0. PREFACE

The main purpose of this handbook is to define the methods used by Landsnet for identification in mechanical-, civil-, electrical-, control and instrumentation engineering.

For this purpose Landsnet has chosen the identification system KKS (G: Kraftwerk Kennzeichnen System, E: Identification Systems for Power Plants). Landsnet has certain guidelines which are within the limits given by VGB (Technische Vereinigung der Grosskraftwerksbetreiber E.V.). These guidelines apply on the different Break Down Levels (BDL) in the identification system. This KKS-handbook contains certain guidelines made by Landsnet. The KKS codes shown in this handbook are only for clarification and can not be used directly during any project. The guidelines do not replace the guidelines from VGB, listed in Chapter 1. The compendium of Directives from the Owner to the Contractor regarding the use of KKS for Landsnet on the following pages, has to be studied carefully prior to any work carried out in connection with KKS coding. The KKS Guidelines do not contain all the rules necessary for a Project. There are gaps for which clear definitions shall be made between the Owner and the Contractor described in this Compendium, prior to the start of identification with the aid of KKS. In the Guidelines such aspects are indicated by the remark Details of application are subject to agreement between the parties to the project. A list of such agreements is given below. The KKS Guidelines are listed on pages P.3 and P.4 and all KKS-Application Commentaries form an integral part of the Guidelines. If there are any disputes between the Guidelines and the Handbook, the Handbook shall prevail. In this KKS Handbook there are special rules which apply for Landsnet and are not described in the Guidelines, and a list is given here below.

1.1 SCOPE OF KKS

The Identification System for Power Plants KKS serves to identify Power Plants, sections of plants and items of equipment in any kind of Power Plants according to task, type and location. It also serves to identify Sub Stations and overhead lines in the same manner. The KKS key is based on the IEC and ISO standards together with the DIN 40719 PART 2 (IEC 750). These KKS guidelines do not contain rules on:

Combination of the code with other identification systems.

Methods of marking, e.g. in control rooms, local control stations, labelling off components and identification of documents.

Open text abbreviations.

Identification/numbering of drawings. The following guidelines and explanations issued by VGB are valid, and where not in contradiction to the handbook, they do apply.

1.1.1 TYPE OF CODE

The KKS has three different types of codes, which can be used together or separately. These codes are the process-related code, the point of installation code and the location code. These codes are subdivided into 3 and 4 Break Down Levels (BDL).



KKS

December 2008





Process related Code

Process related identification of systems and items of equipment according to their function in mechanical, civil, electrical and control and instrumentation engineering. As example there are pipes, pumps, valves, motors, measurements, switches, transformers etc.

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 etc.

Location Code

Identification of various structures, such as dams, tunnels, buildings, floors, and rooms and fire areas. This code is also used in connection with preventive maintenance of buildings and structures. Further more this code is used to identify the location of mechanical components in the same manner as the point of installation code is used in electrical- and control and instrumentation engineering.

1.1.2 BREAK DOWN LEVELS, PREFIX AND BREAKDOWN SYMBOLS

Definitions for prefixes and breakdown symbols for writing these codes are in DIN 40719, part 2. The following fig. 1.1 shows the role of the codes on different BDLs.

Fig. 1.1 Break Down Levels for various types of codes

The full stop breakdown symbol for point of installation identification must always be written. The prefix symbols may be omitted if the information content of the codes remains unambiguous.

In front of these codes there is a BDL 1 and this BDL is used for identification of Power Plants and Sub Stations. It does not belong to the KKS code issued by VGB, but has been decided upon by Landsnet, (see table 1.1 - 1.4). As an example the following is mentioned:

BDL Area Example KKS 1 Sub Station Teigarhorn S.S. TEH 0 Part of a S.S. Line 132 kV to HOL HO1 1 System Line bay 132 kV 1AEL10 2 Equipment (part of system) Circuit breaker GS100 3 Component (part of equipment) A fuse -F01

1.1.3 KKS CODE

The KKS code consists of alpha letters (A) and numbers (N). The code is divided in 4 (0-3) BDLs in the process related code and in 3 (0-2) BDLs in the point of installation code and the location code. BDL 0 1 2 3

1.2 CONTENTS OF DATA CHARACTERS

It shall be clearly stated that all explanations in this book are related to the process code unless otherwise specified. In the KKS key the use of the alpha symbols (A) is defined in most cases. Still there are some codes that are available for free use, see chapters 4.10. The definition of the use of numerical symbols (N) is defined in this book, according to the regulations valid by Landsnet. The letters I and O are not permitted on BDL 1, 2 and 3 in the KKS code, to avoid misunderstanding between I and 1 (one) on one hand and O and 0 (zero) on the other hand. The Icelandic alphabetic characters , , , , , , , , and are not permitted and only capital letters are allowed.

Table 1.3 BDL 1

The BDL 1 is used for definition of names of areas or constructions, which are to be coded. This BDL is free for use, so the short names of the Power Plants and Sub Stations are used for identification. If more than one Power Plant is using the same water impounding works, they have the same name on this BDL.

Normally alpha symbols are used on BDL 1 and they occupy 3 places.

Table 1.6 BDL 0.

The KKS key allows the use of alpha- and numerical symbols on BDL 0. In case of one Power Plant with its own water impounding works, BDL 0 is defined as zero and written 000. When more than one Power Plant shares the same water impounding works (W.I.W), the W.I.W. get a 000 (zero) on BDL 0 and each station is numbered, so that the oldest one gets the number 001 the next one 002 etc. Common equipment for two or more stations will always receive the number 000. Example:

On this BDL (F1, F2, F3) the original KKS key applies. Some keys (F2, F3) in this group are given free for use so that they can be used as it suits the purpose of coding. This also applies to some keys on BDL 2 (A2) and on BDL 3 (B2). Some keys (F3) in the group of ancillary systems are given free for use to separate systems in various buildings. The use of these characters has been defined by Landsnet, and this is shown in chapter 3. and chapter 4. It is not permitted to use keys that are blocked in the code. They cannot be used under any circumstances. These keys are blocked for future use. The FN numbers are used for coding within the same system. As an example the main code for a generator rotor is MKA 20 and for a generator stator the main code is MKA 40.

In the KKS key equipment is coded/defined by A1, A2 e.g. valves, pumps, switches etc.. The AN number is a consecutive number which is used to number identical equipment, which is identified by A1, A2, within the same system. It has been decided by Landsnet how these numbers shall be used in case of parallel- and serial connected systems in the mechanical engineering and also in the electrical part, where 3 phase systems are coded and A3 is used to separate e.g. cores in measurement transformers see chapter 4. When A3 is not used, it is not written in the code.

2 NUMBERING

The KKS code allows a certain possibility of free/individual use of numbering code elements. This chapter shows the rules for using the FN and the AN numbers. The rules defined here are binding for the KKS coding for Landsnet. In some cases it is possible to use some other way of numbering, in those cases the Landsnets KKS committee will set the standard for that numbering. The source for this are the KKS Guidelines from VGB, together with Part A and Part B (booklets B1, B2, B3 and B4) also from VGB. 1. Numbering starts again when one of the preceding code elements changes. 2. Numbering may be done in units or decades. It depends on the system thats

being used. 3. Numbering is as a rule in the direction of flow. 4. Numbering shall be from left to right or from top to bottom. It is permitted to use

numbering that exists in old Power Plants though it isnt in the right direction. 5. It is preferred to use gaps in the numbering, to simplify later changes. The numbering with FN and AN shall always be in the direction of a flow as often as possible. If however the flow has two directions, one direction shall be defined as NORMAL OPERATION. The flag symbol represents codes for pipes. A flag with one leg points in the direction of flow while a flag with two legs indicates that the flow can be in both directions, depending on the mode of operation.

Fig. 2.3 Decades numbering, variant 2.

Numbering in decades is convenient for large systems. Each case shall be treated uniquely depending to how the system is built when decades numbering is used. Decades numbering shall be used in main and extensive systems, but sub-systems shall be numbered using units. Consecutive numbering shall only be used within the same system or within the same part of a system where components are in parallel connection.

