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.
Bearing in mind the scale of power plants being built up to the early sixties, the Plant Identification System AKS could be regarded as adequate for the needs of planning and construction engineers jks that time. Coeification rule does not refer to direct measurement circuits, which apply to technical installation and physical variable. Additional numbering code Serial no. Mechanical Service Systems Mechanical service systems which serve more than one main group identified on breakdown level 1 are identified as auxiliary or ancillary systems in separate main cldification F1 by means of the following coding letters: Requirements to be met by the Identification System H — Conventional heat generation 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: It is not allowed to use any other letters. G — Water supply and disposal Usually the code is written above the line: 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 A2 identifies control and instrumentation functions e.
Special Rules for Mechanical Engineering Regulation part is described in level 1 by process-related installation, and level 2 by the controlled parameter – control part is described by executive device e.
KK standard codification
Codificattion individual structures for which separate structure codes exist are combined to form one structure, that structure is given the code of the most important individual structure.
There are also cases of deviations consisting in using the dividing symbol twice, and AN, e.
AL According to cubicles, divisions, sections etc. The flag points in the direction of fluid flow. The latter consist of data characters occupied by alpha and numeric symbols.
Conventional heat generation Unit control system L. The allowable notations are fixed. A – Grid and distribution systems for electric power plants, thermoelectric power plants and heating plants Measuring circuits are identified according to the system within the interfaces of which the sensor is installed. Assignment of System Codes to Mechanical Equipment and Measuring Circuits Equipment units are identified cpdification to the system within the interfaces of which they are located.
Their use for any intended purpose is subject to agreement between the parties to the project. Installation zone X Grid zone Installation zone Y. When creating in DCS systems secondary variables of the same 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.
Identification System for Combined Cycle Power Plant (KKS coding)
X and Y zones are outside the grid. Control and Instrumentation Equipment Total plant Serial no. Junction Boxes On breakdown level 1, junction boxes receive the code of the structure and floor on which they are installed. Format of Code I – 2. Gated analog signals representing physically similar direct measured variables are identified by means of a set number, e.
EB – Conditioning of signals related to single drive control. 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 lks.
Thus for example, it may be necessary to use items which are 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.
Steam system common to LA. Steam, water, gas cycles CJA common to H.
The prefix number is used in cases when for instance in compass of one power unit codiification two or more identical subsystems two boiler plants, two turbosets, etc.
Skip to main content. If this is not the case, all floor numbering codes of the total plant must be written uniformly with three data characters in AN.
