Since the latest publication of the KKS Guidelines and the key part in the year 2007 the VGB-Working Panel “Reference Designation and Plant Documentation” dealt various applications for amendments respectively specification of the KKS keys. The demand for the applications resulted from new technologies for power plant process, especially for technologies for CO 2-separation und the use of renewable energy sources. In addition the results of experiences in the project management were integrated. Decision was made to implement the results as index “E”. Please see thereto the revision sheet 7, status January 2010.

Preface Preface to t he Guidelines, 6th Edition 2007

Since the latest publication of the KKS Guidelines and the key part in 2003 the VGBWorking Panel “Reference Designation and Plant Documentation” dealt various applications for amendments respectively specification of the KKS keys. Decision was made to implement the results as index “d”. As addition the existing Application Explanations Explanations have been amended amended by the part „KKS Application Explanations for Hydro Hydro Power Plants (VGB-B 106 D1e)“. This edition corresponds to the german edition 06/2007, index “d”. VGB thanks to the companies involved and the staff members assigned by these with the work. Suggestions and comments to the guidelines and the keys would be appreciated by the VGB- office. Essen, August 2007

Preface to t he Guidelines, 5th Edition 2003

With the 5th edition 2003 the layout was adapted on the form used by “VGB PowerTech Service GmbH” since the year 2000 and the text of the Guideline B 105 was converted to standardized electronic formats. The VGB Technical Committee “Technical Classification Systems” often specified in the KKS Guidelines, became to the Working Panel “Reference Designation and Plant Documentation” due to the structural changes of VGB in the last years. This Working Panel treated various applications for amendments respectively specifications of the KKS function and equipment unit keys since the publication of the last revision 1995. The met resolutions are mentioned in index “c”, as at October 2003. By thus the German and English editions of the KKS set of rules have the same contents and edition conditions. As addition the existing Application Explanations have been amended by the part „KKS Application Explanations for Hydro Power Plants (VGB-B 106 D1)“. VGB thanks to the companies involved and the co-workers assigned by these the work. Suggestions and/or references to the Guidelines and keys receive the VGB-office gladly. Essen, in January 2004

Purpose and Fields of Appl ication

1.1

Scope of KKS

The Identification System for Power Stations "KKS" serves to identify plants, sections of plants and items of equipment in any type of power station according to task, type and location. It is to be used by all engineering disciplines for planning, licensing, construction, operation and maintenance. The KKS, or sections thereof, can be combined with other identification systems in order to meet additional identification requirements. One particular combination is that with the redundancy code. Redundancy codes result from the need to identify redundancy groups. Redundancy groups are defined in KTA 3501 as combinations of items of equipment in a particular arrangement intended to ensure the independence of redundant items of equipment. The items of equipment within a given redundancy group are identified in keeping with the format for the total plant in accordance with the KKS Guidelines. Referencing of redundancy groups is performed outside the scope of the KKS code with the aid of a separate redundancy code. This is not covered by these guidelines. 1.2

Requir ements on KKS

The following requirements are considered: -

Uniform identification for all types of power station and any connected processes

-

Sufficient capacity and detail for identification of all systems, components and structures

-

Sufficient capacity for extension to accommodate new technologies

-

Consistent identification for planning, licensing, construction, operation, maintenance and waste management

-

Interdisciplinary applicability to mechanical engineering, civil engineering, electrical engineering and control and instrumentation combined with ability to identify according to process functions, points of installation and locations

-

Consideration of national and international standards

-

Non-language-based coding to ensure international usability

-

Application in computer processing

1.3

Featur es of KKS

To fulfil the above-mentioned requirements, KKS has the following features: -

Hierarchically structured format with 4 breakdown levels and fixed alphanumeric data characters

-

Separate identification methods with engineering discipline-specific rules by means of a uniform code format for the three types of identification

9

- Process-related identification - Point of installation identification - Location identification In relation to the identification of plants, systems and items of equipment KKS considers the following standards: Content

-

Combination of the code with other identification systems

-

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

-

Open text abbreviations

-

Format of Code

2.1

Types of Code and Breakdown Levels

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 -

Point of ins tallation code

Identification of points of installation of electrical and control and instrumentation devices in installation units (e.g. in cabinets, panels, consoles) -

Location code

Identification of locations in structures, on floors and in rooms and also of fire areas and topographical stipulations (surface area grid) These three types of code use the same identification scheme, which is subdivided into max. four breakdown levels. The titles of the breakdown levels of the three types of code will be as follows: Serial no. of breakdown level

