hydrodynamic effects acting on the pawls. The basic SSS clutch can operate continuously engaged or overrunning at maximum speed without wear occurring.

GAS FUEL SYSTEM OVERVIEW The LM6000 PD engine allows the customer to operate with low Nox and CO emissions on gas fuel without need for water or steam injection. The turbine control system meters the customer-supplied fuel to the turbine combustor through the fuel manifolds and 75 dual-fuel nozzles. Gas fuel must meet General Electric fuel quality requirements. The gas fuel system contains piping, valves, a gas manifolds staging valves, 75 fuel nozzles, and control and monitoring instrumentation. The fuel gas system provides fuel gas in sufficient amounts to run the LM6000 through the full scale of operations. The fuel gas enters the enclosure base at the following conditions: •400 MMBtu/hr Max. •250°F (121°C) Max. •675 ± 32.5 Psig (4740 ± 224 kPag) •Filtered to 3 micron

GAS FUEL Duplex Coalescing Filter Skid Any accumulations of moisture left in the fuel could have detrimental effects on the gas turbine's sensitive fuel control. The duplex coalescer filter provided is necessary to remove any remaining water and sediment prior to entering the turbine. One duplex coalescer filter is supplied with each GTG unit. Each filter tower is split into two compartments; coalescer and sump. The coalescing filter separates water from the fuel and traps sediment prior to entering the turbine gas fuel system. The sump collects and drains off water separated by the coalescer. Each tower is equipped at the coalescer and sump with level transmitter, level indicators, and manual drains. The filters assembly also incorporates a pressure differential transmitter. This transmitter will alarm should the differential pressure between the inlet and outlet of the filter, suggesting a high level of moisture or contaminants in the filter, reach a predetermined set point. Should the operator receive this alarm, the filters should be switched and the coalescer elements replaced. The operator can monitor levels at the sump and coalescer locally by checking level indicator. Coalescer and sump levels can also be monitored at the TCP. One filter separator (tower) remains on-line while the other remains off-line as a backup. The filters are operated independently allowing the off-line filter to be placed out of service for cleaning without disrupting operations. F-060-00-20-301-02

Filter Separator Operation Fuel being delivered from a gas compressor or a system reducing valve is piped to the coalescer assembly. Gas is directed into one of the two filter separators (towers) after passing through a manual isolation valve. Each filter assembly (tower) is comprised of two compartments consisting of a coalescer and sump sub-assembly. Each sub-assembly is equipped with a remote level transmitter and local level indicator for monitoring. In addition; a differential pressure transmitter monitors the cleanliness of the on-line separator and will activate an alarm in differential pressure reaches 25 psid (172 kPaD). Each sub-assembly is equipped with a manual isolation condensate drain valve, which allows for draining the condensate from each individual assembly. Each filter assembly is equipped with a pressure safety valve that is set to lift (open) if pressure reaches 750 psig (5171 kPaG) and vents to atmosphere to protect the vessel from over pressurization. A manual vent valve is provided to depressurize the separator for maintenance. Discharge from the filter separator is piped to the gas turbine enclosure after passing through a pneumatic actuated fuel shutoff valve. A pneumatic actuated vent valve will depressurize the system when actuated. F-060-00-20-301-02

GAS FUEL SYSTEM – GT ENCLOSURE Fuel gas coming from the duplex coalescer filter has been filtered to 3 microns. Fuel gas enters the gas turbine enclosure through a manual isolation valve. Downstream of the isolation valve is a Y-type strainer to remove any large particulate contamination from the gas. Located after the strainer, a fuel flow transmitter monitors and transmits a signal to the turbine control system for fuel scheduling. A manual vent valve is located downstream of the flow transmitter to depressurize the piping for maintenance. BLOCK AND BLEED VALVES Located in the main fuel piping are two block valves and a vent valve. These are referred to as a double block and bleed type system. During shutdown of the system the two block valves will close to isolate the system and a vent valve will open, depressurizing the piping between the two block valves. The block valves are electronically operated, pneumatically actuated by fuel gas that has been pressure reduced to 40 psig (276 kPaG). To open the block valve, a signal from the TCP will electronically shift a 3-way solenoid valve that will port fuel gas to the block valve. Fuel gas will overcome the block valve actuation spring pressure (holding the block valve closed), opening the valve. In order to close the block valve, a signal from the TCP will electronically shift the 3way solenoid valve to vent to atmosphere the fuel gas holding the block valve open. F-060-00-20-301-02 Fuel System The actuation spring located in the LM6000 blockPD valve will force the valve closed.

These orifices limit the manifold pressure build up in a non flowing ring. This reduces the initial fuel flow pulse, and therefore flame temperature, when a ring is first fueled ( the first staging valve is opened). The fuel-metering valve is a rotary sleeve-and-shoe throttling valve. The metering port area is determined by input shaft positioning from the actuator. The valve is springloaded to the minimum fuel direction, so that loss of signal and loss of power situations will cause a fuel shutdown. The rotary fuel-metering valve actuator is an electrohydraulic proportional device. In the actuator, a torque motor servo-valve is actuated by a rotary servo motor through a precision gear assembly. The valve position demand signal from the fuel control in the TCP is converted to high-current motor drive signal by the digital drive module.

Staging Valves (11) The flame temperature range is limited by thermal stress limits on the high side and lean blowout on the low side. The minimum bulk or average flame temperature for an LM6000 ranges from approx. 3300 deg F at noload sync idle to approx. 2900 deg F at maximum power, whereas the maximum bulk or average flame temperature ranges from approximately 3450 deg F at no load syncidle to approximately 3000 deg F at maximum power.

With such a limited flame temperature operating range, it is necessary to "stage" the combustor, i.e. it is necessary to turn sections of the combustor "on" and "off" .

LM 6000 DLE COMBUSTOR OPERATING MODES There is a limited operating power range for each combustor configuration. Operating at a higher power than intended in a given combustor configuration means exceeding the max allowable average flame temperature and can result in extensive damage to the combustor.

Attempting to operate at a lower power than intended in a given combustor configuration means attempting to run below the min allowable flame temperature and can result in blowouts.

From the burn mode illustration it can be seen that there are "gaps" between each configuration, i.e. power regions in which the DLE engine could not run. This is overcome by using compressor bleed. F-060-00-20-301-02

This allows fuel gas to flow to the fuel control valve and to the gas turbine. FUEL GAS VENT VALVE The fuel gas vent valve is a failed open type solenoid valve. This valve works with the fuel gas shutoff valves. When the fuel gas shutoff valves are closed, the vent valve is open, venting the piping between the shutoff valves to a safe area.

Gas Fuel Valve Overview The EM35MR1 electric actuator is used to drive a 3103 gas valve, closed loop to position demand. Position feedback is provided by a resolver connected to the valve metering sleeve. Closed loop position control is accomplished through an EM 24V Digital Driver. Having the feedback on the valve allows the motor assembly to be repaired or changed in the field without the loss of valve calibration. 3103 Gas Valve The 3103 Gas Valve is a stainless steel valve capable of metering gas flow between 50 and 40 000 pph. The valve is designed to bolt into a 2 inch (51 mm) line by means of tapped holes. The valve design is a rotary metering sleeve and a shoe-type throttling valve. The valve shoe is spring- and pressure-loaded against the metering port to minimize leakage and to self-clean the metering port. Metering port area is determined by input shaft positioning from the actuator. The valve has an internal spring to return the valve to the minimum fuel position in the event of a power loss to the actuator.

The 3103 valve has redundant seals on all dynamic sealing surfaces. Between these two seals is an overboard vent which vents any gasses that may leak past the first seal to safe vent location. The use of an inner-seal vent prevents the second dynamic seal from seeing any differential pressure and thus offers protection against the leakage of gasses from the valve into the surrounding ambient atmosphere. The valve design incorporates an inlet guide tube to condition the inlet flow and to direct any gas contaminants through the metering port, minimizing any accumulation in the valve housing. The metering sleeve support bearings are positively sealed from the gas. Internal valve parts are made of through-hardened stainless steel.

The use of a high efficiency gearbox facilitates high servo system bandwidth. The motor has its own resolver providing motor rotor position feedback, and the other resolver(s) provides accurate output shaft position feedback. The actuator also has a slip clutch to allow full speed impact into optional external rigid mechanical stops. The motor assembly is housed in a cast aluminum explosion proof housing. A thermal potting compound is used to transfer waste heat generated by the motor, to the cast, explosion-proof housing and out to the ambient environment. The motor output shaft is directly coupled to the valve input shaft through the use of a stainless steel torsional coupling.

SYSTEM OVERVIEW The ventilation and combustion air system can be divided into the following three (3) sub-systems; the gas turbine enclosure ventilation air system, the generator enclosure ventilation air system and the gas turbine combustion air system. GAS TURBINE ENCLOSURE VENTILATION AIR SYSTEM The gas turbine ventilation air system provides the gas turbine enclosure with sufficient ventilation air to cool the gas turbine exterior and the inside of the enclosure. Air flows through the filters in the filter house. From the filter house the air flows down the ductwork into the gas turbine enclosure. Next the air is removed from the gas turbine enclosure by the enclosure/exhaust fans and is discharged back to the atmosphere. This maintains the gas turbine enclosure under a negative pressure. GAS TURBINE COMBUSTION AIR SYSTEM The combustion air system provides a sufficient amount of combustion air (approximately 230,000 scfm (6512.8 scmm) for the LM6000 to operate at all required operating levels. Air enters the filter house and flows through the chiller / heater coils. Then the air flows through barrier filters, drift eliminator located in the filter house, down the duct to the inlet bellmouth screen (last chance) and into the inlet volute. The inlet volute turns the airflow from a downward flow to a horizontal flow and into the LM6000 gas turbine. From the LM6000 the exhaust gases pass thru outlet guide vanes which will evenly distribute the exhaust gases thru the exhaust collector before discharged back into the atmosphere.

From the generator enclosure the air flows into each end of the generator. On the driven end of the generator the air flows along the rotor shaft and is then discharged into the generator exhaust and back to the atmosphere. On both ends of the generator rotor shaft are mounted fans that draw air from the generator enclosure. Most of the air flows along the rotor shaft and is then discharged into the generator exhaust. A portion of incoming air flows across the exciter and is then discharged back into the generator air-cooling stream.

Filter House Air enters the filter house and flows through various customer selected filtration, cooling and anti-icing equipment. The air flows through the barrier filters in the filter house, down ducts to the combustion air inlet volute and to the two enclosures for cooling. There are numerous options the customer may select depending on the operating environment. They are:

Filtration Barrier filters (high efficiency filter) may consist of a canister or bag type filter element. All units will have barrier filters as these are the primary filter for the unit. Inlet screens are a large mesh, stainless steel screen mounted on the opening to the filter house to prevent birds and large sized garbage from entering the filter house. Guard filters are a disposable pre-filter used to extend the operating life of the barrier filter. They are easy to change out and less expensive than the barrier filters. Drift eliminators are moisture separators designed to remove water droplets from the airflow.

The guard filter is an disposable filter utilized to catch a majority of the airborne contaminates which will prolong the life of the more expensive barrier filters. When differential pressure increases to an alarm state, the filter assembly will be replaced and the old filter disposed. BARRIER FILTERS The barrier filters, which are made of a composite type material, are high efficiency media which filters the incoming ventilation air to remove any solid contamination. The canister type media has a pre-filter that inserts into the canister to help prolong the life of the canister.

Ventilation Fans The gas turbine enclosure ventilation fans remove hot air from the gas turbine enclosure and discharge the air back into the atmosphere. Because of this arrangement the gas turbine enclosure has a “negative” pressure. This prevents any gas migration from the gas turbine enclosure to the generator enclosure. Normal operation is to run one fan and have one fan as back up. The fans are belt driven by electric motors.

Fans will alternate as lead fan upon each start.

Each fan is rated at 60,000 scfm (1699.01scmm) and is 66” (1.68 meters) in diameter.

Generator Enclosure Ventilation Fans (2) The generator enclosure ventilation fans force cooling air from the filter house into the generator enclosure. Because of this fan arrangement the generator enclosure has a “positive” pressure. This prevents any gas migration from the gas turbine enclosure to the generator enclosure. The fans are direct driven by electric motors. Normal operation is to run one fan and have one fan as back up. Fans will alternate as lead fan upon each start. Each fan is rated at 45,000 scfm (1274.25 scmm) and is 42” (1.07 meters) in diameter.

Icing Conditions and Anti-Icing Systems

Note from the table above that icing conditions are possible at temperatures above 32 degF (0 degC). Temperature protection is provided in the form of an alarm that is generated at 43 degF (6 degC). This alarm alerts the operator to the possibility of icing conditions. In the event of such an alarm, it is the operator’s responsibility to check the relative humidity and determine if anti-icing measures should be taken. Anti-icing requires heating of the inlet air. This may be accomplished by one of several means. In systems equipped with chiller coils, it is possible to circulate heated fluid (typically glycol) through the chiller coils. In some systems, there are ducts which allow turbine enclosure exhaust air to be introduced to the inlet for anti-icing. In other system, turbine exhaust is used to heat inlet air. Note that turbine exhaust is never introduced directly into the turbine inlet air.

GE Energy THEORY OF OPERATION

The water wash system provides a mechanism for cleaning engine compressor blades to increase compressor efficiency and improve engine power output versus fuel burned. There are many types of compressor fouling. The type and rate of fouling depend on the environment in which the gas turbine operates and the type of inlet filtration. Among the most common types of contaminants are: Ø

Dirt or soil

Ø

Sand

Ø

Coal dust

Ø

Insects

Ø

Salt (Corrosion)

Ø

Oil

Ø

Turbine exhaust gas

Salt, aside from being a contaminant by itself, also causes corrosion of blading and ductwork and subsequent ingestion of rust and scale. Oil increases the ability of contaminants to cling to compressor passages and airfoils. The type of material that is deposited on the compressor blading influences the method of its removal. In other words, some material will respond to one cleaning media, others to another. Keeping the compressor internals clean can alleviate a number of problems before they ever become apparent. Besides the obvious benefits of enhanced efficiency (increased power output, lower T-3 temperatures, etc.), keeping the HPC clean will help blades survive longer. If the compressor is dirty, additional weight is added to the airfoil and this increases the cyclic stress. Also, dirt in the dovetail slots will add to the existing friction loading at the dovetail/slot interface and between the two mechanisms making a blade dovetail failure, more likely. Performing thorough water washes with high quality ingredients on a regular basis with help combat these conditions. F-060-00-20-500-00

GE Energy Methods of Detection •Visual •Performance Monitoring

VISUAL INSPECTION The best method for detecting a fouled compressor is visual inspection. This involves shutting the unit down, removing the inlet plenum inspection hatch, and visually inspecting the compressor inlet, bellmouth, inlet guide vanes, and early stage blading. If there are any deposits, including dust or oily deposits that can be wiped or scraped off these areas, the compressor is fouled sufficiently to affect performance. The initial inspection reveals whether the deposits are oily or dry. For oily deposits, a water-detergent wash is required, followed by clean water rinses. The source of the oil should be located and corrected before cleaning to prevent recurrence of the fouling.

g

LM6000 Water Wash System

GE Energy PERFORMANCE MONITORING

A second method for detecting a fouled compressor is performance monitoring. Performance monitoring involves obtaining gas turbine data on a routine basis, which in turn is compared to baseline data to monitor trends in the performance of the gas turbine.

The performance data is obtained by running the unit at a steady base load and recording output, exhaust temperatures, inlet air temperatures, barometric pressure, compressor discharge pressure and temperature, and fuel consumption. The data should be taken carefully with the unit warmed up. If performance analysis indicates compressor fouling, it should be verified by a visual inspection.

Washing and rinsing solutions are mixed in a holding reservoir and pumped into nozzle rings in the engine air inlet under controlled pressure and flow rates for optimum cleaning. Operators are responsible for charging the reservoir and initiating the washing and rinsing cycles. Software logic then operates the pump and valve controls, based upon operator mode selections and engine safety permissives.

Following the release of washing and rinsing solutions into the engine, a software- controlled air purge of the nozzles prevents contamination or blockages in the feed nozzles.

The flow and instrument diagram illustrates separate nozzle rings in the engine inlet for on-line and off-line cleaning. Droplet size is larger in the off-line ring, allowing greater flow volume than is permissible when the engine is running. Smaller droplets are necessary in on-line operation to avoid blocking compressor blades at speeds above core idle. Cold weather operations require the addition of anti-freeze. Be sure to check manufacturer’s information for mixing of soap solution and antifreeze to ensure compatibility. Operators initiate washing by closing the tank drain, discharge, and water fill lines. After introducing recommended chemical amounts, the chemical inlet valve is closed and the water fill valve is opened. The engine manufacturer recommends 150 °F–180 °F (66 °C – 82 °C) water temperature. For units without the tank heating option, water preheating is recommended. A sight gage is provided to avoid overfilling. After charging the reservoir, WASH mode is selected on the turbine control panel (TCP). If the engine is not running, an off-line sequence is enabled.

