KKS Identification System for Power Plants – eBook

Remember me on this computer. These types of code are distinguished by means of prefix and breakdown symbols. The second character of FN numbers the cubicles. In case for eg. M — Main machine sets Types of Code and Breakdown Levels Equipment unit code consists of 2 letters data characters A1 and A23 digits data characters AN and sometimes 1 letter data character A3 which can be, and often is omitted.

Total plant Serial no. The individual breakdown levels are differently identificatioon. Installation Unit Code Serial sytem.

E — Binary and analog signal and variable conditioning The additional code is used for the numbering of: 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 poaer the parties to the project. For this purpose, data character B1 can contain: The origin of the letters used in it is in German language, namely: System-related identification is expedient where the supported items are positively iedntification to one system.

Rules on the Keys Where individual structures for which separate structure codes exist are combined identificatiln form one structure, that structure is given the code of the most important individual structure.


They are generally identified after the system within the interfaces of which the sensor is installed. On breakdown level 2, transducer racks, supports and frames are identified by means of GZ.

Equipment unit classification Serial no. If several process-related systems are situated in one structure we designate this structure according to the main, most important system.

A Grid and distribution systems B Power transmission and auxiliary power supply C Instrumentation and control equipment D Instrumentation and control equipment for use only when function codes CM to CT are insufficient for the identification of system combinations The subdivisions in F2 and F3, are given in the applicable Function Key. Subdivide for this aim the panel elevation into planes: This applies analogously to supply systems.

G — Water supply and disposal The next counting signs of the circuit does not change when is creating only one combined variable.

B — Power transmission and auxiliarY electrical power supply QCG Central chemical supply free for use e.

There are also cases of deviations consisting in using the dividing symbol twice, and AN, e. YB71 XB72 Control room; close, down It is one digit which identifies one from two or more identical subsystems in the overall plant.

Measuring circuits are identified according to the system within the interfaces of which the sensor is installed. Z — Workshop and office equipment Shared equipment Combined electrical and control and instrumentation equipment Combined electrical ,ks control and instrumentation equipment, with or without a power unit e.

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.


Increased unit sizes, higher rates of automation and further developments in power-plant technology, coupled with the demands made on classification systematics by power powerr operators, all called for a uniform and total solution of the classification problem. Valves Valves are identified on the equipment unit level by the letters AA regardless of their type, design or actuator. Special guidelines apply to data characters G, F0 and A3.

G — Electrical devices Equipment Unit Code Equipment Unit Code identificatoin of two letters, three digits and sometimes one additional letter data character A3 which can be omitted. Transducer Racks, Supports, Frames This auxiliary equipment is identified on breakdown level 1 using the code for the equipment location structure codewith the exception of auxiliaries for main machine sets and heavy machinery system code.

N — Process energy supply for external users e. The alphabetical symbols of this breakdown level are used to classify and divide the overall plant into subsystems, systems or building structures. The AN number must consist of three digits.
