KKS

Identification System for Power Stations

This booklet serves as an information tool about the KKS identification system for all types of power plants with the expection of nuclear power systems. It is not intended and it is not suitable as an instruction manual for KKS codification. For this purpose, please refer to project-specific "KKS Guidelines and Keys".

(IDENTIFICATION SYSTEM FOR POWER STATIONS)

Requirements

tion, operation, maintenance and waste management

In order to perform the set tasks the identification system must be capable of satisfying the following requirements:

The power plant identification· system is applied to clearly identify plants, systems, parts and components to their purpose, type and location.

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

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

The content is in accordance with "KKS Identification Systems for Power Stations " issued by VGB PowerTech Service GmbH Essen, Germany.

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

Consideration of national and international standards

Sufficient capacity for extension to accommodate new technologies

Non-language-based coding to ensure international usability

Consistent identification for planning, licensing, construe-

Application in computer data processing.

1.3. 1 Identification a~.:~d Type of Data Characters Table 1 summarizes the identification and type of data characters of the breakdown levels for all three different types of identification appearing in the KKS.

Structure and Application The KKS consists of three types of identification: The process-related code identifies installations and eguipment according to their assigned task in the power plant process

The location code identifies the rooms and floors, or other installation sites for installations and eguipment in building structures.

·'

Agreement on Break· down Level "G" - Overall Plant and F0 - Function Prefix Number

consecutive or grouping. - Numbering need not be continuous.

It may be necessary to identify units, non-unit specific plants or extension stages w ihin a power station, such that a clear and unambiguous distinction exists between them. This is provided by breakdown level 0 - Overall plant. This identification must be agreed upon by all parties concerned, regarding the contents and and typre of data character {A or N). Especially the identification of existing units has to be taken into account. The breakdown level "Overall plant" can be omitted when the designation remains unambiguous. If in the overall plant two or more identical plants or systerns are to be identified {e.g. 2 boiler plants, 2 gas turbines with attached el. generators and HRSGs, 2 structures with equal purpose) the prefix number F0 is used to distinguish between them. Each F0 number is valid only in the area of the Function concerned. O n no accounts it to be considered for the counting of system sections as parallel lines, data characters FN being used for this purpose.

- 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. - An application-speci fic scheme of numbering may be established . However, it has to be valid throughout all project disciplines in order of an unequivocal understand ing of the code. - Management systems {e.g. computer checking programs, allocation sheets) have to assure, that no double KKS numbers occur in the project and that no multiple KKS numbers are assigned to one item. - If necessary, subdivisio ns of number ranges in FN according to the division of work could be made. They have to be written down directly in the project-related Function key and must be respected by the partners involved.

General Rules on Numbering Code Elements (FN, AN, BN) - Numbering starts anew w hen one of the preceding code elements changes. - Numbering may be

2.3

for system code "Fo" and structures {F 1 = U) only. -The counting is not related to any geographical direction {e.g. not from west to east, not from north to south)

2.4

allocated KKS numbers for a project, if these numbers have been released for the project. -The original KKS number is still kept, even w hen another kind of equipment is used, provided that the function according to the KKS equipment unit code is not changed {e.g. substitution of a gate valve by a globe va lve).

2.5

j 12

Writing Modus of KKS Code Following structures of the KKS code are allowed: -in one line with space between Function Level, Equipment Unit Level {and Component Level) . e.g. 19PAB10 APOOl {-MOl ) - in two {three) li nes e.g. 19PAB10 A POOl {-MOl)

General Rules Regarding Direction of Numbering - Standard identi fications have priority in all cases. - Numbers are increasing in media or process flow direction . - Project counting directives referred to local layouts are related to breakdown level 11 G 11 , prefix number

Rules on Modifications and Cancellations of KKS Numbers - It is not allowed to change

2.6

General Rules on Process· related Identification - Piping & Instrument Diagrams (P&ID) are the basic

•"

-

documents (origins) for a process-related KKS coding. - Single line diagrams are the basic documents (origins) for a process-related KKS coding in electrical engineering. However, KKS codes for electrical consumers, measuring loops and items of I & C represented in

Function Diagr9ms are originated in P&IDs. - For other eng ineering activities (e.g. component engineering), KKS code must always be taken from the above mentioned basic documents. - In basic KKS documents (P&IDs, single line diagrams

and site layouts) the brea k down level 3 (component code) is never used . -The detailed KKS coding in process-related identification has to be made accord ing to the KKS-Application Commentaries, Part B1, B3 and B4 by VGB PowerTech GmbH.
