On breakdown level 2 supports should be identified by BQ.

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 station, KKS has three different types of code: However, such schemes may not have the effect of reserving numbers in other applications, not even within the same engineering discipline.

Identification in data character A2 is governed by the physical variable. Order according to voltage levels, counted from higher voltages to lower.

Format of Breakdown Levels The code is made up of breakdown levels. Thus for example, it may be necessary to use items which odentification 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.

X special structures, Y bridge structures, Z ducting structures. Rules on the Keys AN numbering may be consecutive or grouping.

This draws clear divisions between power plant installations and systems, and takes full account of the needs of manufacturers, operators, inspectors and other authorities as well as the technical requirements of the mechanical engineering, process engineering, civil engineering, and electrical and control engineering sectors. The outdoor area is designated in the breakdown level 1 by symbols: Subgroups The classifying coding letters and designations are established on a non-project-specific basis in sysyem KKS keys, namely as: Equipment unit code consists of 2 letters data characters A1 and A23 digits data characters AN and sometimes 1 letter data character A3 which can be, and often is omitted.


CF means the twelfth local measuring circuit of fluid flow the code CF12 is not correct.

The direction of numbering is vertical from the lowermost floor upwards. Safety equipment, consisting of safety valves and their associated piping, are assigned to the system to which they are connected.

Steam, water, gas cycles CJA common to H. Function-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.

Measuring Transformers The types of measuring transformers as well as their quantities in the given system are identified in breakdown level 2 by letters GT and three digits. Coding letters and designations of the main groups A1 as given in the Equipment Unit Key: In the meantime, the AKS has been adopted as the main system of identification in a number of conventional and nuclear plants.


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 The numerical digits count and subdivide the unit e. M — Main machine sets E — Binary and analog signal and variable conditioning Feed water system Sealing fluid supply system for LB.

Room Identification by Coordinates Serial no. YB81 XB82 Auto; close, down R — Gas generation and treatment In such instances the first character of FN has a classifying purpose.

This code is subject to agreement between the parties to the project. Room Identification by Numbering Serial no.

Identification System for Combined Cycle Power Plant (KKS coding)

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.

Subsequent isolation and pressure identificztion valves in the measuring circuit are components of the measuring circuit and therefore classified as KA.

It is not allowed to use any other letters. A Grid identificztion distribution systems B Power transmission and auxiliary power supply C Instrumentation and control equipment D Instrumentation and control equipment for use only when function codes CM to CT are insufficient for the identification of system combinations The subdivisions in F2 and F3, are given in the applicable Function Key.
