APPENDIX I: KKS SYSTEM

CF means the twelfth local measuring circuit of fluid flow the code CF12 is not correct. The origin and development of KKS It is absolutely essential for cose parties participating in the construction and operation of a power plant to agree upon a standard system for the designation and classification of the plant, its part and components.

The origin of the letters used in it is in German language, namely: In case for eg. System numbering must consist of two digits. All signals in such automatic regulation system in breakdown level KKS 0, 1, 2, are described identically. EA – Conditioning of signals related to functional control group.

QCU Central chemical supply free for use e. They are generally identified after the system within the interfaces of which the sensor is installed. Where measured data are corrected e. Safety equipment, consisting of safety valves and their associated piping, are assigned to the system to which they are connected. Measuring Circuits Measuring circuits comprise analog signal acquisition, conditioning, distribution and measured data recording and indicating processing elements.

A – Grid and distribution systems for electric power plants, thermoelectric power plants and heating plants Component Code A component designated in breakdown level 3 is a part of equipment unit identified in breakdown level 2. Details of equipment unit numbering are subject to agreement between the parties to the project.

This rule does not refer to direct measurement circuits, which apply to technical installation and physical variable.

Usually the code is written above the line: On breakdown level 2 supports should be identified by BQ. Structure-related identification is expedient where different systems are held by shared supports. The additional code can be omitted. These types of code are distinguished by means of prefix and breakdown symbols. B — Power transmission and auxiliarY electrical power supply For this purpose, data character B1 can contain: Spaced notation promotes the comprehensibility and mnemonic quality of codes.

APPENDIX I: KKS SYSTEM

Special structures, ducting structures are designated in main group F1 with coding letter U and in subgroup F3 with following coding letters: Control coode Instrumentation Equipment Identification of the functional groups involved in process-related tasks siiemens as to relate them to the principal task concerned may be performed by using the alpha characters in F The data characters in parentheses may be omitted if the code remains unique.

Physically separate rooms in structures are identified by numbering, grid squares in the outdoor area by coordinates. Core code System code consists of three letters and two digits.

Requirements to be met by the Identification System Room Identification by Coordinates Serial no. Equipment Unit Code Equipment Unit Code consists of two letters, three digits and sometimes one additional letter data character A3 which can be omitted.

Installation Unit Code Serial no. Click here to sign up.

A breakdown level 2 is used to identify the installation space. 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.

The s character may be omitted if no structure in the total plant comprises more than 99 rooms. Codes may be spaced by the insertion of blank spaces or interposing lines at predetermined points and by multiple- line notation: E — Binary and analog signal and variable conditioning Mechanical Supports Supports may be identified using the system code or the structure code.

In this type of code, the breakdown level 2 contains equipment unit code. M — Main machine sets A — Mechanical equipment Such established grid after addressing can state the coordinate system.

KKS Identification System for Power Plants – Function and Type

Read from left to right no data characters may be omitted. Valves Valves are identified on the equipment unit level by the letters AA regardless of their type, design or actuator.

On breakdown level 2, transducer racks, supports and frames are identified by means of GZ. If this is not the case, all floor numbering codes of the total plant must be written uniformly with three data characters in AN. Types of Code and Breakdown Levels In consideration of the various siemmens placed on the identification of plants, sections of plants and items of equipment in power station, KKS has three different types of code:
