The result was a series of operations whose sequence was often irrational. Structure Code Serial no. The latter consist of data characters occupied by alpha and numeric symbols.

System isolation valves for measuring circuits are identified on the level of the equipment unit code by skemens classifying letters AA. Format of Breakdown Levels This code is subject to agreement between the parties to the project. The alphabetical symbols of this breakdown level are used to classify and divide the overall plant into subsystems, systems or building structures.

These types of code cose distinguished by means of prefix and breakdown symbols. AN numbering may be consecutive or grouping. Click here to sign up.

The AN number of breakdown level 2 is used to number the items of equipment classified in A1 and A2. Bearing in mind the scale of power plants being built up to the early sixties, the Plant Identification Simeens AKS could be regarded as adequate for the needs of planning and construction engineers at that time. Mechanical Supports Supports may be identified using the system code or the structure code.

X — Heavy machinery not main machine sets C — Instrumentation and control systems If this is not the case, all floor numbering codes of the total plant must be written uniformly with three data characters in AN.

The data characters in parentheses may be omitted if the code remains unique. Steam, water, gas cycles Coe.

kk S — Ancillary systems N — Process energy supply for external users e. System One should remember, that the code of a system must consist of five symbols: Point of Installation Identification It is not allowed to use any other letters. They are generally identified after the system within the interfaces of which the sensor is installed.

Special Rules for Civil Siemns The prefix symbols may be omitted if the information contents of the codes remain unambiguous. Valves Valves are identified on the equipment unit level by the letters AA regardless of their type, design or actuator.

This applies analogously to supply systems. This is subject to agreement between the parties to the project. X and Y zones are outside the grid.

KKS Identification System for Power Plants – Function and Type

Identification of the functional groups involved in process-related tasks so as to relate them to the principal task siemena may be performed by using the alpha characters in F Types of Code and Breakdown Levels Format of Breakdown Levels The code is made up of breakdown levels.

Control and Instrumentation Equipment I – 5. Help Center Find new research papers in: Such established grid after addressing can state the coordinate system.

AK over a separate position code is to be established, e. Subgroups The classifying coding letters and designations are established on a non-project-specific basis in the KKS keys, namely as: Introduction Identification System is based on the Kraftwerk – Kennzeichen – Siemenss KKS This System is the basis for the standard and clear identification of all installations and subsystems in power plant.

In case for eg. 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. Special Rules cpde Mechanical Engineering Equipment unit code consists of 2 letters siemmens characters A1 and A23 digits data characters AN and sometimes 1 letter data character A3 which can be, and often is omitted.

APPENDIX I: KKS SYSTEM

Further applications are subject to agreement between the parties to the project. H — Subassemblies of main and heavy machinery Requirements to be met by the Identification System To perform the kls tasks the Identification system must be capable of satisfying the following requirements: Equipment Unit Identification In the process-related code which is the most important and mostly applied type of codes in every branch of engineering, the entire system is subdivided according to the function or process.

D — Loop control circuits Requirements to be met by the Identification System Data character G as well as data character F0 can be omitted in KKS sieemns the further part of designation will remain complete univocal. EM – Conditioning of signals related to functional measurement group in digital system.

Where an equipment unit serves as an interface between two or more systems, its system code is assigned on the originator principle, i. The contents of this designation in KKS, is left for coordination for particular power plant. A – Grid and distribution systems for electric power plants, thermoelectric power plants and heating plants M — Main machine sets Structure-related identification is expedient where different systems are held by shared supports.
