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.

GE Aero Package Training Course Introduction

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.

GE Aero Package Training Course Introduction

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-000-00-00-000-01

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.

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.

Annular Type Combustor

Slide 16

gGE Energy

TM2500+ Gen VI Package Familiarization

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.

TM2500+ Gen VI Package Familiarization

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. This configuration is found in the LM1600 and the LMS100.

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-000-10-10-000-00

BEARINGS AND SUMPS Bearings are classified into two broad categories; friction and anti-friction. The gas turbine utilizes anti-friction type bearings, whereas the generator has friction type bearings. Seven anti-friction roller and ball type bearings support the rotating components and the aerodynamic loads on the LM2500+. The bearings are held together with a cage and race assembly and, by design, the bearings do not generate significant heat from friction. They do, however, absorb heat transmitted from the engine’s hot-gas path and because of this, lube oil is supplied to the bearings for cooling purposes. The roller bearings support radial loads and axial thrust loads are supported by ball bearings. These bearings are located in the sumps A, B, C, D areas.

Synthetic lube oil is supplied to the bearings and scavenged out of the sumps by a seven (7) element pump assembly which is mounted on the accessory gearbox. 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, gearboxes, and the air/oil separator. 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, and then oil is scavenged through the transfer gearbox. The No. 4R/4B and No. 5R/6R bearing zones of sump-B and sump-C are individually scavenged, as is the No. 7R bearing zone of sump-D. All sumps emit oil mist-carrying air that is vented to an air-oil separator which is mounted on the front side of the AGB. The oil is then scavenged from the separator and the air is vented to the exhaust diffuser.

Variable Vanes • The Inlet Guide Vanes (IGV’s) and next 7 stages of vanes are called Variable Stator Vanes, or VSV’s. These vanes are all mechanically ganged together, and will change their angular pitch in response to a change in compressor inlet temperature or a change in gas generator speed. The purpose of this is to provide stall-free operation of the compressor through-out a wide range of speed and inlet temperatures. F-025-10-10-101-00

HPTN1 Cooling • Impingement, convection and film cooling circuits within each individual HPTN1 vane are supplied with high pressure cooling air directly from the compressor discharge chamber. • To distribute the cooling flows, inserts are installed into forward and aft cooling chambers machined into the vanes. • High pressure air from the compressor discharge chamber enters the forward insert through the underside of the HPTN1 forward inner seal. F-025-10-10-101-00

• Holes in the insert impinge the high pressure air directly against the inner walls of the forward chamber, displacing hot air, and providing a continuous supply of cool air to absorb heat directly from the metal structure of the vane. • Hot air displaced by the impingement flow is carried out of the vanes through nose holes by convection. • Gill holes in side of the vane maintains a thin layer of film cooling air between the metal structure of the vane and the hot combustor discharge gases.

TM2500+ Gen VI Package Familiarization SYNTHETIC LUBE OIL SYSTEM

General The LM2500+ turbine is lubricated by an internal pump and lubrication system described in GE publication GEK-105054. GE AE provides an external lube oil system to filter, cool, and de-aerate the lube oil discharged from the internal system. The external system is fed by a scavenge pump, which is driven by the turbine accessory gearbox whenever the turbine gas generator is rotating. Purpose The synthetic lube oil (SLO) system functions to prevent damage to the high-pressure (HP) and low-pressure (LP) rotor bearings and sumps as well as the inlet transfer gearbox (TGB) and accessory gearbox (AGB). The SLO system also provides oil for operating the actuators for the variable stator vanes (VSVs) and lubrication to protect the over-running clutch for the hydraulic starter motor.

Instruments and Controls Lube oil pressures and temperatures at critical points are transmitted and displayed on the desktop HMI. Gauges and pressure transmitters in the system have been installed with a needle valve in the instrument sensing line to permit replacement and calibration without disturbing the lube oil flow. The system piping has been provided with manually operated ball valves to isolate components for repairs and maintenance.

System Operation Refer to Flow & Instrument Diagram (F&ID) XXXXX-751244, Turbine Lube Oil System. System operation for the GTG set is as follows:

The internal turbine lube oil pump draws lube oil from the 150-gallon reservoir through the check valve and inlet port L1. Oil passes from discharge port L2 2 to the lube oil supply filter assembly in the external system. Differential pressure on the supply line filter is monitored by transmitter PDT-1006, which sends a 4-20 mA signal the electronic-turbine control system. Pressure differential indicator PDI-1006 displays the filter differential pressure at the operator screen as well as locally at the turbine gauge panel. When differential pressure across the filter reaches 20 psid (138 kPaD) increasing, the control system activates high alarm PDAH-1006. Manual shut-off valves upstream and downstream of the filter allow for maintenance. F-025-10-20-103-00