The "full stop" breakdown symbol for point of installation identification must always be written. The prefix symbols may be omitted if the information contents of the codes remain unambiguous. 2.3

Format of Breakdown Levels

The code consists of breakdown levels. The individual breakdown levels are differently formatted. They consist of classifying and numbering code elements. The latter consist of data characters occupied by alpha characters and numeric symbols. Serial no. of breakdown level

A = Alpha characters (Roman letters except I and O, and special symbols) N = Numerical characters (Arabic numerals)

Within the breakdown levels and within the code groups the data characters places from the left to the right smaller becoming units. Read from left to right no data characters may be omitted. Special guidelines apply to data characters G, F0 and A3.

Maingroups F1 Groups F2 Subgroups F 3 Maingroups A1 Subgroups A 2 Maingroups B1 Subgroups B 2 The classifying coding letters and designations are project-independently in the KKS keys as follows: -

Function key, for F1 / F1 F2 / F1 F2 F3 on breakdown level 1

-

Equipment unit key, for A1 / A1 A2 on breakdown level 2

-

Component key, for B1 / B1 B2 on breakdown level 3

The plain text designation of the key may be modified on a project-specific basis but only provided that no content changes take place. Modifications must be taken by the parties involved to the project. "Blocked" coding letters are reserved for future technologies and new engineering systems. They may only be allocated and released by the VGB Working Panel Reference and Designation of Power Plants. The letters of the alphabet are divided up between the main groups A 1 and B1 . For this reason certain letters may not be used within each group.

These numbering code elements are subject to agreement between the project parties and are project-independently regarding the numbering systems and the direction of numbering. However, the following principles apply: -

As a rule numbering starts anew when one of the preceding code elements changes.

-

Numbering may be consecutive or grouping.

-

Numbering need not be continuous.

-

Numbering conventions, once established, may not be altered, not even in the event of changes made in the progress of planning.

-

Redundant zeros must be written. Exceptions are fixed in the following one.

-

An application-specific scheme of numbering may be established. However, such schemes may not have the effect of reserving numbers in other applications, not even within the same engineering discipline.

For the direction of numbering (or lettering) project-dependent local characteristics are determining. The definition of numbering direction in the breakdown level 0 should take place together with the numbering direction in the prefix of breakdown level 1 (see also there). Breakdown level 0 may be omitted if the remaining characteristic remains clear. This has to be specified between the project parties.

Notation of Codes

The codes can be written with and without spacing but however it must be represented in such a way that misinterpretations are avoided. The allowable way of writings is fixed. Their use for any intended purpose is to be specified between the project parties. Spaced way of writing supports the detectability and memory quality of codes. It can be spaced by blank codes as well as by more-cellular way of writing "Small spacing" Blank spaces or dividing lines between the breakdown levels for codes which do not have visually to be seized within a time limit. "Large spacing" Blank spaces or dividing lines between the alpha part and the numeric parts within the breakdown levels, if these are more than four data code places long, e.g. for codes in the control room, where in relatively short time codes must be seized.

Special Rules

5.1

Rules to the Keys

The KKS Key is divided into the following key parts: -

Function Key

-

Equipment Unit Key

-

Component Key

Free spaces:

A number of coding letters in main groups F1 groups F2 and subgroups F 3 have been reserved, for example to allow inclusion of future technologies. In main groups A 1 and B1, as well as in some subgroups, some coding letters have also been reserved. All reserved coding letters can only be allocated with the agreement of the VGB Working Panel “Reference Designation and Plant Documentation”. In the Function Key it is not possible to make generally valid rules for certain coding letters in data characters F 2 and F3 since they depend exclusively on the configurations and arrangements concerned. Similar considerations apply to A 1 = E and G in the Equipment Unit Key. In such cases a remark with the following meaning appears in the key part concerned: " ...free for u se for"

i.e. the letters thus annotated may be used within the terms of the stated definitions

or " ...free for use"

i.e. unreserved letters may be used without any restrictions within the terms of the stated definitions in F 1 resp. F2

Details of application are to be specified between the project parties.

31 Interfaces

The relevant pages of the Function Key show the interface definitions with the meanings given below:

"from incl."

means "including" the named item

"from excl." means "excluding" the named item "to excl."

means "excluding" the named item

"to incl."

means "including" the named item

For some main groups F 1 as e. g.: F

Handling of nuclear equipment

J

Nuclear heat generation

K

Reactor auxiliary system

the task of the system concerned is defined in addition to or instead of the interfaces. 5.2

System Codes for Heavy Machi nery

Certain 'components' such as steam turbines used as drives for feedwater pumps can require so many identification details that, as 'heavy machinery', they need separate system codes in order to permit identification of all associated mechanical equipment units and electrical, control and instrumentation facilities. The system codes for such heavy machinery are fixed as X in main group F 1 . 5.3

Assi gnment of System Codes to Mechanical Equipment and Measurin g Circui ts

Equipment units are allocated to the system in which they are installed. When stipulating system boundaries the originator principle applies. For identification purposes, measuring circuits are allocated to the system where the parameters are measured. 5.4

Special Rules for Mechanical Engineering

5.4.1 Valves Valves as control elements in medium-prominent systems are allocated to the system in which they are installed. Irrespective of their type of actuation they are identified by AA in breakdown level 2. Valves in medium-prominent measuring circuits are allocated to the measuring circuit and are identified by KA in breakdown level 3.

32

Shutoff valves between medium-prominent systems and a measuring circuit are allocated to the medium-prominent system and identified by AA in breakdown level 2. Note: the originator principle does not apply here. Safety equipment comprising safety valves and the connected piping is allocated to the system to which it is connected. Note: the originator principle does not apply here. 5.4.2 Supports Supports are not identified in line with the originator principle. They can be allocated to a system designation or a building/structure designation in breakdown level 1. System-oriented identification is a feasible alternative when parts of the support can be allocated to a particular system. A building/structure-oriented identification is preferable when parts of different systems share supports. Supports are identified by BQ in breakdown level 2. Details of application are to be specified between the project parties 5.4.3 Supply Systems Where equipment units identified in breakdown level 1 and 2, require their own supply systems, these supply systems are identified as subsystems to the overall system with an identification code in breakdown level 1. Supply systems serving several main groups of breakdown level 1 are treated as independent supply systems and are provided with a key within the following main groups in F1: G

Water supply and disposal

K

Reactor auxiliary system

Q

Auxiliary system

S

Ancillary system User (system)

Special Rules for Civil Engineering

If a building or structure covers several engineering process systems, the code for this building is priority-specified. Details of application are to be specified between the project parties. For the identification of special structures, ducting and bridge structures in main group F 1 = U the subgroups F 3 = X

Special structures

Y

Bridge structures

Ducting structures

are stipulated in almost all cases. 5.6

Special Rules for Electri cal, Contro l and Instru mentation Engin eerin g

5.6.1 Shared Equipment for Electrical, Control and Instrumentation Engineering Combined electrical, control and instrum entation equipment

Combined electrical, control and instrumentation equipment for measurement, closed- and open-loop control and power unit (e. g. combined in one cabinet) are identified in breakdown level 1 using the letters CM to CT (subdivision for system combinations). If necessary a further grouping can be made in F N. Transducer Racks, Supports, Scaffolding

These are not identified according to the originator principle. They can be allocated a system code (e. g. auxiliary equipment at main machine sets and heavy machinery) or a building/structure code in breakdown level 1. In breakdown level 2 transducer racks, supports and scaffolding must receive the key GZ. Subdistributo r, Penetrations

These are not identified according to the originator principle. In breakdown level 1 they are provided with the code for the building/structure and floor in which they are located.

34 Exceptions are, for example, the subdistributors at the main machine sets and heavy machinery and the subdistributors in electrical, control and instrumentation cubicles and cabinets, which in breakdown level 1 are identified according to the main machine set or heavy machinery, cubicle or cabinet. In breakdown level 2 the subdistributors are to be identified by the key A 1 = G (electrotechnical equipment). Penetrations through the reactor containment

Such penetrations are identified by JML=reactor containment, cable penetration in breakdown level 1 according to the originator principle. Connections

Identification of connections is performed in line with DIN 40719 Part 2 in a dedicated code block separated from the existing code designation by a colon ":" as required and according to the originator principle. This code block may contain any combination of alphanumeric symbols. Cable Number

For the classifying part of the cable characteristic the characteristic one of the two cable goals is used totally or partly, whereby the characteristic of the cable goal is usually used, which stands further in front in the alphabet. The numbering part of the cable no. consists of four numerical data characters or of three numerical and one alphabetical character; grouping according to voltage level, for example, is allowable. 5.6.2 Electrical Equipment Transform er Systems for Power Transmission and Auxili ary Power Supply

These transformers are identified on breakdown level 1. In breakdown level 2, the individual windings are identified (but not on a phase-specific basis) by means of GT for transformer equipment and numbered starting on the high-voltage side. For further details see DIN 42513. Switch gear, Battery Chargers, Inverters and B attery Sets

These systems and items of equipment are identified regardless of equipment location in the classifying part of breakdown level 1 in accordance with the rules for main group F1 = B. If the letters available are insufficient, FN may be used. In such instances the first character of FN has a classifying purpose. In the second number of F N the fields are counted over. 5.6.3 Control and Instrumentation Equipment 5.6.3.1 Measuring Circuits The identification code of the measuring circle covers the recording of measurement, preparation and distribution as well as the registering and indicating measured variable processing. Measuring circles are assigned marking-technically to the system, in which the measured variable is measured. On breakdown level 2, direct measuring circuits are identified by means of A 1 = C, indirect measuring circuits (linked or calculated) by means of A 1 = F and in A2 according to the measured physical variable (e.g. pressure, temperature) in accordance with DIN 19227 Part 1.

35 Equipment Unit-Specific Analog Signal Processing and Measuring Circuits

Equipment unit-specific analog signal processing elements comprise control and instrumentation equipment which is only provided for one equipment unit such as control interface, protective logics, instruments in the feeder and command termination for final control elements. These analog signal processing elements receive the code of the equipment unit concerned. System-Specific Analog Signal Processing

System-specific analog signal processing elements comprise links between more than one measuring circuit and/or equipment unit-specific analog signal processing elements for systems such as open-loop controls (but not control interfaces). They encompass the control and instrumentation equipment for more than one equipment unit and are identified on breakdown level 2 by means of A 1 = E (analog and binary signal conditioning). A 2 identifies control and instrumentation functions (e.g. alarm links, subgroup control). System-Interfacing Analog Signal Processing

Where control and instrumentation equipment serves more than one process system identified in F2 and F3 , the letter Y for generic control and protection systems may be used in the appropriate data character on breakdown level 1. Control and instrumentation equipment which serves more than one main group may be identified under main group C for control and instrumentation, e.g. unit control system = CJA.

Main machine set

Given the possibilities shown in the table, it is not practicable to meet all possible requirements for identification of discrete process-related functions (e.g. functional group control). Thus for example, it may be necessary to use items which are identified differently on breakdown level 1 (main system and associated parts of auxiliary and ancillary systems) in order to fulfil a given process-related task (functional group). Identification of the functional groups involved in process-related tasks so as to relate them to the principal task concerned may be performed by using the alpha characters in F 1 F2 F3 of the principal process-related task. In this application, however, a suitable identifier such as a prefixed Y should be used to indicate that a software coding unit is concerned, thus to rule out confusion with processrelated codes. This code has to be specified between the parties to the project.

36 An alo g Si gn al Li nk age

In principle it applies with signal logics that after linkage for e.g. reporting linkages the characteristic of the signal which can be processed remain keeping as far as possible. Linked analog signals representing physically similar direct measured variables are identified by means of a set number, e.g. "9", in the first data character of AN and retain the code of the physical variable in data character A 2 . Linked analog signals representing physically dissimilar indirect measured variables are identified by means of A 2 = U (combined variables). Where signals or measured data are used to limit or suppress the original measured data, the processed output signal retains the code of the original measured data. Where measured data are corrected (e.g. flow measurement corrected for pressure and temperature) and if only the corrected measured data are further processed, the codes stay the same as those of the original measured data in spite of the gating of dissimilar measured data. If calculated measured values from linkages of measured value from the origin measured value are to be differentiated to, then the indirect (calculated) measured variable is to be marked by A 1 = F (indirect measuring circles) in the data code place A1. The identification in the data code place A 2 takes place after physical dimension. 5.6.3.2 Closed-Loop Control Circuits The principles for the identification of measuring circuits apply analogously to the identification of closed-loop control circuits on breakdown level 1. Every control loop and every closed-loop control circuit comprises measuring, control and positioning elements regardless of whether electrical, pneumatic, hydraulic or other items of equipment are used. Closed-loop controls are identified according to the controlled variable and not after the measuring circuits which serves the control or the final control element on which the control acts. 5.6.3.3 Signals and Signal Applications Breakdown level 3 is used to identify signals and their applications. For this purpose, data character B1 can contain X

Signal origin

Y

Signal application

Z

Gated signal

No generally valid rules have been made for signal and application areas. They must be established individually for different control and instrumentation concepts.