2.1 FN NUMBERING

FN numbering is used to divide systems in parts or subsystems. FN is done in decades (10,20,30....etc.) or consecutive (11,12,13,14......etc) FN numbering should be minimised. If no further FN numbering is needed then the decade 10 should be used in the FN seat. Numbering with FN in large plumbing systems should be clearly divided, e.g. by areas, by levels, by machinery and by large parts of machinery with decade numbering but with consecutive numbering in parallel connected system. Example of FN numbering is found in chapter 3, Identification in mechanical engineering. Upper and lower guide valves are numbered in decades (10,20,30 ...) but individual parts of the guide valves are numbered consecutively (11,12,13 ...).

2.2 AN NUMBERING

AN numbering is used to divide systems in single parts. AN numbering shall be in decades (_10, _20, _30 .) or in consecutive (_11, _12, _13 ..). For numbering of electrical and pipe line systems separations shall be clear. E.g. use decade numbering for separation along main branches and use consecutive numbering for separation along parallel connected branches.

2.2.1 NUMBERING OF PIPING SYSTEMS

Normally, pipes are not coded, but where needed e.g. in Thermal Power Plants, the following rules shall be used: Decades numbering shall be used for the identification of main piping systems, 010, 020, 030...., e.g. when the role/function changes, e.g. when pressure, temperature etc. change. Consecutive numbering shall be used for sub-piping systems e.g. bypass, pipes for control valves etc. which receive the numbering 011, 012, 013..... or 021, 022, 023.... etc.. Consecutive numbering is also used for pipes for control circuits, air- and water drainage, instrument lines, sampling lines and safety lines. These are numbered with _01, _02, _03,...etc.. Attempt should be made to distinguish the pipes in a sub piping system from the pipes in the main piping system, e.g. first pipe in sampling line from main pipe 010, 020, 030 shall be numbered 411, 421, 431 etc. The numbering of the following pipes shall be grouped by counting in hundreds in the following way: 0 _ 0 for main piping system 0 _ _ for sub piping system 1 _ _ for control circuit piping 2 _ _ for drains and vents 3 _ _ for instrument lines (if numbered) 4 _ _ for sampling pipe lines 5 _ _ for safety line piping.

2.2.2 NUMBERING OF VALVES

Decades numbering shall be used for valves in a main piping system, 010, 020, 030, etc. when their role/function changes, e.g. when pressure, temperature etc. change. In sub-piping systems, valves like bypass valves, control valves etc. shall be numbered 011, 012, 013.... or 021, 022, 023... etc. Consecutive numbering is also used for valves for control circuits, air- and water drainage, instrument valves, sampling valves and safety valves. They are numbered with _01, _02, _11,_12,...etc. It is preferred to number valves from valve in main plumbing system, e.g. the first valve in sampling system from a valve in the main plumbing system 010, 020, 030, should be numbered 411, 421, 431 etc. The numbering of the following valves shall be grouped by counting in hundreds in the following way: 0 _ 0 for valves in main piping system 0 _ _ for valves in sup piping system 1 _ _ for control valves 2 _ _ for valves in drains and vents 3 _ _ for isolation valves in instrument lines 4 _ _ for valves in sampling lines 5 _ _ for valves in security lines

Table 3.9 Coding of air-condition systems on BDL 1.

3.5 CODING OF GEOTHERMAL POWER PLANTS

Coding of Geothermal Power Plants is as shown in table 3.10. The main parts of the plant is grouped on BDL-1 where the numbering of the items is done.


L B A - - Steam production from well to and with out steam Separator L B B - - Steam supply from Separator to and without turbine main stop valve L B J - - Steam and moisture Seperators

Table 3.10 Coding of Geothermal Power Plants on BDL 1.

This is slightly different from the KKS key. This is necessary because the KKS key is designed for regular Thermal Power Plants but not Geothermal Power Plants. These definitions should only be used in Geothermal Power Plants. If coding a regular Steam Power Plant then the KKS key shall be used as it is from VGB.

4.2 CODING OF BUSBARS

Busbars are coded according to the process code. They are coded with 0 on F0 on BDL 1 and under A or B on F1 on BDL 1. In group A, busbars that are connected to transmission lines and line bays which are outgoing lines from Power Plants and Sub Stations. Electrical distribution in group B, is distribution needed for the production, transmission and distribution of electrical energy. On F2 they shall be coded according to the voltage levels, defined in the KKS key, see table 4.2. On F3 they shall be coded A for A-busbar, B for B busbar or V for spare busbar. Numbering is on FN.