System Operation (cont.) Oil from the filter passes through the oil header port L4 4 into the internal lube oil system of the turbine for distribution to the accessory gearbox and the turbine shaft bearings. Internal sensor TE-1028 (drawing sheet 2) activates an alarm if the temperature of the incoming oil reaches 200 °F (93 °C) increasing. Other internal sensors, TE-1023, TE-1024, TE-1025, TE-1026, and TE-1027, monitor the lube oil temperature in the turbine-bearing sumps. These sensors activate an alarm if the lube oil temperature in any sump reaches 300 °F (149 °C) increasing, and initiate a SML shutdown if the oil temperature reaches 340 °F (171 °C) increasing. Electromagnetic chip detectors, MCD-1060 through MCD-1064 monitor lube oil for metal chips, and initiate an alarm if accumulated chips lower the detectors’ resistance to 100 ohms decreasing. Gauges and electrical devices monitor oil pressure at the header port L5 (drawing sheet 1). Transmitter PT-1021 provides the internal lube oil pressure reading to the electronic-turbine control system. Header pressure is displayed remotely by pressure indicator PI-1021. PT-1021 activates an alarm for the following conditions: · if pressure < 8 psig and if 4500 < ngg < 8000 · if pressure < 25 psig and ngg ≥ 8000 rpm PT-1021 activates an FSLO shutdown for the following conditions: · if pressure < 6 psig and if 4500 < ngg < 8000 · if pressure < 15 psig and ngg ≥ 8000 rpm F-025-10-20-103-00

System Operation (cont.) Oil drawn from the bearing sumps by the scavenge stage of the turbine pump passes through scavenge oil discharge port L3 to the scavenge filter. System pressure is monitored remotely by PI-1022 upstream of the scavenge filter. Transmitter PT-1022 forwards pressure signals to the electronic-control system which activates alarm PAH-1022 if the scavenge oil pressure rises to 110 psig (758 kPaG) increasing. Pressure differential transmitter PDT-1007 monitors differential pressure across the scavenge filter and forwards signals to the electronic-control system. The control system activates alarm PDAH-1007 when the pressure differential reaches 20 psid (138kPaD) increasing. . Relief valve PSV-1003, located near the scavenge oil filter inlet, prevents the scavenge system pressure from exceeding 140 psig (965 kPaG) by returning excess oil to the reservoir. Otherwise, oil from port L3 is routed through the scavenge lube oil filter assembly, on its way to the fin fan heat exchanger Cooled oil from the heat exchanger is returned to the lube oil reservoir for recirculation. The portion of oil actually routed through the selected cooler is determined by 3-way, thermostatic control valve TCV1001. This valve apportions oil flow through the cooler, as required, to maintain the outlet temperature at < 140 °F (60 °C). When lube oil temperature is low, such as at the start of turbine operation, the thermostatic valve bypasses the oil flow around the heat exchanger to the reservoir. As the lube oil temperature increases during turbine operation, the valve progressively directs more oil through the heat exchanger until, at 140 °F (60 °C), nearly all the oil flows through the heat exchanger. The filtered and cooled scavenged oil returns to the lube oil reservoir, where air and other gases are vented to the atmosphere through the reservoir demister/flame arrestor. F-025-10-20-103-00

System Operation (cont.) Reservoir oil temperature is maintained at 90 °F (±8 °F) by an integral thermostatic switch TC-1004 and immersion heater HE-1004. A level gauge LG-1000 permits direct (local) observation of the reservoir oil level, while level transmitter LT-1002 forwards signals to the control system for remote monitoring. The control system activates low alarm LAL-1002 when the oil level drops to 9 1/2" (241) or below (as measured from the bottom of reservoir). The control system also activates high alarm LAH-1002 when the oil level rises 18" (457) or above. Temperature element TE-1013 monitors the temperature of the lube oil in the reservoir and forwards signals to the control system. The control system activates alarm TAL-1013 if the oil temperature falls to 70 °F (21 °C) or below.

VARIABLE GEOMETRY OVERVIEW The LM2500+ variable geometry (VG) system is designed to allow precise control of air flow through the turbine under all operating conditions, in order to achieve a high degree of efficiency, stall-free safety and operational flexibility. Variable stator vanes (VSV) help control air flow during various turbine speeds. While stator vanes are designed for peak aerodynamic efficiency at full speed, they must also be able to function efficiently at part load and reduced speed. At lower speeds the final stages of the compressor can’t ingest the volume of air compressed by the earlier stages, and the variable stators can be positioned to limit the amount of air handled by the first stages of the compressor. As speed increases, the variable stator vanes gradually open until they are fully open at full turbine speed.

The high pressure compressor (HPC) is comprised of 17 stages (numbered 0 through 16). The inlet guide vanes and the next seven stages (Stages 0 – 6) comprise the components referred to as the variable stator vanes. These vanes are mechanically ganged together and their pitch can be changed as needed during turbine operation. Pitch of the blades is changed in response to changes in compressor inlet temperature (T2) or gas generator speed (NGG).

ACTUATORS The variable vanes are connected to two actuators (3:00 & 9:00) via a pair of torque shafts. When operated by the individual actuators, the torque shafts operate the variable guide vanes through actuation rings and linkages. The integral linear variable differential transformers (LVDT’s) are the feedback type in which the movement of the actuators is used to provide a feedback signal to the VSV control.

PUMP Oil from the turbine oil system is delivered to the VG pump located on the accessory gearbox. The VG hydraulic pump is a fixed-displacement design which supplies pressurized lube oil to the servo-valve assembly for delivery to the actuators. The hydraulic pump/servo-valve houses a motor-positioned hydraulic servo for porting fluid at regulated pressures. All return flow is bypassed back to the high pressure side of the gas turbine lube oil pump, and the VSV servo-valve will close the VSVs in the event of a failure of the hydraulic pump.

VSV CONTROL The VG control system consists of the VG hydraulic pump and an electrohydraulic VSV servovalve assembly. The hydraulic pump/VSV servovalve houses a torque motor-positioned hydraulic servo for porting fluid at regulated pressures, and two VSV actuators with integral linear-variable differential transformers (LVDT’s) to provide feedback position signals to the off engine control unit. The VG pump provides hydraulic flow to the head- and rod-ends of the VSV actuators. The actuators are positioned in response to compressor inlet temperature (T2) and gas generator speed (NGG). For any one temperature and any one speed, the VSVs take one position and remain in that position until the NGG or T2 changes. Positioning of the inlet guide vanes (IGV) and VSV’s is scheduled by packager-supplied control system electrical input to the servovalve, mounted on the VG hydraulic pump. Position feed back to the control is provided by LVDT’s from the VSV actuators.

HYDRAULIC START SYSTEM The hydraulic start system turns the engine and is capable of starting it, fuel purging, water washing, cool down, and conducting maintenance. The hydraulic start unit is located on the auxiliary skid and consists of a reservoir, filters, heat exchanger, charge pump and motor, junction box, and a hydraulic starter motor mounted on the starter drive pad of the turbine auxiliary gearbox. This hydraulic starter motor turns the engine. Two operating speeds are provided: a low speed for water washing and maintenance, and a high speed for turbine starting and fuel purging. Engine speed can be controlled automatically from the DCS. Transmitters located on the auxiliary skid allow for monitoring of the hydraulic charge pump and main system pressures, temperatures, and fluid levels on the DCS monitor. Local gauges PI-6009 and PI-6012 are also provided on the auxiliary skid for troubleshooting purposes. Additional details on the hydraulic start system can be found in engineering drawings. This section provides an overview of the hydraulic start system.

Hydraulic Start System Operation (Refer to F&ID xxxxxxx-751232 Hydraulic Start System) Hydraulic fluid is drawn from the reservoir by the charge pump. The charge pump replenishes the main, closed-loop start system with hydraulic fluid at 350 psi (2413 kPaG). The main pump increases the hydraulic fluid pressure to 5200 psig (35853 kPaG) and delivers the pressurized fluid to the hydraulic starter motor at approximately 56 gpm (212 L/min).

Discharge from the hydraulic starter motor is routed back to the hydraulic reservoir through filter and cooler assemblies. Filters remove particles ³ 10 μ. The cooler removes heat generated during starter motor operation.

Power from the MCC lighting-and-distribution panel is applied to the power supply for the hydraulic start unit.

The hydraulic start system is automatically controlled. The solenoid operated valve SOV-6019 for the pump-control piston and the MCC unit starter are controlled by electronic systems at the TCP.

Reservoir Hydraulic fluid is stored in a 40-gal (182 L) stainless steel tank equipped with sight level gauge LG-6020, temperature element TE-6003, fluid-level transmitter LT-6001, thermostatically controlled immersion heaters HE-6010 and TC-60101 and a 200-mesh, hydraulic pump suction strainer with an integrated bypass valve. During turbine engine operation, hydraulic fluid is drawn from the reservoir through the strainer and the supply shutoff valve, and flows into the charge pump. Should the hydraulic pump strainer become obstructed with differential pressures ³ 3 psid, (20.7 kPaD) hydraulic fluid will bypass the filter element to prevent damage to the filter assembly. The supply line is monitored by pressure indicator PI-6000 located between the supply shutoff valve and the charge pump.

Hydraulic Oil Charge/Main Pump Assembly Hydraulic Oil Charge Pump The charge pump is one of two 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 gpm (45 lpm) to the charge pump filter. The charge pump also replenishes lost fluids in the hydraulic pump case and in the main pump, closed-loop hydraulic system. Excess hydraulic pump case supply oil is routed to the hydraulic reservoir through an inline relief valve, set to open at 25 psid (172 kPaD). From the charge pump, hydraulic fluid flows through the charge pump filter assembly and into the main pump, where the hydraulic fluid is pressurized for the starter motor loop. Charge Pump Filter The charge pump filter is a “spin on” type single stage filter. The filter has no 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).

Hydraulic Oil Charge/Main Pump Assembly Main Hydraulic Oil Pump The main hydraulic starter pump, located on the auxiliary module, is driven by a three-phase, constantspeed, 200 horsepower, 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.

LOW PRESSURE RETURN and COOLER LP RETURN FILTER Hydraulic oil returning from the starter to the suction side of the auxiliary skid pump is routed through a low-pressure return filter. The filter is a 10 micron, “spin-on” type double element filter with a 25 psi bypass circuit and differential pressure indicator. After leaving the LP return filter, hydraulic oil flows back to the suction side of the auxiliary skid hydraulic pump. CASE DRAIN FILTER Hydraulic oil returning from the starter’s case drain is routed through a case-drain return filter. The filter is a 10 micron, single element filter with a 25 psi bypass circuit and differential pressure indicator. After leaving the case drain filter, hydraulic oil flows through a heat exchanger and then returns to the auxiliary skid hydraulic oil tank. HEAT EXCHANGER The heat exchanger is an air/fan cooled unit that enables extended cranking capability for cool-down cycles without exceeding temperature limits. An electric motor-driven fan cools hydraulic oil returning from the starter and the discharge from the heat exchanger is routed directly to the hydraulic reservoir. The 3 HP motor is dual rated at 380/460 VAC. The temperature of the hydraulic fluid is monitored by high-temperature element TE-6002. If the temperature is ³ 180 °F (82 °C), the control system will activate an alarm.

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.

Gas Purge When running on natural gas, fuel gas is used to purge the primary and secondary liquid fuel manifolds and nozzles. Gas is bled from the fuel system downstream of shut-off valve FSV-2004 through a 3/4” line where it passes through a check valve and enters the feed lines to either the primary or secondary liquid fuel manifold. SOV-2013 can stop purge gas from entering the secondary manifold if water injection is to be used for NOX abatement.

***NOTE*** - During operation, fuel supply can be transferred from gas to LQ or LQ to gas at full load if the permissives are met. The process takes approx. 20 seconds for full transfer. Exhaust Collector Drain Significant amounts of flammable liquids and water wash solution may accumulate in the turbine exhaust collector. The exhaust collector drain system eliminates these accumulations to ensure safe starts. During operation, air pressure to close FCV-2005 comes from the 9th-stage bleed-air manifold and, as turbine speed increases, positive pressure developed in the exhaust collector forces the condensate accumulations out through FCV-2005, a check valve, and the fuel drain valve to customer connection [7]. As the turbine speed continues to increase, 9th-stage bleed air increases. When the pressure rises to 50 psig, FCV-2005 closes. The collector drain remains closed during normal operation.

COMBUSTION AND VENTILATION AIR SYSTEM (Refer to F&ID xxxxxxx-751239 Ventilation and Combustion Air System) The combustion and ventilation air system of the MGTG (mobile gas turbine generator) set supplies filtered combustion air for turbine engine operation, filtered ventilation air for the turbine enclosure, and filtered ventilation air for the generator. The air filter module supplies clean combustion air to the gas turbine and clean ventilation air to the turbine enclosure, and the generator is equipped with a separate ventilation system that includes inlet filters, exhaust silencer, and pressure and temperature sensors.

Turbine Enclosure and Combustion Airflow Gas turbine engine suction draws clean, filtered air through the air filter for turbine combustion, while ventilation fans force clean, filtered air through the turbine enclosure. Airflow is in two separate streams:

Combustion air flows through a plenum and an FOD screen to the gas turbine engine. Combustion airflow, at a nominal rate of 150,000 scfm (4248 scmm), enters the turbine engine where it is mixed with fuel and burned in the combustor. Ventilation airflow drawn by the ventilation fans at a nominal rate of 17,500 scfm (496 scmm), enters the turbine compartment where it circulates around and cools mechanical components. Two ventilation fans are provided, one active and one on standby. Ventilation air, having exchanged heat with the mechanical components, is drawn out through the enclosure wall and expelled through the exhaust assembly. The control system activates differential pressure alarm PDAL-4007 when pressure differential reaches 0.1” (2.5 mm) Wg increasing/decreasing (determines eductor or fan mode).

Filtration 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 (high efficiency filter) consist of a minipleat element.

Fire Dampers The ventilation fans have CO2 activated dampers that close in the event of fire. Should a fire occur these dampers automatically seal the turbine enclosure, thereby eliminating the oxygen required for combustion. Sensors ZSC-4266A and ZSC-4266B monitor ventilation damper position, and initiate an alarm in the closed position. A bypass damper is provided to increase flow area so that an eductor can pull more air when the ventilation fans are turned off. Both the bypass dampers and the filter dampers are used while operating in eductor mode F-025-10-20-401-00

Space heaters are provided in the base of the generator and the exciter.

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. Performing thorough water washes with high quality ingredients on a regular basis with help combat these conditions.

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.

GE Energy

TM2500+ Gen VI Package Familiarization

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 valve controls and a local Start switch will operate the pump, based upon operator mode selections and engine safety permissives.

Description of Water Wash Operation The customer supplies the recommended amount of chemical concentrate (solvent) through the soap and water fill funnel and the recommended amount of water through the water inlet on the auxiliary trailer. The normal recommended chemical to water mixture is 1:4 (1 part chemical and 4 parts water), but this can change with different soap vendors. After start-permissives have been satisfied (tank level and turbine temperature), the water wash system is started at the local control box on the auxiliary trailer. Fluid from the solvent and rinse tank passes through a 100-mesh strainer before entering the intake of the motordriven pump. Pump discharge is regulated by a flow-regulating valve, then passed through flow and pressure indicator gauges and solenoid valve SOV-5032 before its routed to the turbine inlet port S1. Tank level transmitter LT-5042 monitors liquid level in the tank and forwards a 4-2- mA signal to the turbine control system. LT-5042 also provides a water wash pump start permissive. The control system initiates a pump shutdown if the level lowers to within 2" (51 mm) of the bottom of the tank. Solenoid-activated valve SOV-5032 admits wash solution to turbine inlet port S1 at a regulated 15 GPM (57 LPM) through a 40 micron filter. Wash cycles last approximately 10 minutes and, during rinsing, rinse water temperature should range between 150 °F (66 °C) and 180 °F (82 °C). After rinsing, drain and clear the tank prior to the next water washing. ***NOTE***: If the outside air temperature is < 50 °F (10 °C), the customer must add antifreeze for engine protection during cold-weather washing.

The off-line water wash (referred to as a crank-soak wash) consists of the following cycles: ·

Wash

- When the local start button is depressed, the hydraulic starter is energized and NGG is taken up to 1200 rpm where the starter will then de-energize until NGG coasts to below 200 rpm. The starter is then re-engaged, and NGG is taken back up to 1200 rpm where the starter is deenergized again, and this cycle continues until the wash tank is empty. The sequencing is all automatic and the water wash pump will engage when the hydraulic starter first engages. To stop the sequence, press the local start button a second time. ·

Soak - Allow the engine to soak for a minimum of 10 minutes.

·

Rinse - This is the same as the wash sequence, only without detergent. Typically, a wash would take 2 rinses, but this can vary with detergent vendors. Rinsing is complete when there are no bubbles coming from the exhaust drain at customer connection [7] .

·

Purge - Run the pump dry for several minutes to purge the water wash piping/manifold.

·

Dry - Within 30 minutes of completing the wash/rinse cycle, start the engine and run at idle for 5 minutes. If engine operation is prohibited during this period, motor engine for minimum 5 minutes.

VIBRATION MONITORING The vibration monitoring system for the turbine engine generator consists of sensing elements for monitoring the turbine and generator vibration during operation. These sensing elements transmit vibration signals to the TCP. For General Electric transducer-mounting arrangement, refer to GE publication GEK-97310, Operation and Maintenance Manual for General Electric LM2500 60Hz Series Gas Generators and Gas Turbines. The sensors for the vibration system consist of accelerometers that monitor turbine-casing vibration and proximitors monitoring generator-bearing vibration. Sensors also monitor the high and low rotor speeds. Accelerometers on the CRF and on the TRF monitor turbine vibration. An accelerometer interface module for each accelerometer conditions the accelerometer output signals for application to the monitor unit in the TCP. Proximitors, with shaft proximity probes, monitor shaft vibration at the generator’s drive and exciter ends.

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.

FIRE PROTECTION SYSTEM THEORY OF OPERATION The Fire and Gas Detection System is an independently powered, stand-alone system. A controller at the turbine control panel (TCP) provides audible and visual alarm signals. The panel referred to as the Fire Protection Panel (FPP), interfaces with the turbine-control system to initiate operator alarms and cause turbine-engine shutdowns when conditions warrant. Ventilation fan controls are also directed through the turbine-control system interface when fire or fire-causing conditions are detected. 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 36hour intervals. During this period the system looks at each circuit run to the manual switches, heat sensors, 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.

FIRE PROTECTION SYSTEM THEORY OF OPERATION The fire protection system utilizes thermal spot detectors and gas sensors in the turbine enclosure to detect fire, or fire-causing conditions. In the case of a fire, an emergency shutdown is initiated and fuel flow to the turbine engine is terminated. The compartment-ventilating fans de-energize and the solenoidoperated valves open to release the fire-extinguishing agent. 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. When an alarm input is received, the control panel energizes a timer to start a time-delay sequence that allows the operator to evacuate the main skid area before the extinguishing agent is released. A red emergency push button station has been provided outside the doors to the engine compartment for manually initiating alarms and releasing the fire-extinguishing agent. The fire suppression and gas detection system is interlocked with the turbine vent fans and shuts down these fans to confine the fire within the compartment. Similarly, when the gas accumulation exceeds the pre-set low explosion level (LEL), a series of events takes place. The dampers remain open and the standby fan activates in order to increase compartment ventilation and expel the gas from the compartments to the atmosphere; fuel flow continues. When the sensors detect a high explosion level (HEL) of gas accumulation, fuel flow is stopped, the dampers remain open, and the standby fan activates to expel the gas from the compartment if not already in service.

FIRE-EXTINGUISHING AGENT CO2 is used as the extinguishing agent for the main skid. The system’s CO2 is stored in two sets of bottles, main and reserve, outside the engine compartment. The CO2 bottles have been provided with solenoidoperated discharge heads. A check valve on each tank ensures the activation of one tank at a time. There is no level indicator on these bottles! They need to be weighed every six months minimum. Full weight is 300 lbs.

CO2 MANUAL BLOCK VALVES Manual operated valves located on the discharge side of the CO2 bottles. Utilized when accessing the enclosure to ensure no accidentally CO2 release in the module. The valves have an electronic position feedback to the fire protection panel. In the closed position, release of CO2 is inhibited.

***NOTE***

- Except during an actual response to a fire Alarm/Shutdown condition, if the system initiates a 36-hour 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. System does not indicate that the FPP panel is

THERMAL SPOT DETECTORS Two thermal spot detectors, located in the turbine enclosure, monitor temperatures and signal the fire control modules when the temperature reaches 450 qF (232qC).

FIRE DAMPERS (2) Each gas turbine ventilation fan has a fire damper on the inlet side of the fan that will isolate the enclosure in case of fire. The dampers are counter weighted to the close position, but are normally locked open by a mechanical actuation pin assembly. When the control system initiates a fire stop, CO2 is released to the enclosures and a portion of this CO2 releases the actuation pin assemblies and the counter weights will close the damper.

***NOTE***

- Strobe lights activate with the initialization of the FPP panel. The strobe latch-in relay is armed when a shutdown condition occurs and the fan latched-out relays are armed (CO2 discharged). In the condition where high LEL initiates a shutdown, the strobe latch-in relays are armed. The strobes cannot be turned off until the key-operated CO2 purge switch is activated and fan logic reset.

CO2 RELEASE PRESSURE SWITCHES The pressure switches are located on the discharge of the CO2 bottles, downstream of the manual block valve. One switch is activated upon discharge of the main bank of CO2. If the main bank is released and the switch is not activated, the controller will release the reserve bank. If CO2 is released manually, activation of the switch will result in a FSLO shutdown of the generator set. Set at 150 psig (1035 kPaG) - FSLO shutdown. CO2 is discharged upon the activation of dry-line discharge pressure switch PSHH-3048 typically set to 150 psig (1034 kPaG) increasing. If pressure in the line reaches 150 psig (1034 kPaG), a shutdown will be initiated. CO2 activation produces a signal at the fire protection panel that is relayed to the sequencer. The sequencer then initiates an orderly FSLO.

GENERATOR OVERVIEW The generator converts rotational shaft horsepower into electrical energy when driven by an LM2500 gas turbine prime mover. The generator is typically installed without an enclosure and there are various methods used to cool the air. The unit is bolted to the gas turbine-generator package main skid, such that the rotor is axially aligned with the power turbine. A flexible coupling through the engine exhaust connects the generator rotor to the power turbine shaft. The generator is characterized as a three-phase, two-pole brushless exciter type, with an open-circuit aircooling system. To avoid degraded performance under high-current loads or ambient temperatures, cooling has been a major consideration in the design of the generator. Bearings at the drive and non-drive ends support the rotor. The gross weight of the assembled generator is approximately 61 tons.

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 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.

6.

Pressure Oil Seals – Twin lube oil seals are mounted at the inner and outer edge of each bearing cavity. Air pressure from the shaft fans is inserted between the seals to contain the bearing lube oil.

7.

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.

Generator Frame 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. TM2500+ Generator Construction F-025-10-30-100-00

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.

STATOR CORE COMPLETES MAGNETIC CIRCUIT AROUND ROTOR

LAMINATED CORE SUPPORTS STATOR COILS

Stator Core The stator core is built into a fabricated steel frame and consists of low-loss silicon, steel-segmented stampings insulated by a layer of varnish on both sides. The stampings are divided into short sections by radial-ventilating ducts extending from the center through to the outer ends. 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.

Generator Connections The generator has three stator coils, one per phase. Standard phase and terminal numbering is shown in “A” above. Three coil terminals extend through the left side of the generator housing, near the exciter end of the frame (T1,T2,T3), and three terminals extend through the right side of the generator housing (T4,T5,T6), as shown below. The generator connects to the site equipment through Lineside and Neutral Cubicles. These cubicles contain heavy busbars to transmit the generator voltage to the load. The cubicles are mounted on the generator at the site. The Lineside Cubicle can be mounted on either side of the generator to suit the customer’s layout. 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 common, or “Neutral”, point is connected to ground through a grounding transformer, as shown in “C” above.

