1. PREAMBLE

It is absolutely essential for the parties participating in the construction and operation of a power plant to agree upon a standard system for the designation and classification of the plant, its part and components.

Due to the size of power plants and the fact that the large number of parties participating are all in different locations, communication problems arise which can incur costs which cannot be estimated in advance. A standard designation system enables each party, irrespective of language and assignment, to identify uniformly and unambiguously, those parts of the plant within its responsibility. The Power Station Designation System KKS satisfies these requirements. The planners and operators of power stations employ a common, standard system for identifying installations, and parts thereof , with which the data required to plan, construct and operate power stations can be collected and processed. This publication reviews the GE Power System application of the Power Station Designation System KKS based on KKS VGB B106e edition dated 2007 & B105e PowerTech GmbH 7th edition dated 2010.

INTRODUCTION OF GE POWER SYSTEM CODING SYSTEM The purpose of this publication is to summarise the structure, contents and application of the KKS. Illustrations of the structure, and the code section of the VGB book without definitions, are used to describe the system. For their internal use, GE Energy have reduced the VGB - KKS code to the specific parts for:  conventional Gas Turbine unit,  thermal plant,  Combined Cycle power plants. The scope of tasks coded in KKS includes the following wherever applicable: Labelling on drawings of:  GT, ST, Generator, and instrument, valves, and equipment in BOP and GE scope of supply using the “process related” coding.  Cubicles, panels, cabinets and junction boxes in BOP and GE scope of supply using the “process related” coding.  Piping.  Interconnect Cables.  Main machinery equipment in DCS HMI’s graphic displays.  BOP DCS signals including group control.  Foundation Field Bus Segment.  Equipment in PLC's displays. The above scope requiring KKS labelling shall be documented on the following “process related” drawings, namely P&Ids / schematics, device summaries, one line diagram, circuit / wiring diagrams of main equipment (GT, ST, Gen, HRSG and their associated modules), Operation and Maintenance manuals narratives, DCS software, site cable diagrams/list. Tagging of equipment:  GT, ST, Generator, and instrument, valves, and equipment in BOP and GE scope of supply using the “process related” coding.  Cubicles, panels, cabinets and junction boxes in BOP and GE scope of supply using the “process related” coding.  Interconnect piping.  Interconnect Cables.  Field mounted wiring & junction boxes for Foundation Field Bus devices. The above scope requiring KKS tagging consist of Name plates / Tagging on physical equipment Tagging of the plant Control and Monitoring system :  Turbines HMI graphics.  DCS graphics.  DCS Input, output and processed signal.  PLC's graphics. The above scope requiring KKS tagging consist of text shown on Graphics close to equipment symbols and text in the DCS toolbox along with signal. The following tasks are excluded of the KKS labelling/tagging:   

Revision D

The systems related to the ST, GT and their generator would be identified using the GE coding system known as “legacy” codes. In addition, a secondary KKS functional code will be given and shown on the P&ID’s (i.e. double identification). Similarly the field devices will also be tagged with KKS coding in addition to the original standard GE tagging. In the DCS all the signals transmitted from the turbine controllers will be given a code according to the KKS identification. A cross-reference list will be provided for all signals exchanged between the turbine controllers and the DCS. This will not be labelled on a GE P&ID. Part ordering system will nominally be based on the GE part number or specific vendor part number for a particular component. For “Package Plants” such as chemical plants, compressors, auxiliary boilers, etc., which are supplied by a vendor in accordance with his standard practice or as catalogue items, the KKS system is not fully applied. However KKS identification is used in case of electrical or I&C interfaces of these package plants with the rest of the plant (i.e. DCS).

REQUIREMENTS TO BE MET BY THE DESIGNATION SYSTEM In order to perform the tasks established, the designation systems must be capable of meeting the following requirements:  Determination of all installations and subsystems  An adequate number of reserve codes must be available for future developments in power plant engineering  Clear identification of all subsystems  A designation used in a power plant must be unique  Subdivision with graded details and a fixed meaning for the data characters  Plausibility check of applied tagging, especially for data processing  Existing standards, guidelines and recommendations must be taken into consideration In order to facilitate the application of KKS for a project managed by a consortium of vendors, GE reserves sections of the sequence numbers for codes used on their GT, ST and Generator drawings. These codes should be reviewed on a project basis to ensure they are consistent with scope and reflect the plant configuration. Exception to reserved codes could be accepted by the parties on a project basis assuring duplication does not occur, and are explicitly outlined during the initial project agreement by all parties.

INTRODUCTION TO KKS 2.1.

DESIGNATION AND TYPE OF DATA CHARACTERS

In consideration of the various requirements placed on the identification of plants, sections of plants and items of equipment in power stations, KKS has three different types of code: Process-related code Process- related identification of systems and items of equipment according to their functions in mechanical, civil, electrical and control and instrumentation engineering. Used by GE Energy for every process. Point of installation code Identification of points of installation of electrical and control and instrumentation equipment in installation units 'e.g. in cabinets, panels, consoles) Mainly used by GE Energy for electrical cubicles and cables. Location code Identification of locations in structures, on floors, in rooms and also of fire areas. Rarely used by GE Energy. May be used for complex installation based on location areas The uniform composition of process related code is used by all engineering disciplines in their planning and engineering tasks, thus ensuring effective integration of information coupled with unambiguous recognition by all concerned. The titles of the breakdown levels of the process related of code will henceforth be as follows: Serial no. of breakdown level

PROCESS-RELATED IDENTIFICATION

In this type of designation the entire system is subdivided according to the function or process. The equipment units and items must be identifiable in relation to the process. The process-related designation is for many applications the most important designation. It permits identification of equipment, instrumentation and signals, by location function and type. In the mechanical, electrical and instrumentation control engineering sectors, the equipment for auxiliary services, power supply, open-loop control, instrumentation, protection, etc., is treated as a process engineering function. This identification has the prefix sign "=". According to the standard, the prefix sign can be omitted provided that the designation remains unambiguous.

It may be necessary to identify units, unit-free plants or expansion stages within a power station, such that a clear and unambiguous distinction exists between them. In such a case, all parties concerned must agree upon this designation with regards to the contents and type of data character (A or N).

The block identifies set of main machinery as gas turbines ,steam turbines or any other type of machine set or production plant and use two characters G F0: G : The block identification: G represent the block within the plant. A block is a set of units that together make a complete production features such as a combined cycle STAG209E (two Gas turbine units, two HRSG and one Steam Turbine unit). F0: The unit or train identification within the block: In power plants, data character F0 shall be a numeric character used for the numbering of the similar systems and plants in the parts of a power station, identified with character G. F0 is part of level 1 but is associated to G in order to clearly identify any unit or sub plant production. G and F0 usage is as follows: The first digit represents the power block, while the second digit is the train, with 0 representing common equipment. For single-shaft blocks 00 11 21 31 41 For multi-shaft blocks 00 10 11 12 13 14 20 21 22 23 24

Common system between blocks (subdivision is possible) Single-shaft block 1 (GT, ST HRSG, & related systems) Single-shaft block 2 Single-shaft block 3 etc. Common system between blocks (subdivision is possible) Steam turbine and its generator for block 1 and common systems for block 1 First gas turbine, its generator, first HRSG and their auxiliaries for block 1 Second gas turbine, its generator, second HRSG and their auxiliaries for block 1 Third gas turbine, its generator, third HRSG and their auxiliaries for block 1 etc. Steam turbine and its generator for block 2 and common systems for block 2 First gas turbine, its generator, first HRSG and their auxiliaries for block 2 Second gas turbine, its generator, second HRSG and their auxiliaries for block 2 Third gas turbine, its generator, third HRSG and their auxiliaries for block 2 etc.

If there are single-shaft units and multi-shaft units in the same site, a combination of the above should be used. The first character G identifies the block (single-shaft, multi-shaft or common systems) and F0 can adopt the values indicated above, depending on the block type (single or multi-shaft). It is not necessary to display Level GF0 on a drawing if it is clearly defined or stated in a note for the project.

GE Energy BREAKDOWN LEVEL 1, FUNCTION PREFIX NUMBER

F1, F2, F3 The alphabetical characters of this breakdown level are used to classify and divide the overall plant into subsystems, systems or building structures. Wherever possible, all three alphabetical characters are permanently allocated, including their associated boundary constraints and task allotment in modern power plant technology. Please refer to Appendix A for a complete list of GE system codes. Subdivision of systems, FN FN numbering allows for a further breakdown and delimitation of a system so that specific sections can be uniquely defined. GE uses a combination of decadal and consecutive numbering based on system complexity. Decadal numbering in subsystem has the advantages over consecutive numbering where subunits (e.g. parallel trains) of piping systems form a subgroup. In each system the main line is divided in decades, and, if not sufficient, with unit numbers within a decade. Other lines (return, bypass, vent, drain, recirculating...) are numbered by unit numbers as subsystems of the relevant decade. Devices on a pipe run will have a matching system coding as the pipe run, except when the primary function of the device is to actuate or influence the action of another device that falls on a pipe run in different system. FN allocation The table in Appendix A presents the most used systems codes F1F2F3 in a combined cycle power plant. Pre-engineered design such as the main product has allocated rigid codes for standardization purposes and are dispatched along with the process need. The site arrangement could defer from project to project and will induce different configuration what may shown a non strict consecutive system ranges. More over the alternation of scope could show alternation of F1 system codes. Refer to the project wise Part C for exact Fn range allocation. Several ranges are devoted to GE product, to the installation engineering and to other equipment scope owners. .

3.3.2.