VIBRATION MONITORING SYSTEM THEORY OF OPERATION The vibration monitoring system produces vibration magnitude data with adjustable alarm and shutdown set points for engine and generator safety. The previous figure illustrates the LM6000 engine and generator vibration sensors and electronic components. Aft and forward engine accelerometers are installed on the turbine rear frame (TRF) and compressor rear frame (CRF). These sensors produce complex electrical waveforms, resulting from the frequency and amplitude of engine vibration. Interface modules, installed in relative close proximity to the sensors, integrate 10-mV/g acceleration signals to obtain 100-mV/sec velocity signals for processing in modules that plug into the control rack. The rack is mounted in the turbine control panel. Tracking filters receive low-pressure turbine (LPT) and high-pressure turbine (HPT) velocity and speed signals. The tracking filters present the velocity components associated with the two turbine speeds on front panel displays. In summary, four velocity signals are produced: one from each accelerometer, filtered at XN25 and at XNSD speeds. They are noted as follows: •Engine (FWD) vibration velocity at (HPC) speed •Engine (AFT) vibration velocity at (HPC) speed •Engine (FWD) vibration velocity at power turbine (LPT/LPC) speed •Engine (AFT) vibration velocity at power turbine (LPT/LPC) speed

Accelerometer Theory of Operation In the study of physical systems, it is often desirable to observe the motion of a system and, in particular, its acceleration. An accelerometer can be described as a combination of the two transducers – the primary transducer, typically a single degree of freedom vibrating mass, or seismic mass, which converts the acceleration into displacement, and a secondary transducer which converts the displacement of the seismic mass into an electric signal. As the accelerometer reacts to motion, it places the piezoelectric crystal into compression or tension, which causes a surface charge to develop on the crystal. The charge is proportional to the displacement of the crystal. As the large body moves, the mass of the accelerometer will move with an inertial response. The piezoelectric crystal acts as the spring to provide a resisting force and damping. As the seismic mass moves, it places a piezoelectric crystal into compression or tension, which causes a surface charge to develop on the crystal, which is proportional to the motion.

LM6000 FIRE PROTECTION SYSTEM

FIRE SYSTEM OPERATION The fire protection system utilizes flame, thermal, and gas detectors in the generator and turbine enclosures to detect fire or fire-causing conditions. The system activates precautionary alarms or engine shutdown commands under specific conditions. Fire-extinguishing CO2 is released into the enclosures if flames are detected or temperatures rise above set limits. Backup ventilation fans are activated to exhaust explosive gases from the enclosures should gas-air mixtures reach dangerous levels. Pressure from CO2 in the release lines activates pneumatic actuators, pulling pins that allow weights to fall, thus closing louvers (fire dampers) in the ventilation ducts. These fire dampers reduce the supply of oxygen and confine CO2 within the enclosures for maximum effect.

THEORY OF OPERATION Because of its importance to the system while running, and in Standby or Static state, the Allestec Fire Protection system performs a routine “system check” every 36 hours. At time of initial power-up, the FPP sets an internal watchdog timer that initiates a status check at 36-hour intervals. During this period the system looks at each circuit run to the manual switches, heat sensors, flame detectors, gas detectors, pressure switches and battery charger system to verify proper operating parameters of the external components. If a device is not functioning properly, or if the system detects a loss of circuit continuity, an alarm will be annunciated and displayed on the Operator’s Alarm and Shutdown screen on the HMI.

LM6000 FIRE PROTECTION SYSTEM INFRARED FLAME DETECTORS A total of four dual-element infrared flame detectors signal the fire control modules when flames are present. Three of these detectors are located in the turbine enclosure and one is located in the generator enclosure. The detectors are filtered for different wavelengths in the infrared spectrum, and are activated by the spectral characteristics of light emitted from hydrocarbon flames. In the gas turbine enclosure, 2 of 3 sensors need to detect the fire for 2.5 seconds before initiating fire alarm/shutdown. The single generator sensor needs to detect flames for 2.5 seconds prior to initiating alarm/shutdown.

LM6000 FIRE PROTECTION SYSTEM Alarm Horns Alarm horns, located in the turbine and generator enclosures and outside the package, will sound if fire or gas is detected. CO2 is released 30 seconds after the alarm horns sound. A manual key-switch is provided as a “Horn Acknowledge” mute switch. Strobe Lights Strobe lights emit a bright, flashing red light whenever the fire suppression system has been activated.

NOTE: Except during an actual response to a fire Alarm/Shutdown condition, if the system initiates a 36hour status check, any condition such as a manual inhibit mode will be reset. Operators should utilize the use of the manual shutoff valve ZS-6364 located in the CO2 enclosure when doing a quick internal package inspection. Situation could arise while in an inhibit-only mode to perform an inspection, system could initiate the 36-hour check and reset inhibit status.

INTRODUCTION TO ELECTRICITY All matter is composed of atoms that often arrange themselves into groups called molecules. The atom is composed of smaller particles separated by space. The center of the atom is the nucleus that contains various particles, including protons. These protons are said to have positive charge. The electrons, which complete the atomic structure, are said to orbit the nucleus and have a negative charge. Different atoms have different numbers of electrons, and atoms in their complete state have equal numbers of electrons and protons. In this structure, the positive and negative charges cancel out each other, leaving the atom electrically neutral. Consider the copper atom; notice the outer electron is farthest from the nucleus and subject to a smaller force of attraction than those electrons in the inner orbit. This electron is weakly held in position and often breaks free, moving at random among the other copper atoms. An atom that loses an electron in this way is left with an overall positive charge, since it has a positive proton in excess of those required to balance the effect of the negative electrons. Such an atom is called a positive ion. Electrons in motion constitute electric current. By the laws of nature, opposites attract. If opposite-charged materials are connected electrically in some way, current will flow to the movement of electrons from negative to positive.

ELECTRIC CURRENT IN A BLOCK Consider a block of conducting material. Free electrons are moving at random among positive ions. If a battery is connected across the block, free electrons close to the positive plate will be attracted to it and free electrons near the negative plate will be repelled from it. A steady flow of electrons occurs from the negative battery terminal to the positive terminal. For each electron entering the positive terminal, one is ejected from the negative terminal, thus the total number of electrons in the material remains constant. VOLTAGE, CURRENT, AND RESISTANCE To consider the basic DC circuit we must introduce the notion of voltage. Consider our basic circuit, the battery connected across the piece of material. The reason there is current flow is because there is an excess of electrons at the negative terminal and a deficiency of them at the positive one. We say there is a difference in potential between the positive and the negative terminals, and we measure this potential difference in volts. Adopting the physical analogy to electricity, we can say the following: In order for electrons to move, a force must be applied. This force is called electromotive force (EMF) and is measured in volts. In all conducting materials there is a resistance associated with electron movement. This is the electrical resistance and is measured in ohms.

OHM’S LAW The conditions required to set up and maintain the flow of electric current are as follows: • There must be a source of EMF (battery or generator • There must be a continuous external path (circuit) for the current to flow in Consider the simple circuit shown on the previous page. When the switch is closed, a current will flow. The value of this current depends on the battery EMF (in volts) and the amount of resistance in the circuit. The relationship between EMF, current, and resistance is defined in the statement called Ohm’s law. The current flowing in a circuit is directly proportional to the applied voltage. EMF is inversely proportional to the resistance. We tend to express this relationship mathematically as follows: I=V/R I = Current (A) V = EMF (V) R = Resistance (R) This gives us the “magic triangle” from which is given two of the circuit parameters; we can deduce the remaining one.

POWER To complete the definitions portion of this section, we need to consider power. We define power as the rate of doing work. Whenever a force of any kind causes motion, work is said to be done. A difference in potential between any two points in an electric circuit gives rise to a voltage, which causes electrons to move and current to flow. Thus, force causes motion and work is done. So whenever voltage causes electrons to move, work is done in moving them. The rate at which the work of moving electrons from point to point is done is called electrical power. The unit in which it is measured is the watt (W). It is defined as “the rate at which work is being done in a circuit in which a current of 1 ampere (A) is flowing when the EMF applied is 1 volt (V)”. In real terms, power is the rate at which electrical energy can be converted into useful forms of energy, such as heat or light. Electrical power is expressed in watts (W), kilowatts (kW), or megawatts (MW). One horsepower of mechanical energy is equal to 746 W or about ¾ kW (1000 W = 1 kW). As an example, 13,800 volts × 1500 amperes = 20,700 kW (20.7 MW). This example provides for the instantaneous amount of electrical power being generated. The total energy produced by the generator is expressed in kilowatt-hours. As an example, 20,000 kW × 2 hours of generation = 40,000 kilowatt-hours. The formula for calculating kW (shown in the above illustration) is valid for directcurrent (DC) circuits and for alternating-current (AC) circuits when the AC voltage and current are in phase with each other. The power (P) consumed in a resistor is determined by the voltage measured across it, multiplied by the current flowing through it. The following power formula results: P = V × I Watts = Volts × Amps.