Lineside Cubicle 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 “short-circuit” lightning energy to ground and protect the generator if lightning should strike the grid.

gGE Energy

TM2500+ Gen VI Package Familiarization Neutral Cubicle The Neutral cubicle connects to the side of the generator 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 TM2500+ Generator Construction F-025-10-30-100-00

GENERATOR BEARINGS A pressure-lubricated journal bearing supports the rotor at the drive and non-drive ends. Thrust pads are installed between the drive-end journal and the bearing, to prevent longitudinal loads that may be imposed upon the drive turbine. The bearings are supported in fabricated steel housings, which are bolted directly to the machine ends. The bearing housings are split on the horizontal shaft centerline with the lower half forming the bearing oil sump. The bearings are of plain cylindrical design, white metal lines, and spherically seated within the end frames. Oil under pressure is fed to the bearings and distributed over the bearing surface by internal grooves. On both the 60 Hz and 50HZ generators, there are two Lube Oil Pumps. One is a mechanically driven pump attached to the generator shaft at the exciter end, and there is an auxiliary DC Pump mounted to the generator lube oil tank. Orifices in each bearing supply lines controls the bearing oil flow. Drain oil discharges into the bottom of the bearing housing from where it is returned to the lube oil system.

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.

Exciter Diode Wiring 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.

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.

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.

Lube oil storage reservoir, 150-gal (567 L) Generator-driven lube oil pump Motor-driven auxiliary DC lube oil pump Lube oil filter assembly Heat Exchanger

To prevent damage, the generator bearings must be lubricated whenever the generator rotor shaft rotates. Thus, lubricating oil must be supplied to the bearing assemblies during startups, at operational speeds, and while the rotor shaft coasts to a stop during shutdown. To ensure that these lubrication requirements are met under all conditions, an auxiliary 125 VDC pump remains on standby in the event the main generator-driven pump fails, or turbine shutdown is initiated. The auxiliary pump also supplies lubricating oil to the bearings during startup until the main pump has a chance to reach operating pressure.

The sequencer monitors the lube oil system pressure and generator shaft speed, and activates the auxiliary pump during generator startups, shutdowns, and any other time that the lube oil pressure drops to 12 psig.

System Operation Refer to F&ID Dwg. xxxxxx-751248, Generator Lube Oil System. Lube oil pumps draw oil from the system reservoir through independent suction lines. Both pumps feed a common discharge line. A check valve maintains oil in the generator-driven pump to ensure instantaneous oil flow to the bearing assembly whenever the pump begins operation. Valve PCV-0013 prevents the lube oil pressure in the common discharge line from exceeding 30 psig (207 kPaG) and ports excess oil back to the reservoir. A relief valve PSV-0003 prevents pressure at the output of the auxiliary pump from exceeding 85 psig (586 kPaG).

Heated lube oil from the discharge of either the generator-driven or the auxiliary pump is cooled by a fin-fan heat exchanger, located on the auxiliary trailer, before flowing through the simplex oil filter assembly. The lube oil may bypass the coolers if thermostatic control valve TCV-0000 determines the temperature to be  140 qF (60 °C). As the lube oil temperature increases during generator operation, the valve progressively directs more oil through the heat exchanger until, at 140 °F (60 °C), nearly all the oil flows through the heat exchanger. After the lube oil passes through control valve TCV-0000, temperature indicator TE-0025 measures actual lube oil temperature downstream of the cooler, signaling an indicator and activating an alarm and shutdown. Temperature indicator TI-0025 provides a temperature reading to the electronic-turbine control system. Alarm TAH-0025 activates when temperatures reach 160 qF (71 °C) or higher, and a cool down lock out (CDLO) is activated when temperatures reach 190 qF (88 °C) or higher.

System Operation (Continued) From the heat exchanger, the cooled oil flows into the simplex oil filter. Differential pressure transmitter PDT-0015 indicates the pressure differential across the filter elements. PDT-0015 activates alarm PDAH-0015 at the electronicturbine control system if the differential pressure reaches 20 psid (138 kPaD). Pressure indicator PI-0015 provides a pressure reading to the electronic-turbine control system.

Pressure at the filter output is controlled by pressure control valve PCV-0013 which prevents the supply line pressure from exceeding 30 psig (206.8 kPaG). This valve protects against overpressure, which can force oil past the seals in the generator-bearing assemblies, by porting excess oil back to the reservoir. Pressure transmitter PT-0026 monitors pressure down stream of the filter, signaling an indicator and activating an alarm and shutdowns. Pressure indicator PI0026 provides a pressure reading to the electronic-turbine control system. Alarm PAL-0026 is activated when pressure drops to 25 psig (1170 kPaG) or less. FSLO shutdown PALL-0026 is activated when pressure drops to 12 psig (83 kPaG) or lower. FSLO shutdown PAHH-0026 is also activated when pressure increases to 60 psig (413 kPaG) or higher. From PT-0026, lubricating oil enters the generator shaft-bearing assemblies through the orifice at the non-drive end and another orifice at the drive end. Sensing elements TE-0021 and TE-0023 monitor bearing temperatures, activating an alarm at 197 °F (92 °C) and initiating a shutdown at 203 °F (95 °C). Sensing elements TE-0035 and TE-0036 monitor the temperature of lube oil leaving the bearings, activating an alarm at 189 °F and initiating a shutdown at 194 °F. Sensing elements TE-0021, TE-0023, TE-0035, and TE-0036 transmit this data in the form of 4–20-mA signals to the electronic control system for display on the DCS monitor.

System Operation (Continued) Oil from the bearing assemblies is gravity-drained back to the generator lube oil reservoir. Sight glasses in each drain line permit visual verification of oil flow. The air/oil separator on the lube oil reservoir vents any gases entrained in the returning lube oil. Immersion heater HE0005 maintains the reservoir oil temperature at 90 °F. Tank thermometer TE-0020 monitors reservoir oil temperature, and signals temperature indicator TI-0020, which provides a temperature reading to the electronic-turbine control system.TE0020 also activates alarm TAL-0020 if the oil temperature falls to 70 °F (21 °C). Level transmitter LT-0001 activates alarm LAL-0001 if the oil level drops to 63% of full. LT-0001 activates alarm LAH-0001 if the oil level rises to 87% of full. LT-0001 will initiate a shutdown if the oil level falls to 55% of full.

g 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. Analog Signal: An analog signal is a measurable quantity that is variable throughout a given range and is representative of a physical quantity. Annular: In the form of, or forming, a ring. Anti-Icing: A system for preventing the buildup of ice on the gas turbine intake systems.

APD – Automatic Paralleling Device: Automatically parallels any two gas turbinegenerator sets. B Babbitt: A white alloy of tin, lead, copper, and antimony which is used for lining bearings. BAS – Bleed-Air System: The BAS uses as its source compressed air extracted from the compressor stage of each gas turbine module and gas turbine-generator set. The BAS is used for anti-icing, prairie air, masker air, and low-pressure gas turbine starting for both the gas turbine module and the gas turbine-generator set. Bleed Air: Hot, compressed air bled off the compressor stage of the gas turbine module and gas turbine-generator set. See BAS – Bleed-Air System. Blow-in Doors: The blow-in doors located on the high-hat assembly are designed to open by means of solenoid-operated latch mechanisms if the inlet airflow becomes too restricted for normal engine operation.

g Borescope: A small periscope used to visually inspect internal engine components. BTB – Buss Tie Breaker: A BTB is used to connect one main switchboard to another main switchboard. Buffer: To electronically isolate and filter an electrical signal from its source. Bus: The term used to specify an uninsulated power conductor. C CB – Circuit Breaker: An automatic protective device that, under abnormal conditions, will open a current-carrying circuit. CIT – Compressor Inlet Temperature (T2): CIT is the temperature of the air entering the gas turbine compressor as measured at the front frame. CIT is one of the parameters used for calculating engine power output (torque) and scheduling fuel flow and variable stator vane angle. Coalesce: To grow together, unite, or fuse, as uniting small liquid particles into large droplets. This principle is used to remove water from fuel in the filter/separator. Condensate: The product of reducing steam (gas) to a liquid; (water). For example, as used in the distilling process. D D/A Conversion – Digital-to-Analog Conversion: A con-version that produces an analog output in the form of voltage or current from a digital input. DC – Direct Current: Direct current is an electric current that flows in one direction. A pure direct current is one that will continuously flow at a constant rate. Deaerator: A deaerator is a device that removes air from oil as in the LS&C tank (gas turbine module) which separates air from scavenged oil. Delta P – Differential Pressure: The pressure drop across a fixed device. Demisters: A moisture-removal device that separates water from air. Dessicant: A substance having a great affinity for water and used as a drying agent. Diffuser: A device that reduces the velocity and increases the static pressure of a fluid passing through a system. Digital Signal: A signal, in the form of a series of discrete quantities, that has two distinct levels.

g E Eductor: The eductor is a mixing tube which is used in the gas turbine module exhaust system. It is physically positioned at the top of the stack so that the gas flow from the gas turbine module exhaust nozzles will draw outside air into the exhaust stream as it enters the mixing tube. EG – Electronic Governor: An electronic governor is a system that uses an electronic control unit, in conjunction with an electrohydraulic governor actuator, to control the position of the liquid fuel valve on the gas turbine-generator set and regulate engine speed.

It controls the output voltage of the generator. Governor Droop Mode: Droop mode is normally used only for paralleling with shore power. 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.

g 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.

g Compressor inlet pressure CIP The pressure of the air at the inlet to the inlet guide vanes of the compressor. Normally slightly less than atmospheric pressure.

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. Compressor ratio C/R compressor inlet pressure.