Coding of process valves and pipes

The alphabetical characters assigned to piping and accessories in the second level are BR. Numbers must be, nominally, assigned in ascending units in the direction of the main flow (increasing in the downstream direction). The pipeline or BR number must only be changed:  When they have different functions from the point of view of process  When there are changes in the process conditions (Pressure, Temperature, Flow)  When there is a change of material  Optionally when there is a change in diameter associating the reducer with the line of greater diameter Changes in diameter caused by reducers for the purpose of inserting valves and instruments will be accepted, as long as the diameter of the inlet pipe is equal to the diameter of the outlet pipe. The number of the line (in the second level) will not be modified when elements considered as integrating parts are installed in the line; for example, valves, temporary filters, expansion joints, restrictive orifices, flow elements, etc. For reserved sequence numbers (AN) for BR units refer to Appendix C. In the field, the interconnect piping is tagged by a coloured ring over marked with the first two letters or the three letters of the KKS system code. a) VALVES The process valves are identified in the first level with the code of its associated pipe (or equipment) and in the second level with the alphabetical characters AA. In the same respect as the sequence numbers (AN) for BR units increase, the different valves will be numbered correlatively. An attempt will be made to adopt numbering that ascends in the direction of the main flow. Appendix C reserves blocks of numbers (AN) specific to valve function in order to provide information concerning the type of valve that is being denominated. With the exception of pilot valves shown on P&IDs, which use the main valve code plus the breakdown level A3, set to A, B, C, etc. in order of need. Refer to Appendix F, example number 5. b) BYPASSES In order of importance, denomination of a bypass is determined as follows:  Consecutively within the corresponding decade in accordance with the numbering established in the first level for the system to which they pertain (system bypasses).  Consecutively within the corresponding unit numbering of sections in accordance with the numbering established in the first level for the system to which they pertain (sub system or main equipment bypasses).  Fully integrated as part of the system to which they pertain (equipment bypasses or valve bypasses). c)

DRAINS AND VENTS

Drains and vents are denominated in the first level as a bypass of the system to which they are designed to drain or vent. Such denomination covers up to the last closing device or the discharge pipe to the atmosphere. d) HEAT EXCHANGERS

Because of their function, heat exchangers form part of at least two systems. However, because of the need to establish single identifications, they must be assigned to just one of the systems. Heat exchangers are assigned to the system that requires its services; the system that absorbs heat in the case of heaters and the system that gives out heat in the case of coolers. e) IDENTIFICATION OF PIPING SYSTEMS The following specifications are valid for identification and representation in P&IDs: Numbering in the first breakdown level is effected for parallel piping legs in increasing increments, counting in the flow direction. A hollow needle represents delimitation of the system identification in the first breakdown level (F1F2F3FN).

For better recognition of the coding delimitation, the needle is not placed directly in the branching or junction point, but in the line concerned. A solid needle represents delimitation of the piping identification or BR number in the second breakdown level (AN).

Identification of the piping systems is carried out using "flags". The direction of the "flag" is to indicate the flow direction. The flag shall contain the 1st Breakdown level. The unit code BR.. is written below the flag as follows: LBA10 BR010

LBA20 BR010

If two flow directions are possible, lines are placed on both ends of the box. LBA30 BR010

An oblong bubble typically represents the measuring points in a plant. These bubbles have 2 lines of coding inside them. On line 1 is the measurement type and the associated function(s) in the plant. On line 2 is the KKS tag of the instrument. The legacy code or standard code used by suppliers, is mentioned either in a third line or beside the bubble. Line 1: Function letter of the measuring point according to paragraph 3.3.4 a Line 2: KKS level 2 – identification mark of the measuring point

a) MEASUREMENT TYPE & FUNCTION (LINE 1) To describe the measured variable and function, each measuring symbol is provided in line 1 with a number of identification letters. These identification letters are determined according to ISA S5.1. The first set of letters, identifies the measured variable. The second set of letters indicates the signal processing of the measured variable. The ISA table below is used as appropriate for instrumentation use only.

APPENDIX F: EXAMPLES IN USE AND CASE STUDY 1° Redundant instrument:

Redundant instrument measuring the same processing value are segregated by the A3 code MBP70 CP003A redundant remote pressure measurement MBP70 CP003B redundant remote pressure measurement MBP70 CP003C redundant remote pressure measurement 2° Measurement of identical process value used in different control loops:

Multiple instrument at the same point of installation measuring values used for different control loops or controllers, they are differentiated by the AN code. MBP70 CG311 limit switch closed MBP70 CG312 limit switch open

3° Multiple measuring circuits housed in the same body This pertains to thermocouple having several sensors housed in the same body in order to get a back up instrumentation in case of failure of the main. This is avoiding dismantling the thermocouple by stopping the system. Each sensor is a component of the thermocouple and is tagged as follow on circuit diagrams: MBP70 CT001–B01 MBP70 CT001–B02 MBP70 CT001–B03 In the P&ID’s this thermocouple is shown as a unique control point as MBP70 CT001. 4° Equipment or Piping mounted in parallel: The example codes below show the different methods for changing coding for items in parallel on a P&ID. Example for Piping Line, 3 pipes in parallel depending on the importance of the lines it will change the Level 1 (decade or unit) or the level 2: MBA10 BR001 MBA20 BR001 MBA30 BR001