CONDUCTORS AND INSULATORS In the simple model we have been considering, we introduced the notion of conductors. The piece of material, which permitted electron flow, is a conductor. Copper wire is considered a good conductor since it contains many free electrons. Given an electric force (voltage) acting in a particular direction, electrical energy will be transferred through the conductor by the directional movement of free electrons migrating from atom to atom within it. Each electron only moves a very short distance to a neighboring atom, where it forces one of that atom’s electrons from its outer orbit by mutual repulsion of like charges and then takes its place. The displaced electron repeats the process in another nearby atom, until the movement of electrons has been transmitted through the conductor. The more electrons that can be made to move for a given applied electric force, the better the conductor. Popular conductors in use in the power industry today are aluminum and copper, with aluminum preferred, owing to its lower price. Materials possessing very few free electrons are called insulators. In these materials, a lot of energy is required to force electrons out of their orbit about the atoms. Even then only a few can be forced out at any one time. No such thing as a perfect insulator exists and in that sense, they can be thought of as very poor conductors.

MAGNETISM Let us consider a common bar magnet. Magnetism about the magnet is exhibited in the form of lines of force. These invisible lines of force are called flux lines and the shape of the area they occupy is called the flux pattern or magnetic field. The magnetic lines of force always travel out from the North Pole and reenter the magnet through the South Pole. Inside the magnet the lines of force travel from the South Pole to the North Pole. This way, the lines remain continuous and unbroken and the complete path they take is called the magnetic circuit. Flux lines per unit area, or flux density, are greater at the ends of the coil, where flux lines leave the “north” pole and enter the “south” pole. Pushing two similar poles of different magnets together, you experience a force of repulsion between them. By bringing similar poles together, one can feel a strong force of attraction. It is a characteristic of all magnetic lines of force that they always tend to repel one another and never unite or cross. Two magnetic fields, which are brought close together, will deform themselves into considerably distorted flux patterns, but will not cross each other. The type of magnet we have been considering is the natural phenomena of permanent magnetism that is exhibited in some natural materials. It is possible, however, to induce magnetism in a material by means of electricity. This is known as electromagnetism.

CURRENT FLOW IN A CONDUCTOR If a magnet is moved past a piece of wire, electric current is induced in this wire. The current is induced only when the magnet is moving. As the diagrams demonstrate, you can increase the amount of electricity produced by increasing the speed with which the wire is passed back and forth about the magnet, use a stronger magnet, or use more coils of wire. The energy required to produce relative motion is analogous to the energy used in rotating a mechanical pump to produce liquid flow, as illustrated above. The circulating liquid flow is analogous to current flow in the electric circuit. The switch in the electrical circuit is analogous to the valve in the mechanical liquid circuit.

ELECTROMAGNET AND RIGHT-HAND RULE One of the effects of a conductor carrying a current is to produce a magnetic field. Any conductor carrying a current will, in fact, act as a magnet. If we cause current to flow in a piece of wire, a magnetic field is induced. The converse is also true—if you move a piece of wire so that it cuts through a magnetic field, an electric current will flow in the wire. Forming the conductor in the previous illustration into a coil, as illustrated above can increase magnetic field strength. To make the magnetic field of the loop stronger, form the wire into a coil containing many loops. The individual fields of all the loops reinforce one another and form a single strong magnetic field, extending both inside and outside the loop. The field strength of the coil will then be proportional to current flow and the number of turns in the coil. The magnetism also increases with increasing current. Note that once current ceases to flow in the conductor, magnetism is lost. Flux lines per unit area, or flux density, is greater at the ends of the coil where flux lines leave the North (N) pole and enter the South (S) pole. The direction of the magnetic field about a current-carrying conductor is determined by the direction of current flow. If a current-carrying conductor is grasped in the right hand with the thumb pointing in the direction of current flow, the fingers wrapped around the conductor will point in the direction of the magnetic lines of force. This is known as the “Right-Hand Rule.”

ELEMENTARY GENERATOR In order to understand the ac waveform, it does well to examine how it is produced. To do this, we need to understand the mechanism of ac power generation. An elementary generator consists of a loop of wire placed so that it can be rotated in a uniform magnetic field to produce electricity in the loop. If sliding contacts are used to connect the loop to an external circuit, a current will flow around the external circuit and the loop. The pole pieces are the North and South Poles of the magnet that supply the magnetic field. The loop of wire that rotates through the field is called the armature. The ends of the armature loop are connected to rings called slip rings, which rotate with the armature. Current collectors, called brushes, “brush off” the slip rings to pick up the electricity generated in the armature and carry it to the external circuit. In the description of the generator outlined, visualize the loop rotating through the magnetic field. As the sides of the loop cut through the magnetic field, they generate an emf, which causes a current to flow through the loop, slip rings, brushes, ammeter, and load resistor, all connected in series. The emf, which is generated in the loop and, therefore, the current that flows, depends on the position of the loop in relation to the magnetic field. ALTERNATING-CURRENT FREQUENCY We have seen that as the loop of the elementary generator rotated through 360 degrees, one complete revolution, the generated emf completed one cycle. If the loop rotates at a speed of 60 revolutions per second, the generated emf will complete 60 cycles per second (c/s). It will then be said to have a frequency of 60 cycles per second. The units we use for frequency are hertz (hz = c/s). Frequency is the number of cycles per second. The standard commercial frequency used in the United States is 60 Hz. Other parts of the world use frequencies of 50 Hz. Lower than 50 Hz causes problems; for instance, a visible flicker of lights can be seen using an electrical supply of less than 50 Hz. This is because every time the current changes direction, it falls to zero and momentarily switches off an electric lamp as it does so. At 50 c/s, the lamp switches on and off at 100 times per second (faster than the human eye can detect, and therefore, we have the impression that the lamp is permanently lit). At lower frequencies, it would be possible to discern this switching.

SIMPLE SINGLE-PHASE GENERATOR Illustrated above is a permanent magnet with high permeability rotating near a single-loop conductor. As the N and S poles rotate (to positions) near the loop, the flux density is increased and reversed when the opposite pole approaches. The reversal in flux direction produces a once-per-cycle reversal in current flow, such that an oscillating waveform is produced. The waveform produced is sinusoidal, having a peak-positive value as each N pole passes and a peak-negative value as each S pole passes. By positioning three loops, or coils, around a rotating magnet, as illustrated in (A) above, three voltage waveforms are generated with each revolution. By arranging the coils 120 mechanical degrees apart (industry standard), three-phase power is produced, as illustrated in (B) on the next page.

The generating system illustrated in (A) above uses a rotating electric magnet rather than a permanent magnet. Current flow through the rotating windings is supplied by a battery and brushes, which contact rotating slip rings. A variable resistor in the external battery current loop regulates current flow through the rotating coil. This Excitation current determines the strength of the rotating magnetic field and, therefore, the voltage and/or power output from the stator windings.

TWO POLE GENERATOR The excitation scheme, illustrated in (B) above, provides magnetic linking of the stationary and rotating parts of the machine without using brushes. Brushless excitation has become an industry-preferred standard, eliminating the wear and failure problems associated with brush type exciters. In the brushless excitation scheme, the rotating flux lines of the permanent magnet induce an AC voltage in the surrounding stationary windings. This AC voltage is rectified, and the resulting DC is regulated and applied to a set of stationary windings called the Exciter Field. The exciter field windings surround an exciter rotor, which has induced in it an AC voltage. The AC voltage output of the exciter rotor is rectified by diodes, which also rotate. The DC output from the rotating diodes is applied to the main rotor to control the electrical output of the main stator windings. The regulation of exciter field current, therefore, is a mechanism for controlling the 3-phase generator output.

GENERATOR OVERVIEW Electric power generators convert rotational shaft horsepower into electrical energy. Typical output from electric generators furnished in GE Energy Products gas turbine-generator (GTG) packages with LM6000 engines is 50 megawatts (MW) under ideal conditions. The LM6000 engine produces approximately 55,000 shp. The limiting factor for production over 50 MW is the LM6000 engine. The Brush generator is rated for 60.5 MW, 13.8 Kv. The generator is oversized to provide added safety margins and provide for future power increasing enhancements developed for the engine. The generator is installed in an isolated, pressurized enclosure to prevent explosive gas leakage from the engine into the generator compartment, where possible ignition could occur. It also provides enclosed filtered air for cooling of the generator. The unit is bolted to the gas turbine-generator package main skid, such that the rotor is axially aligned with the engine drive shaft. A flexible coupling through the engine intake connects the generator rotor to the engine’s low pressure compressor (LPC) drive shaft.

GE Energy MAJOR COMPONENTS

1. Stator Winding - High voltage coils are mounted in the generator frame. Rotor’s lines of force cut through these coils and create the generator’s output voltage. 2. Stator Core – Thin laminations of low-loss electrical steel are stacked together to form the generator core. The core concentrates the rotor’s magnetic flux in the stator coils and completes the path of the rotor’s magnetic loops. 3. Rotor – The rotor is a 12-ton, solid forging of nickel-chromium-molybdenum alloy steel. The rotor supports the field windings of solid copper bars. Current in the rotor windings creates magnetic flux around the rotor. This flux cuts the stator coils and produces the generator’s high-voltage output. 4. Rotor Endcaps – The rotor endcaps are non-magnetic steel. The endcaps cover and protect the end portions of the rotor windings. 5. Shaft-Mounted Fan(s) – Two fans (one on each end of the rotor) pull cooling air into the generator through top inlets at each end of the generator frame. The fans force the air over the rotor and core and out through the central top exhaust exit.

Exciter Cooling Air Duct – A fan on the exciter shaft pulls cooling air through this duct and forces the air over the exciter components.

8.

Endframe Bearing(s) – White-metal lined, hydrodynamic, cylindrical bearings support the rotor shaft at each end. These bearings require continuous lubrication while the rotor is turning.

9.

Exciter Stator – DC excitation current flows through these fixed stator coils, producing a magnetic field around the coils. The exciter rotor coils cut through this magnetic field, and a voltage is built in the rotating coils. Note: The energy is transferred to the rotating shaft without brushes, slip rings or physical contact.

10. Rotating Diodes – These diodes rectify the AC voltage in the Exciter Rotor Coils and produce DC current to energize the rotor main windings. 11. Exciter Rotor – A voltage is built in the Exciter Rotor coils when they cut through the magnetic flux of the Exciter Stator coils. This voltage is rectified by diodes, providing DC current to energize the main rotor windings. 12. Permanent Magnet Generator (PMG) – The flux from sixteen shaft-mounted permanent magnets cuts through the PMG stator coils and creates the AC utility voltage needed for excitation.

The generator frame is a box-shaped weldment built of carbon steel plates. The frame is stiffened internally by web plates. These plates are aligned by “key bars” running parallel to the axis of the machine. The key bars support the stator core. After fabrication, the generator frame is machined on a large lathe. The lathe cuts an accurate cylinder along the axis and provides machined faces on each end for mounting the generator end pieces. Main Rotor The rotor is machined from a single alloy-steel forging of tested metallurgical properties. Longitudinal slots are machined radially in the body in which the rotor windings are installed. The windings are secured against centrifugal force by steel wedges fitted into dovetail openings machined in the rotor slots. The coils are insulated from the slot walls by molded slot liners. Molded ring insulation is provided at the coil ends to separate and support the coils under thermal and rotational stresses. A centering ring held into place by shrink fit restricts axial movement. A single brush, spring-loaded against the rotor, carries stray ground currents from the rotor to the frame ground. The brush is located near the drive end of the main rotor.

The stator windings are arranged in patterns to minimize circulating currents. Conducting tape between the windings and the machine frame provides Corona protection. The stator core is a compressed stack of insulated, laminated steel strips. (The laminated construction reduces electrical losses in the core.) The stator core provides the “return path” to complete the rotor’s magnetic circuit. This concentrates the flux and produces more power in the stator coils.

The Neutral Cubicle mounts on the side opposite from the Lineside Cubicle. In the Neutral Cubicle, three of the generator terminals are connected together by busbar, creating a Wye arrangement, as shown in “B” above.

The Lineside cubicle connects to the high-voltage output terminals of the generator. The customer then connects the Lineside cubicle to the generator circuit breaker (52G) with busbar or high voltage cables. Three sets of lightning arrestors and surge capacitors are mounted in the Lineside cubicle. These devices “shortcircuit” lightning energy to ground and protect the generator if lightning should strike the grid. Neutral Cubicle The Neutral cubicle connects to the side of the enclosure opposite the Lineside cubicle. Busbars in the Neutral cubicle connect three phases together to form the “neutral point” of the generator Wye connection. The neutral point connects to earth ground through the Neutral Grounding Transformer. The Neutral cubicle also contains three sets of current transformers. These transformers tell the control system how much current is flowing in each of the three phases of the generator. The control system uses these 0-5 Amp signals for metering and relaying. Neutral Grounding Transformer The Neutral Grounding Transformer connects the neutral point of the generator’s Wye connection to ground. Grounding generators in this fashion provides a “common potential reference” for all the generators connected to a grid. This allows them to work smoothly in parallel. The Neutral Grounding Transformer also limits the maximum current flow from ground back into the generator if a “phase conductor” should accidentally fall to earth or become grounded

Exciter and Diode Assembly The exciter assembly consists of a permanent magnet generator (PMG), an exciter stator and rotor, and a rotating diode rectifier. These components are installed at the non-drive end of the generator shaft. The PMG stator consists of a single-phase winding in a laminated core. Twelve permanent magnets rotate on the rotor inside the stator. The PMG output AC voltage is rectified and regulated by the modular automatic voltage regulator (MAVR). The exciter stator, which receives the MAVR output DC voltage, is mounted around the exciter rotor. It consists of a stationary ring that supports the stator poles and carries the magnetic flux between adjacent poles. Stator windings are series-wound around laminated poles. The exciter rotor is constructed from punched laminations and contains resin- impregnated, form-wound, and three-phase windings. A rotating diode assembly rectifies the AC voltage induced into the exciter rotor.

The rectifier is a three-phase, full-wave bridge rectifier with parallel, individually fused diodes. The fuses are mounted on the reverse side of the diode assembly. The redundant diode configuration enables the exciter to carry full generator output with as many as half the diodes out of service. Because diodes have only two failure modes (shorted or open), the fuses provide over current protection and allow continued normal operation, unless two fuses open in any one of the six rectifier legs. A radio transmitter, powered by the rectifier DC voltage output, discontinues transmission, should a rotor ground fault occur. A stationary radio receiver generates an alarm, should the transmitter signal cease. Diode failure detection is accomplished by sensing ripple induced into the exciter field caused by the unbalanced load.

Diode Failure Detection Twelve diodes, each with a fuse in series, are mounted in parallel pairs in a three-phase bridge. Six of the diodes has positive bases and are mounted on one heat sink, the remaining six have negative bases and are mounted on the other heat sink. The risk of diode failure is very remote. However, if a diode does break down a heavy reverse current will flow which is interrupted by the fuse. The adjacent diode and fuse would then be called upon to carry the whole current that was previously divided between two parallel paths. Each path is designed with sufficient surplus capacity to carry the full current continuously. The generator will therefore continue running as if nothing had happen.

LM6000 50 HZ Generator Lube Oil System

System Overview The generator lube oil system uses mineral lube oil to lubricate, cool and cleans the gearbox and generator bearings. In addition, the mineral oil is used to lift the generator rotor shaft for easier “break-away.” The generator lube oil system has two distinct subsystems: a pressurized supply system and a separate jacking oil system, which lifts and centers the generator rotor for starting. Each subsystem has its own filters. The supply system has three pumps: one D/C motor driven supply oil pump and two A/C motor driven pump. A Single A/C motor-driven pump provides lubricating oil during operation. In case of pump failure, when the header pressure drops to 20 psig (138 kPaG) the standby A/C pump comes online. If pressure continues to drop to 12 psi (82 kPaG), the D/C motor driven pump will start to provide oil to the system. In the event of a complete electrical or mechanical system failure, four 20 gal (76 L) rundown tanks are provided to gravity feed oil to the bearings on both the generator and gearbox. (2 per unit) The jacking oil pump is used during startup and provides high-pressure oil to the rotor shaft to “lift” the shaft up on a cushion of oil so “break-away” is easier. The system also contains the following: a reservoir, lube oil coolers, piping, valves, and instrumentation.

Generator Supply Oil System The generator A/C and D/C motor driven supply pumps are located on the top of the lube oil reservoir. The supply pumps take suction from the 3000-gallon (11356 liter) stainless steel generator lube oil reservoir (mounted on the generator lube oil skid).

Discharge pressure from the supply element is regulated to 30 psi (206 kPaG) by a pressure control valve and then piped to the supply lube oil cooler. From the supply lube oil cooler, the lube oil is piped to the supply oil duplex filters (rated at six (6) microns). From the filters, the lube oil goes to the lube oil header, to the rundown tanks, and to the bearings on both the gearbox and generator. The lube oil is then returned to the generator lube oil reservoir by return oil piping.

50Hz Gearbox Assembly For 50Hz applications, the 3600 rpm output speed of the LPT must be reduced to 3000 rpm. This is done via a reduction Gearbox attached to the LPT output shaft and the Generator Drive End.

After the lube oil has passed through the oil supply filter, it flows through a check valve and then to the gearbox where it lubricates the gearbox’s four bearings. Temperature elements TE-6079, TE-6080, TE-6081, and TE-6082 indicate the temperature of the lube oil inside the gearbox. Temperature alarms TAH-6079, TAH-6080, TAH-6081, and TAH-6082 signal if the temperature of the lube oil reaches 107 °C (225 °F) increasing. A FSLO is initiated by alarms TAHH-6079, TAHH-6080, TAHH-6081, and TAHH-6082 if the lube oil reaches 116 °C (240 °F). After the lube oil has passed through the gearbox, it returns to the lube oil reservoir through a 305 mm (12inch) drain line. Temperature indicator TI-6083, scaled -20–120 °C (0250 F), indicates lube oil temperature upstream from the flow indicator. On the generator/gearbox lube oil skid, the lube oil passes through flow indicator FI-60004 before it returns to the reservoir. LM6000 50 Hz Generator Lube Oil System Slide 6

GENERATOR JACKING OIL SYSTEM The generator jacking oil system centers the generator (axially) and “lifts” the generator rotor on a highpressure layer of oil for easier “break-away.” The jacking oil pump is a four (4)-element pump, two (2) high-pressure elements rated at 2850 psig (19,650 kPag), and two (2) low-pressure elements rated at 800 psig (5516 kPag). Each pump element has a separate simplex discharge filter. The jacking oil pump takes suction from the generator lube oil supply header. The HP oil is supplied to each side of the thrust bearing to axially center the rotor shaft. The LP oil is supplied to each journal bearing to “lift” the rotor shaft up on a cushion of oil. This eliminates friction between the shaft and the bottom half of the journal bearing making “break-away” easier.

Temperature Control Valve The temperature control valve regulates lube oil return temperature by bypassing some of the hot oil around the lube oil cooler and mixing it with the cooled oil from the oil cooler. The thermostatic valve is a fully automatic, three (3)-way fluid temperature controller for mixing application.

Temperature is sensed at port “A” (valve outlet). Port “B” remains fully open until oil temperature reaches approximately 131F (55 C) to 133F (56 C). As the oil temperature continues to rise port “B” starts to close off and port “C” starts to open, mixing the hot and cool oils. Port “B” is fully closed and port “C” is fully open if oil temperature reaches 149F (65 C) to 151F (66 C). The valve continually modulates the oil flow, maintaining a nominal oil temperature of 140 F (60 C).

GENERATOR BEARINGS (CONT). The bearings are supported in fabricated steel housings, which are bolted directly to the generator ends. The bearing housings are split on the horizontal centerline with the lower half forming the bearing oil sump. The bearings are of plain cylindrical design, white metal lining, and spherically seated within the bearing housings. Oil under pressure is fed to the bearings and distributed over the bearing surface by internal grooves. Oil drains into the bottom of the bearing housing. From the housing, the oil drains into the lube oil return oil header.

Low Pressure Jacking Oil The low-pressure (LP) jacking oil “lifts” the rotor shaft out of the bottom half of the bearing and “floats” the rotor shaft on a cushion of oil during unit startup. This makes the rotor shaft easier to “break away” and start rotating. High Pressure Jacking Oil The high pressure (HP) jacking oil “pushes” the rotor shaft off the thrust bearing pads during unit start up. This makes the rotor shaft easier to “break away” and start rotating. Jacking Oil Return The jacking oil is returned to the generator lube oil sump by the return oil header.

GENERATOR LUBE OIL OPERATION Oil supply pressure gauges and filter differential pressure gauges are located on the generator gauge panel outside the generator enclosure. Gauges, switches, and transmitters have isolation valves in sensing lines to facilitate instrument maintenance or replacement. Oil for generator-bearing lubrication and for jacking oil pump system operation is extracted from the lube oil reservoir by pumps and discharged into a common supply line. Ball valves on the pump discharge piping can isolate the pump from the common supply line. Check valves prevent oil from flowing backwards. Oil discharge pressure for each pump is monitored by pressure gauges. The pressure gauges are on the pump discharge side of the check valves to ensure that only pump pressure (not lubricating oil manifold pressure) is measured. Each pressure gauge can be isolated from the pump discharge line. Pump A (AC-powered pump) pressure switch PSL-6073A is set to initiate an alarm at pressures 50 psig(345 kPaG). Pump B (AC-powered pump) pressure switch PSL-6073B is set to initiate an alarm also at pressures 50 psig (345 kPaG). If applicable, emergency coastdown pump (DC-powered auxiliary pump) pressure switch PSL-6074 initiates an alarm at pressures 20 psig (138 kPag).

Oil flow from the common supply manifold is routed to either (1) the lube oil heat exchanger and then the duplex filter, or (2) directly to the duplex filter (bypassing the heat exchanger assembly). Flow to and through the shell-tube heat exchangers, or flow around the heat exchangers, is controlled by thermostatic, 3-way control valve TCV-6065. This thermostatic control maintains an oil outlet temperature of 140 F (60 C). If the oil temperature is > 140 F (60 C), the thermostatic valve modulates closes and varies the oil flows through the heat exchanger. The common supply line divides to supply lubrication simultaneously to the two generator bearings as well as through the gearbox. Oil flow to the bearings is through check valves and orifices and for the exciter-end and drive-end bearings, respectively. The check valves prevent oil backflow into the lube oil system during jacking oil pump operation. Temperature elements TE-6023 and TE-6021 are installed in the exciter-end and drive-end bearings, respectively. Each element monitors the bearing temperature and transmits these values to the control system. The control system initiates a high-temperature alarm at 197 F (92 C) and initiates a FSLO system shutdown at 203 F (95 C). Temperature elements TE-6035 and TE-6036 are installed in the exciter-end and drive-end bearing drain lines, respectively. Each element monitors bearing drain oil temperatures and transmits these values to the control system. The control system initiates a hightemperature alarm at 189 F (87 C) and initiates a FSLO system shutdown at 194 F (90 C). Temperature indicators TI-6012 and TI-6011, scaled 50400 F (10-200 C), indicate the bearing oil discharge temperatures for the exciter-end and drive-end bearings, respectively.

Extensions of the lube oil supply lines to the generator bearings supply oil to fill two generator lube oil rundown tanks that are designed to hold 20 gallons (76L) each. Mounted near the generator housing, the rundown tanks are positioned so that oil from the tanks flows by gravity into the lube oil supply line. In the event of AC pump failure (or during emergency shutdown with the DC pump operating), oil from the rundown tanks is supplied to the bearings through snubber orifices. During operation, the tanks are maintained at capacity through the same oil supply lines. Each rundown tank has a level switch: LS-6041 and LS-6042. If oil level in any tank is lower than 6 inches (152 mm) from the top of the tank, the associated level switch notifies the TCP. If the low level occurs 5 minutes after startup, the control system will abort the startup. If the low level occurs during operation at normal speeds, the control system will initiate an alarm. Lubricating oil flows through the generator bearing assemblies, then drains by gravity to the generator lube oil reservoir. An oil flow indicator is located in each generator bearing drain line for visual verification of oil flow through the bearings.

Generator Jacking Oil Pump Pressure gauges are located on the generator jacking oil gauge panel outside the generator enclosure wall. The pressure switches are located on the MGTB with the generator lube oil switches and transmitters. Gauges and pressure switches have isolation valves in sensing lines to facilitate instrument maintenance or replacement. Check valves prevent backflow of oil into the pump elements. For jacking oil pump maintenance purposes, it is necessary that the main AC lube oil pump be in operation. The four elements of the jacking oil pump take supply oil from the generator lube oil system, just downstream from the duplex filter. Inlet pressure may be monitored on jacking oil pressure indicator PI-6052. Jacking oil is drawn through a pump isolation valve and a four-branch manifold via a 2-inch pipe to the four-pump suction inlets. Pump inlet pressure is monitored just downstream from the pump isolation valve by pressure switch PSL-6050, which closes to initiate an alarm if jacking pump inlet pressure is 10 psig (69 kPag), while pressure switch PSLL-6051 closes to initiate a FSLO shutdown if the jacking oil inlet pressure is 5 psig 34 kPaG). As part of the system startup logic, the contacts of switch PSL-6050 must be open before the control system startup permissive requirements are satisfied.

The outlet pressure of the low-pressure pump elements is limited to 1000 psig (6895 kPaG) by pressure-relief valves PSV-6053A and PSV-6053B, and the outlet pressure of the high-pressure pump elements is limited to 3000 psig (20864 kPaG) by pressure-relief valves PSV-6054A and PSV-6054B. Discharge from the pump elements is routed through four ½ x ¾ -inch pipes, check valves, and 5 , absolute, no-bypass filters to the generator bearings. The check valves prevent backpressure from normal generator lubrication pressure when the jacking oil pump is not operating. Four gauges display the output pressures of the four pump segments. Snubber orifices help prevent gauge damage by an unexpected, sudden application of pressure. Gauges PI-6046 and PI-6049 monitor the low-pressure pump outputs and are scaled 0–1500 psig (0-10342 kPag). Gauges PI-6047 and PI-6048 monitor the high-pressure pump outputs and are scaled 0–5000 psig (34474 kPaG).

Generator Lube Oil Reservoir The generator lube oil reservoir has a 2640-gallon (9995 L) retention capacity (3000 gallon (11356 L)capacity of mineral lubricating oil). The reservoir is filled via a fill cap and basket strainer, and may be drained via a 2-inch drain valve. A plate-frame heat exchanger cools the lube oil before it enters the air-oil separator. The air-oil separator (demister), driven by a 3 -hp, 400 VAC, 3phase, 50-Hz motor, allows entrained air to escape to the atmosphere while capturing oil droplets that are drained to the reservoir. Pressure indicator PI-6088 monitors reservoir pressure from the top of the reservoir. Demister pressure switch PSH-6089 closes at –1 inch (-25 mm) of water increasing and activates an alarm. Level gauge LG-6068, located on the side of the tank, provides for direct observation of oil levels in the tank. The tank heater is comprised of thermostatically controlled elements HE-6067A and HE-6067B and switches TC-6077 and TSL-6020. The heaters warm the oil during cold-weather operation. The control switch energizes the heaters, as required, to maintain the temperature at 90 F (32 C). Temperature switch TSL-6020 signals the control system to initiate an alarm when oil temperature drops to 70 F (21 C). Alarm switch LSL-6001 signals the control system to initiate an alarm and deenergize the lube oil heaters whenever the oil level drops 12 inches (305 mm) below the flange. Thermometer TI-6014, scaled 50400 F (10-200 C), measures actual lube oil temperature in the reservoir.

A differential pressure gauge and switch warn operators of a dirty filter element. The instruments may be isolated from the system by instrument valves. A differential pressure-balance valve permits the equalization of pressure across the instruments. Differential pressure gauge PDI-6007 indicates filter differential pressure in a range of 0–30 psid (0-207 kPaD), and differential pressure switch PDSH-6015 signals the control system to initiate an alarm if the pressure drop across the oil filter increases to 20 psid (138 kPaD).

LM6000 Turbine Control System (Woodward Control)

The turbine-generator control system detects turbine engine and generator parameters; responds to operator directions; and performs fuel management, startup, shutdown sequencing, and electric power generator synchronization. The unit also senses unsafe conditions, generates operator alarms, and shuts down the engine when necessary to avoid danger to personnel or equipment. Starting and stopping the gas turbine engine or changing its modes of operation must be accomplished in a sequence that considers engine reliability and personnel safety. Prior to startup, ventilation fans and lube oil pumps must be in operation, engine and starting subsystem status must be verified, and operator mode selections and start authorization must be given. After startup has been initiated, fuel system initialization must proceed ignition and warm-up intervals must be satisfied before the engine is permitted to accelerate. Synchronism to the electric utility feed bus must then be established and the generator output circuit breaker closed. These sequential operations are all controlled by the turbinegenerator control system. The MicroNet control system implements Woodward’s real time operating system. The control is based on a 5 millisecond interrupt (the Minor Frame Timer or MFT). The operating system schedules application tasks and control algorithms at the beginning of each MFT. In the application program each part or function of the application is executed in a scheduled multiple of the MFT called a rate group, or RG. In this manner, all tasks or control functions are implemented exactly at a scheduled time, which allows for accurate and consistent control dynamics. The tool used to develop this program is the Graphical Application Program (GAP). GAP is a Woodward developed Windows based program that uses standard blocks to develop an application.

The MicroNet Chassis is designed around a modular six slot chassis (block). Each block consists of a pre-molded cage with a fan for cooling and a temperature switch for high temperature detection. A forced air-cools the chassis, and either a module or module blank must be installed in every slot to maintain correct airflow. The fans run whenever power is applied to the system. The Simplex twelve slot MicroNet control utilized in this system, is composed of three blocks with a motherboard inserted in the back of the assembly to make connections between the fans, switches, power supplies, and control modules.

INPUTS AND OUTPUTS The MicroNet platform is developed around the VME chassis and the CPU module that goes into the first active slot of the VME chassis. All I/O modules plug into the remaining slots of the VME chassis. Expansion chassis can be used to allow additional I/O modules. Each I/O module has connectors on the faceplate. For analog and discrete I/O, cables connect to the module to a Field Terminal module (FTM). The FTM is used to connect to the field wiring. For communication modules, FTMs are not used. Cables are connected directly to the faceplate of the communications module. The following diagram shows the flow of analog and discrete inputs from the field to the application.

MICRONET SIMPLEX POWER SUPPLIES The MicroNet Simplex control may use either single or redundant power supplies. A motherboard located on the back of the chassis allows the two power supplies to form a redundant power system providing: •Two separately regulated, 24 Vdc, 12 A outputs, •Two separately regulated, 5 Vdc, 20 A outputs •Two separately regulated, 5 Vdc precharge outputs to the control. Power output regulation, including line, load, and temperature effects, is less than ± 5%. When redundant power supplies are running, current sharing circuitry balances the load to reduce heat and improve the reliability of the power supplies. In the event that one supply needs replacement, this feature also ensures hot replacement of the power supplies without disrupting the operation of the control. Each main power supply has four LEDs to indicate power supply health •OK •Input Fault •Overtemperature •Power Supply Fault

FUEL CONTROL SYSTEM SCHEMATIC WALK THROUGH The fuel valve position is driven by the output of the two low signal select (LSS) buses, whichever is lowest. For example, if the start limiting signal at LSS (2) is at a lower value than the output of bus (1) or the deceleration limit or fuel flow limiting signal into bus (2), the start limiting signal will control the fuel valve. As the start limiting signal increases, one of the other inputs will control the fuel control valve position. Typical of the inputs to LSS bus (1) is the XN25 control signal. The XN25 speed and reference signals are illustrated as inputs to an operational amplifier configured as a comparator. The comparator output will remain positive unless the XN25 speed signal increases above the reference value. System sequencing logic, under operator direction, establishes the start limiting and the XN25 and XNSD reference signals as biased by safety conditions. Limiting inputs from T48, PS3, and T3 control fuel to prevent engine damage, compressor stalls, or flameout conditions. The limiting inputs are derived from transfer functions based upon engine operational design parameters.

XN25 SPEED REFERENCE LOGIC DIAGRAM Voltage from the XN25 reference ramp is raised or lowered under software control. High-pressure compressor discharge temperature is compensated for standard temperature variations (T2 = 59° F [15 C]) and applied as a bias to the reference ramp output, to obtain the XN25 reference input value.

XNSD SPEED REFERENCE LOGIC DIAGRAM Two modes of control are provided: isochronous or parallel mode. In the isochronous mode, XNSD speed is maintained at 3600 rpm, with allowance for droop as load increases. In the parallel mode, power obtained from load current and voltage is summed with the output of an XNSD reference ramp. The resulting XNSD reference is stabilized when loading is driven to equal the set point reference. Set point control is established manually or automatically from operator-loading selections. (See Sequencing Logic section.)

