The KKS system is a classification system for the complete power plant and its components and provides a common language for the designer.

Equipment unit code consists of 2 letters data lrocedure A1 and A23 digits data characters AN tagginb sometimes 1 letter data character A3 which can be, and often is omitted.
Due to the size of power plants and the fact that the large number of parties participating are all in different locations, communication problems arise which can incur costs which cannot be estimated in advance. Installation zone X Grid zone Installation zone Y. X special structures, Y bridge structures, Z ducting structures. This prefix sign is omitted when there is absolutely no ambiguity in layout documents.
Identification System for Combined Cycle Power Plant (KKS coding)
If several process-related systems are situated in one structure we designate this structure according to the main, most important system. F Equipment Unit Key, groups A1: Special Rules for Mechanical Engineering Structure Code Serial no. The AN number of breakdown level 2 is used to number the items of equipment classified in A1 and A2. The identification letters now used for the Point of installation identification tagginv the breakdown level FUNCTION are the same as those for the process-related identification.
AM Mixers, agitators AN Compressor, fans and blower unit AP Pump units AS Adjusting and tensioning equipment for non-electrical variables to be ksk only, if the actuator forms itself a constructive unit with another equipment unit AT Cleaning, drying, filtering and separating equipment and trap, excl. G — Electrical devices The s character may be omitted if no structure in the total plant comprises more than 99 rooms.
EA – Conditioning of signals related to functional control group. A — Mechanical equipment Junction Boxes On breakdown level 1, junction boxes receive the code of the structure and floor on which they are installed.

In case of single closed regulation circuits, it is divided into 2 parts: When technical installations differs only with counting signs of installation it is necessary to assign to a secondary variable counting signs like for one of those installations e.
They are made up of classifying and numbering code elements. According to the standard, the prefix sign can be omitted provided that the identification remains unambiguous. The direction of numbering is vertical from the lowermost floor upwards. Coding letters and designations of the main groups F1 as given in the Function Key: Help Center Find new research papers in: The prefix symbols may be omitted if the information contents of the codes remain unambiguous.
These analog signal processing elements receive the code of the equipment unit concerned. The result was a series of atgging whose sequence was often irrational.
F General rules on other numbering code elements Fn, An, Bn. Because relevant design progress have been done too much. E — Binary and analog signal and variable conditioning Plant Commissioning Start Up Procedure.
Closed-Loop Control Circuits The principles for the identification of measuring circuits apply analogously to the identification of closed-loop control circuits on breakdown level 1.
Valves Valves are identified on the equipment unit level by the letters AA regardless of their type, design or actuator. Identification in data character A2 is governed by the physical variable. Data characters AN indicate counting in the horizontal direction columns numbering.
N — Process energy supply for external users e. All signals in such automatic regulation system in breakdown level KKS 0, prpcedure, 2, are described identically.
Read from left to right no data characters may be omitted. Calculation of new value on base of 2 variables, e.
Procedure for Plant Identification(KKS Numbering System)
Usually the code is written above the line: Any combination of alpha and numerical symbols appropriate to the requirements is acceptable for the identification of connections.
Fictitious rooms in structures may be identified by numbering or coordinate systems. Originally the titles of taggijg breakdown levels were based on the process-related code:
