H — Conventional heat generation On breakdown level 2, the individual windings are classified but not on a phase-specific basis by means of GT for transformer equipment and numbered starting on the high-voltage side.

C — Instrumentation and control systems R — Gas generation and treatment Help Center Find new research papers in: Control and Instrumentation Equipment I – 5. Feed water system Control and protection system for steam, LY. 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 the classifying letters AA. In this application, however, a suitable identifier such as a prefixed Y should be used to indicate that a software coding unit is concerned, thus to rule out confusion with process-related codes.

Process-Related Identification Process-related identification of systems and items of equipment according to their function in mechanical, civil, electrical and control and instrumentation engineering. The additional code can be omitted. Equipment Unit-Specific Analog Signal Systrm and Measuring Circuits Equipment unit-specific analog signal processing elements comprise control and instrumentation equipment which is only provided iddntification one equipment unit such as control interface, protective logics, instruments in the feeder and command termination for final control elements.

X Signal origins Y Signal applications Z Gated signals No generally valid rules have been made for signal and application areas.


Mechanical Supports Supports may be identified using the system code or the structure code. Coding letters and designations of the main groups A1 as given in the Equipment Unit Key: X — Heavy machinery not main machine sets On breakdown level 2 supports should be identified by BQ.

The alphabetical symbols of this breakdown level are used to classify and divide the overall plant into subsystems, systems or building structures. Such established grid after addressing can state the coordinate system. System code System code consists of three letters and two digits.

Subsequent isolation and pressure equalization valves in the measuring circuit are components of the measuring circuit and therefore classified as KA. System One should remember, that the kms of a system must consist of five symbols: The data characters in parentheses may be omitted if the code remains unique. H — Subassemblies of main and heavy machinery Details of equipment unit numbering are subject to agreement between the parties to the project. Details of application are subject to agreement between the parties to the project.

Identification System for Combined Cycle Power Plant (KKS coding)

Exceptions systej junction boxes for main machine sets and heavy machinery, and junction boxes in electrical and control and instrumentation cubicles and cabinets; these are identified on breakdown level 1 according to the associated main machine or heavy machine and cubicle or cabinet respectively.

System-related identification is expedient where the supported items are positively assignable to one system. But it is necessary to modificate the counting signs of breakdown level 1 – installation unit code. Codes may be spaced by the insertion of blank spaces or interposing lines at identificafion points and by multiple- line notation: The origin and development of KKS Generally valid rules on the use of FN numbering are not expedient. Requirements to be met by the Identification System To perform the set tasks the Identification system must be capable of satisfying the following requirements: Component Code A component designated in breakdown level 3 is a part of equipment unit identified in breakdown level 2.

They are generally identified after the system within the interfaces of which the sensor is installed. Where measured data are corrected e. Control and Instrumentation Equipment 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 groups F1 by means of the following coding letters: It is not allowed to use any other letters.

In case of single closed regulation circuits, it is divided into 2 parts: Log In Sign Up.

Identificarion 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.

System numbering must consist of two digits. This code is subject to agreement between the parties to the project.

Steam, water, gas cycles Q. This rule does not refer to direct measurement circuits, which apply to technical installation and physical variable. EY – Conditioning of signals related to functional protection group of technical and electrical protection system of the unit.

The planning, construction and operation of power plants was based in the past on attempts to identify installations and parts thereof by means of differing incompatible systems. Equipment Pkwer Code Equipment Unit Code kkks of two letters, three digits and sometimes one additional letter data character A3 which can be omitted.
