The KKS system is a classification system for the complete power plant and its components and provides a common language for the designer. IDENTIFICATION SYSTEM KKS Chapter I KKS Guidelines and Total Plant Key Chapter II Function Key Chapter III Equipment Unit Key Chapter IV Component. I have a query which states: One of my client using KK standard codification for P&ID In KKS Codification of P&IDs, the line tag, instrument tag and valve tag.

Redundant zeros must be written e.
Current members of the technical committee are: This code unit can be combined with any breakdown level as necessary for identification. The prefix symbols may be omitted if the information contents of the codes remain unambiguous. Subdivide for this aim the panel elevation into planes: The numerical digits count and subdivide the unit e.
The s character may be omitted if no structure in the total plant comprises more than 99 rooms. Codicication use for any intended purpose is subject to agreement between the codificatio to the project.
KK standard codification
The contents of this designation in KKS, is left for coordination for particular power plant. A breakdown level 2 is used to identify the installation space.
EZ Protection For example: Q — Auxiliary systems Log In Sign Up. General Notes I – 5.
Component codification and identification systems|INIS
Coding letters of the main groups F1 are specified on next and the subdivisions in F2 and F3 are given in the present chapter II. Order according to voltage levels, counted from higher voltages to lower. Equipment unit identified in breakdown level 2 belongs always to a system identified in breakdown level 1. Assignment of System Codes to Mechanical Equipment and Measuring Circuits Equipment units are identified according to the system within the interfaces of which they are located. Control and Instrumentation Equipment The additional code can be omitted.
Identification System for Combined Cycle Power Plant (KKS coding)
FN numbering is governed by the following principles: Steam, water, gas cycles CJA common to H. Closed-loop controls are identified according to the controlles variable and not after the measuring circuits which serves the control or the final control element on which the control acts.
They should be established individually for different control and instrumentation concepts. Notation of Codes The code may be written with or without codificahion but in such a way that it cannot be misinterpreted.
YB71 XB72 Control room; close, down Equipment unit code consists of 2 letters data characters A1 and A23 digits data characters AN and sometimes 1 codiifcation data character A3 which can be, and often is omitted. Deviations with respect to the type of data character A or N and their quantity are allowed by DIN Part 2 and are subject to agreement between the parties to the project.
Requirements to be met by the Identification System To perform the set tasks the Identification system must be capable of satisfying codiffication following requirements: When technical installations differs only with counting signs of installation it is necessary to assign to a secondary variable counting signs like for one of those installations e. Types of Code and Breakdown Levels R — Gas generation and treatment S — Ancillary systems EA – Conditioning of signals related to functional control group.
System code System code consists of three letters and two digits.
