Identification System for Combined Cycle Power Plant (KKS coding)

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.

Special Rules for Mechanical Engineering They should be established individually for different control and instrumentation concepts. This code is subject to agreement between the parties to the project. Data character F0 contains so called prefix number. Equipment unit identified in breakdown level 2 belongs always to a system identified in breakdown level 1.

B — Power transmission and auxiliarY electrical power supply H — Conventional heat generation Location Identification Identification of locations in structures, on floors and in rooms and also of fire areas. No one of these symbols can be omitted.

Types of Code and Breakdown Levels In consideration procedur 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: Feed water system Control and protection system for steam, LY. These three types of code use the same identification scheme, which is subdivided into four breakdown levels. C — Instrumentation and control systems The following principles direct for the designation of installation point in assembly units: Codes may be spaced by the insertion of blank spaces or interposing lines at predetermined points and by multiple- line notation: 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.


F General rules on other numbering code elements Fn, An, Bn.

The Equipment Unit identified in breakdown level 2 belongs always to the System designated in breakdown level 1. The second character of FN numbers the tagginy. 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.

But it is necessary to modificate the counting signs of breakdown level 1 – installation unit code. The systems and equipments which are controlled or monitored by the taggnig control equipment under supervision of the plant DCS shall also equip the KKS number. General Notes I – 5. On breakdown level 2, the individual windings are classified but tagting on a phase-specific basis by means of GT for transformer equipment and numbered starting on the high-voltage side.

The prefix symbols may be omitted if the information contents of the codes remain unambiguous.

AK over a separate position code is to be established, e. Inosanto Numbering System Inosanto Kali notes. Installation zone X Grid zone Installation zone Y. Where 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.


A Grid and distribution systems B Power transmission and auxiliary power supply C Instrumentation and control systems D Kkx and control systems E Conventional fuel supply and residues disposal F Handling of nuclear equipment G Water supply and disposal H Conventional heat generation J Nuclear heat generation K Nuclear auxiliary systems L Steam, water, gas cycles M Main machine sets N Process energy supply for external users e.

Requirements to be met by the Identification System 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 at that time.

The breakdown levels have the following structures: 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. The allowable notations are fixed. AL According to cubicles, divisions, sections etc.

Details of application are subject to agreement between the parties to the project. Signals and Signal Applications Breakdown level 3 is used to identify signals taggnig their applications. Types of Code and Breakdown Levels It is not allowed to use any other letters.

EB – Conditioning of signals related to single drive control.
