Introduction Identification System is based on the Kraftwerk – Kennzeichen – System KKS This System is the basis for the standard and clear identification of all installations and subsystems in power plant. Redundant zeros must be written, e. Identification Samples CKA AL According to cubicles, divisions, sections etc. Room Identification by Numbering Serial no. Main machine sets Given the possibilities shown in the table, it is not practicable to meet all possible requirements for identification of discrete process-related function e.

D — Loop control circuits In case for eg.

Procedure for Plant Identification(KKS Numbering System)

This rule does not refer to direct measurement circuits, which apply to technical installation and physical variable. Remember me Forgot password? Help Center Find new research papers in: Coding letters and designations of main groups B1 for components as given in the Component Key and for signals and signal applications: Generally valid rules on the use of FN numbering are not expedient.

Fire protection sections are identified according to the room identification. Gated analog signals representing physically similar direct measured variables are identified by means of a set number, e. Installation Unit Code Serial no.

If the letters available are insufficient, FN may be used. The additional code is used for the numbering of: L — Steam, water, gas cycles Equipment unit identified in breakdown level 2 belongs always to a system identified in breakdown level 1. Supply systems which serve only one equipment unit are identified on an equal footing as subsystems of the system in which they are installed. System numbering must consist of tagginy digits.


However the proxedure principles apply: Details of equipment unit numbering are subject to agreement between the parties to the project. 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. H — Conventional heat generation Inosanto Numbering System Inosanto Kali notes. 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 Where measured data are corrected e.

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.

All signals in such automatic regulation system in breakdown level KKS 0, taging, 2, are described identically. Coding letters and designations of the main groups A1 as given in the Tayging Unit Key: X — Heavy machinery not main machine sets Feed water system Tsgging and protection system for steam, LY. The systems and equipments which are controlled or monitored by the local control equipment under supervision of the plant DCS shall also equip the KKS number.

The origin and development of KKS B — Power transmission and auxiliarY electrical power supply Additional numbering code Serial no. Details of application are subject to agreement between the parties to the project.

KKS Identification System for Power Plants – Function and Type

EM – Conditioning of signals related to functional measurement group in digital system. Z — Workshop and office equipment Room Identification by Coordinates Serial no. However, provedure schemes may not have the effect of reserving numbers in other applications, not even within the same engineering discipline. When creating in DCS systems secondary variables of the taggiing technical installation that differs with counting sign for breakdown level 2, the same rules are to apply as for this variables created from the same installation.


EZ Protection For example: This code unit can be combined with any breakdown level as necessary for identification. AK over a separate position code is to be established, e. The contents of this designation in KKS, is left for coordination for particular power plant. 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.

It is not allowed to use any other letters. A2 identifies control and instrumentation functions e. Transducer Racks, Supports, Frames This auxiliary equipment is identified on breakdown level 1 using the code for the equipment location structure codewith the exception of auxiliaries for main machine sets and heavy machinery system code. Control and Instrumentation Equipment The AN number of breakdown level 2 is used to number the items of equipment classified in A1 and A2.

These three types of code use the same identification scheme, which is subdivided into four breakdown levels.