Circuit breakers disconnectors and earthing switches are coded as shown in table 4.9, they are separated on BDL 2 where numbering is made. Breakers are named GS_ _ _ and are counted in hundreds with the AN numbers in such a way that the circuit brakers are in the group 100, disconnectors are in group 200 and earthing switches are in group 300.


G S 1 0 0 - Circuit breakers G S 2 0 0 - Disconnector on busbar G S 2 1 0 - Disconnector on A busbar G S 2 2 0 - Disconnector on line and transformer G S 2 3 0 - Disconnector, bypass disconnector G S 2 4 0 - Disconnector, direct connecting of lines G S 2 5 0 - Disconnector on a spair busbar G S 2 7 0 - Disconnector on B busbar G S 2 9 0 - Disconnector on connection of A and B busbars G S 3 0 0 - Earthing switch on line, transformer and busbar G S 3 1 0 - Earthing switches on circuit braker G S 3 2 0 - Earthing switches on circuit braker G S 3 3 0 - Earthing switches on line, transformer

Table 4.9 Coding breakers on BDL 2.

For further information see fig. 4.3 to 4.9. In special cases table 4.11 does not apply, those cases are in table 4.10. Two special cases are in Hamranes og Hrauneyjafossst. In Hamranes on the 11kV there are two circuit breaker carriers for each circuit breaker, circuit breaker carrier one shall be coded GS100 but circuit breaker carrier two shall be coded GS105, see picture 4.10. In Hrauneyjafossst the line disconnector is coded GS200 because of special circumstances, see picture 4.11.

4.4 CODING OF MAIN- AND DISTRIBUTION TRANSFORMERS INCLUDING EQUIPMENT CONNECTED TO TRANSFORMER

In F0 on BDL 1 the equipment gets the same numbering as in F0 for the transformer. When there are several transformers counting is done here. Circuit breakers and disconnectors as well as all equipment connected to transformers which are connected to busbars shall be coded in F1 on BDL 1 according to the busbars to which it is connected. F2 has a figure according to the voltage level on the equipment in question (see table 4.2). The transformer is coded by his highest voltage. F3 is T indicating transformer and transformer equipment. If the transformer is connected to a busbar for distribution inside a Power Plant, the equipment connected to that busbar is coded with the busbar but not with the transformer.

4.5 MEASURING CIRCUITS

4.5.1 CODING OF CURRENT- AND VOLTAGE CIRCUITS

Electrical measurements are coded as shown in table 4.11. The main parts are named CE_ _ _ and are numbered by hundreds on AN.


C E 1 0 0 - Current C E 1 0 1 - Current phase L1 or R C E 1 0 2 - Current phase L2 or S C E 1 0 3 - Current phase L3 or T C E 2 0 0 - Voltage C E 2 0 1 - Voltage phase L1 or R C E 2 0 2 - Voltage phase L2 or S C E 2 0 3 - Voltage phase L3 or T C E 3 - - - Measurement with different variables, (i.g. power, energy, inductance

and resistance, cos) C E 4 - - - Not in use C E 5 - - - Frequency C E 6 - - - Special measurements (i.g. earth fault measurements). C E 7 - - - Not in use C E 8 - - - Not in use C E 9 - - - Common/mixed measurements.

Table 4.11 Coding of current- and voltage measurements, BDL 2.

Normally, current transformers and voltage transformers are only coded down to BDL 2. Mcbs, switches, visual measurements etc. are coded on BDL 3, if needed. Measuring transformers are coded in the same manner as the part to which they belong. Current measuring transformers connected to generator busbars are for example coded BAA10 CE100 but current and voltage transformers connected to low voltage main distribution and auxiliary distribution systems are coded BFA10 CE100 and CE200. If, there is more than one measurement (cores) from the same transformer, the letters A, B etc. are used in seat A3, i.g. CE100A, CE100B (see fig. 4.31). In a multi-line diagram of measuring circuits numbering is done with AN numbers. Consecutive numbering is used. Phases in current measurements are for instance separated on BDL 2 by numbering, 101, 102 and 103.