PS3 LIMITING CONTROL LOGIC The higher of the two PS3 sensors (A or B) is compared with the PS3 set point as biased by LPC inlet temperature T3. The influence of the T2 bias at values below 48° F (9 C) is negative, whereas at temperatures above 48° F, the T2 bias is positive. The bias is implemented to prevent engine damage caused by high PS3 values and to improve performance at higher HPC inlet temperatures.

The influence of the T2 bias prevents T3 from exceeding values that would affect engine reliability. As T2 decreases, T3 is limited to lower values because of the air mass increase at lower temperatures.

GE Energy PREOPERATION PROCEDURES Applying Alternating-Current Power During Downtime

Alternating-current (AC) power (normally commercial power) is required for certain functions, such as lighting and heating, and for maintenance purposes while the turbine generator is not running. To apply AC power for specific power needs during downtime, or in preparation for startup, perform the applicable portions of the following procedure. 1.

Ensure that no repair work is being performed on bus or connected circuitry.

2.

Close utility circuit breaker to apply AC power to cogeneration bus.

3.

Close utility circuit breaker to apply AC power to the cogeneration bus.

4.

6.

Turn on lights and systems, as required, on lighting and power distribution panel, and turn on space heaters as dictated by ambient temperature conditions.

7.

Check oil levels in turbine and generator lube oil reservoirs. Add oil as necessary to restore specified levels. Use only approved oils for turbine and generator lube oil systems.

Check fluid level in hydraulic start unit reservoir. Add fluid as necessary. Set cubicle circuit breaker handles to On position for all lubrication and hydraulic oil tank heaters, space heaters, and generator stator core heater. Check that lubricating oil temperatures are more than 70 °F (21 °C).

PRESTART INSPECTIONS This procedure consists of a series of mechanical inspections and corrections, as necessary, to ensure the GTG set is in condition for safe and effective startup and operation. General Mechanical Inspections If maintenance has been performed on the inlet air filter, replace panel filters or barrier filter elements that were removed for maintenance. If maintenance has also been performed on the air filter or turbine air inlet, obtain access to inlet plenum and inspect for cleanliness. Remove any foreign objects or debris. Ensure all filter house doors are securely closed.

Slide 6

LM6000 Sequences

Because of variations in operating conditions, as well as differences in hardware, “normal” indicator readings vary between GTG sets. For this reason, it is important that the equipment be monitored frequently during the first 30 – 90 days of operation so that performance trends can be recorded and maintenance requirements predicted. Toward this end, regular monitoring intervals should be set up for recording all instrument readings while the generator is in operation. These data should be continuously compared to the established trend, and adjustments should be made as necessary to ensure that readings stay within acceptable limits and the generator rating is not exceeded.

OPERATING PROCEDURE SELECTION Insofar as is practical, these operating procedures are presented in a progressive sequence from preparation for startup through shutdown. In addition, service and maintenance functions are deferred to O&M section SP-M016, Control System/Operator Interfaces.

Shutdown may be initiated by operator selection or caused by engine operational conditions at any time during startup or running operational modes. The LM6000 software code lists more than 130 engine, generator, and subsystem conditions that can cause a shutdown.

The five programmed shutdown sequences that can occur once shutdown is initiated are: 1)

Fast-Stop Lockout without Motoring (FSLO)

2)

Fast-Stop with Motoring (FSWM)

3)

Cooldown Lockout (CDLO/NORMAL)

LM6000 Sequences

GE Energy Fast-Stop Lockout without Motoring (FSLO) An FSLO automatically initiates the following actions: •

Fuel valves (and water or steam valves, if applicable) are closed

•

The unit breaker is tripped open.

•

Variable inlet guide vanes are closed.

• Variable bleed valves doors are opened (closed later during coast down). •

Ignition system and starter are deenergized.

•

XN2, XN25, XNSD and oil pressure alarms are bypassed.

•

Four hour lock-out if problem cannot be corrected in ten minutes.

When these steps are completed, drain and vent valves are opened, alarms, interlocks, and start sequence timers are reset, and the operating time meter is turned off. Fast-Stop with Motoring (FSWM) An FSWM automatically initiates an FSLO, and then the starter is engaged for 25 minutes when XN25 reaches 1700 RPM.

LM6000 Sequences

GE Energy Slow Decel to Minimum Load (SML)

A slow decel to minimum load (min-load) is a controlled deceleration at a rate that allows all engine schedules and engine cooling to be maintained at a controlled rate. Rather than decel all the way to core idle, the engine decels to the min-load point. This allows the condition to be investigated without requiring a shutdown. An SML automatically initiates the following actions: •

Fast load shed to minimum load in 20 seconds.

•

If the problem still exists after 3 minutes then do a CDLO.

NOTE:

If on naphtha fuel, SML is replaced with FSWM.

Step Decel to Idle (SDTI) A step-decel to idle is an immediate rapid (max decel rate) deceleration to idle followed by a 10-second pause, and then by a shutdown. A step-decel provides a more controlled and orderly way of shutting down the engine than does an immediate shutdown at power. The 10-second delay pause at core idle allows various scheduled engine systems, such as variable inlet guide vanes (VIGV’s) and variable bleed valves (VBV’s), to reach a stabilized condition before shutdown occurs.

GLOSSARY A A/D Conversion – Analog-to-Digital Conversion: A con-version that takes an analog input in the form of electrical voltage or current and produces a digital output. ABT – Automatic Bus Transfer: For critical loads, normal and alternate, power sources are provided. The power sources are supplied from separate switchboards through separate cable runs. Upon loss of the normal power supply, the transfer switch automatically disconnects this source and shifts the load to the alternate source. AC – Alternating Current: Alternating current is an electric current that flows first in one direction for a given period of time, and then in the reverse direction for an equal period of time, constantly changing in magnitude. A – Ampere: A unit of electrical current or rate of flow of electrons. One volt across one ohm of resistance causes a current flow of one ampere.

Because shore power is an infinite bus, droop mode is necessary to control the load carried by the gas turbine-generator set. If a gas turbine-generator set is paralleled with shore power, and one attempts to operate in isochronous mode instead of droop mode, the gas turbine-generator set governor speed reference can never be satisfied because the gas turbinegenerator set frequency is being held constant by the infinite bus. If the gas turbine-generator set governor speed reference is above the shore power frequency, the load carried by the gas turbine-generator set will increase beyond capacity in an effort to raise the shore power frequency. If the speed reference is below the shore power frequency, the load will decrease and reverse in an effort to lower the shore power frequency. The resulting overload or reverse power will trip the gas turbine-generator set circuit breaker.

Bernoulli theorem As a fluid flows through a restricted area such as a nozzle, the velocity of the fluid will increase with a corresponding decrease in pressure and a slight decrease in temperature. The inverse is true for fluid flow through a diffuser. Boyle’s law If the absolute temperature of a given quantity of gas is held constant, the absolute pressure of the gas is inversely proportional to the volume the gas is allowed to occupy. Brayton cycle The thermodynamic cycle on which all gas turbine engines operate, considered to be a constant pressure cycle (combustion occurs at a constant pressure). British thermal unit Btu Defined as the quantity of heat required to raise the temperature of a 1-pound mass of water 1 degree Fahrenheit (1° F). (Water is to be pure distilled water, and the temperature change is from 64 degrees Fahrenheit (64° F) to 65 degrees Fahrenheit (65° F).) Cascade effect As related to compressor stall, cascade effect is where turbulence created in the forward stages of the compression section is passed rearward through the compressor, with an increase in the total amount of turbulence with each successive stage. Celsius (centigrade) °C Normally used by scientists, a temperature scale in which the temperature θc in degrees Celsius (°C) is related to the temperature Tk in kelvins by the formula: θc = Tk − 273.15. Charles’ law If the absolute pressure of a given quantity of gas is held constant, the volume the gas is allowed to occupy is directly proportional to the absolute temperature of the gas. Compound blading A blending of both reaction and impulse turbine blading such that the actual blades are impulse at the root and reaction at the tip. It is the most common type of blading used in the turbine and power turbine sections of modern gas turbine engines. Compressor discharge pressure CDP The actual pressure of the air exiting the compressor section, after having passed through all stages of compression and the diffuser, and passing on to the combustion section. Compressor discharge temperature CDT The temperature of the compressed air that has passed through all compression stages and the diffuser, and is being passed to the combustor.

Compressor inlet temperature CIT The temperature of the air which actually enters the compressor. Normally measured at the inlet bellmouth. Compressor stall When turbulence across the stages of the compressor becomes severe enough (owing to the cascade effect), the actual airflow through the compressor is disrupted and decreases. During compressor stall, it is not common to see a reduction in the rpm of the compressor section, only a reduction in the actual air- flow through the compressor.
