porcedure 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. Equipment unit identified in breakdown level 2 belongs always to a system identified in breakdown level 1.
Such modifications are subject prkcedure agreement between the parties to the project. In this type of code, the breakdown level 2 contains equipment unit code.
Cooling water system – Closed cooling water system – Compressed air system Rev. This code is subject to agreement between the parties to the project.
KKS Identification System for Power Plants – Function and Type
Introduction Identification System is based on the Kraftwerk – Kennzeichen – System KKS This System is the basis for the standard and clear identification of all installations and subsystems in power plant.
However, such schemes may not have the effect of reserving numbers in other applications, not taginy within the same engineering discipline. A2 identifies control and instrumentation functions e. The same applies to structures in civil engineering work.
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. F General prkcedure on other numbering code elements Fn, An, Bn. A – Grid and distribution systems for electric power plants, procevure power plants and heating plants Coding letters and designations of main groups B1 for components tsging given in the Component Key and for signals and signal applications: The AN number of breakdown level 2 is used to number the items of equipment classified in A1 and A2.
EZ Protection For example: Special guidelines apply to data characters G, F0 and A3.
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.
Measuring Circuits Measuring circuits comprise analog signal acquisition, conditioning, distribution and measured data recording and indicating processing elements. W — Renewable energy plants CF means the twelfth local measuring circuit of fluid flow the code CF12 is not correct.
F Point of Installation Identification This designation is used for the point of installation identification in assembly units for instrumentation and control system for e. The prefix number is used in cases when for instance in compass of one power unit appear two or more identical subsystems two boiler plants, two turbosets, etc. Point of Installation Identification H — Subassemblies of main and heavy machinery 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 acts.
Conventional heat generation Unit control system L. 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.
Identification System for Power Stations (KKS)
Hydrotest Procedure for Pipeline example. 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. 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.
EY – Conditioning of signals related to functional protection group of technical and electrical protection system of the unit. Treatment system GUA Rainwater collection and drainage systems free for use e. Numbering starts anew when one of the preceding code elements changes. The direction of numbering is vertical from the lowermost floor upwards.
Details of application are subject to agreement between the parties to the project. 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.

X special structures, Y bridge structures, Z ducting structures. The additional code can be omitted. Locations, for example, coordinates, racks and positions in cubicles etc. F Process-related identification In this type of identification the entire system is subdivided according to the function or process, since, whether for mechanical, electrical, control of civil engineering, the equipment units and components must be identifiable in relation to procedhre process.
Procsdure structures, ducting structures are designated in main group F1 with coding letter U and in subgroup F3 with following coding letters: AM Mixers, agitators AN Compressor, fans and blower unit AP Pump units AS Adjusting and tensioning equipment for non-electrical variables to be applied only, if the actuator forms itself a constructive unit with another equipment unit AT Cleaning, drying, filtering and separating equipment and trap, excl.
The alphabetical symbols of this breakdown level are used to classify and divide the overall plant into subsystems, systems or building structures. G — Water supply and disposal The result was a series of operations whose sequence was often irrational.
A uniform identification structure, with a maximum of four breakdown levels, was created for all three types; the units referred to becoming smaller from left to right. F3 of the principal process-related task. F Equipment Unit Key, groups A1:
