It is one digit which identifies one from two or more identical subsystems in the overall plant.

Junction Boxes On breakdown level 1, junction boxes receive the code of the structure and floor on which they are installed. It is a common practice to apply a grouping numbering of equipment units: Types of Code and Breakdown Levels In consideration of 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: Physically separate rooms in structures are identified by numbering, grid squares in the outdoor area by coordinates.

This code unit can be combined with any breakdown level as necessary for identification.

Kkss rule does not refer to direct measurement circuits, which apply to technical installation and physical variable. E — Binary and analog signal and variable conditioning Steam, water, gas cycles CJA common to H.

The allowable notations are fixed. Structure Code Serial no.

Numbering begins anew for each structure. EZ Protection For example: Remember me on this computer. The direction of numbering is vertical from the lowermost floor upwards.

Safety equipment, consisting of safety valves and their associated piping, are assigned to the system to which they are connected. For example maximum of a few direct measured variables: Requirements to be met by the Identification System If this is not the case, all floor numbering codes of the total plant must be written uniformly with three data characters in AN.


Special Rules for Mechanical Engineering I – 5. Equipment Unit Code Equipment Unit Code consists of two letters, three digits and sometimes one additional letter data character A3 which can be omitted. Supply systems which serve only one equipment unit are identified on an poaer footing as subsystems of the system in which they are installed.

Current members of the technical committee identificayion The origin and development of KKS It is absolutely essential for the 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.

Measuring Circuits Measuring circuits comprise analog signal acquisition, conditioning, distribution and measured data recording and indicating processing elements. Special structures, ducting structures are designated in main group F1 with coding letter U and in subgroup F3 with following coding letters: L — Steam, water, gas cycles However the following principles apply: X and Y zones are outside the grid. V Lubricant supply system W Sealing fluid supply system X Fluid supply system for control and protection equipment.

Usually the code is written above the line: AN numbering may be consecutive or grouping. The alphabetical symbols of this breakdown level are used to classify and divide the overall plant into subsystems, systems or building structures. 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.

Further applications are subject to agreement between the parties to the project. identificafion

Identification System for Power Stations (KKS)

R — Gas generation and treatment The flag points in the direction of fluid flow. Installation Unit Code Serial no. The next counting signs of the circuit does not change when is creating only one combined variable. Location Identification Identification of locations in structures, on floors and in rooms and also of fire areas. Total plant Serial no.


Data character G as well as data character F0 can be omitted in KKS if the further part of designation will remain complete univocal. A working party, consisting of planners, operating companies, authorized inspectors and other authorities, was set up in with the task of finding such a solution.

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 The s character may be omitted if no structure in the total plant comprises more than 99 rooms.

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.

Subdivide for this aim the panel elevation into planes: D — Control systems The contents of this designation in KKS, is left for coordination for particular power plant. Wherever possible, all three alphabetical symbols are permanently allocated, including their associated boundary constraints and task allotment in modern power plant technology.

Coding letters of the main groups F1 are specified on next and the subdivisions in F2 and F3 are given in the present chapter II.
