KKS Identification System for Power Plants – Function and Type
AM Mixers, taggjng 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. In the meantime, the AKS has been adopted as the main system of identification in a number of conventional and nuclear plants.
F Process-related Designation The breakdown levels have the following structure: QCG Central chemical supply free for use e. QCU Central chemical supply free for use e. A — Mechanical equipment Types of Tqgging and Breakdown Levels B — Mechanical equipment The flag points in the direction of fluid flow.
Code 0 Identification Common for the plant unit: Notation of Codes The code may be written with or without spacing but in such a way that it cannot be misinterpreted.
We share information about your activities on the site with our partners and Google partners: Equipment unit code consists of 2 letters data characters A1 and A23 procedjre data characters AN and sometimes 1 letter data character A3 which can be, and often is omitted. Proceduge additional code is used for the numbering of: FN numbering is governed by the following principles: Plant Commissioning Start Up Procedure.
The next counting signs of the circuit does not change when is creating only one combined variable. Equipment Unit Identification In the process-related code which is the most important and mostly applied type of codes in every branch of engineering, the kos system is subdivided according to the function or process. B — Power transmission and auxiliarY electrical power supply F Equipment Unit Key, groups A1: For example maximum of a few direct measured variables: X and Y zones are outside the grid.

Calculation of new value on base of 2 variables, e. G — Water supply and disposal Identification of the functional groups involved in process-related tasks so as to relate them to the twgging task concerned may be performed by using the alpha characters in F F General rules on other numbering code elements Fn, An, Bn. Prefix symbol for point of installation code Designation of Entire Plant Units Designation of Units Groups Systems classifying System numbering Break down symbol “full stop” it can be omitted Installation space code – vertical subdivision where needed Additional code – identification of kke components where needed 1.
Redundant zeros must be written, e. Total plant Serial no. Z — Workshop and office equipment This is subject to agreement between the parties to the project. Format of Code I – 2. The outdoor area is designated in the breakdown level 1 by symbols: 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.
Procedure for Plant Identification(KKS Numbering System)
System-related identification is expedient where the supported items are positively assignable to one system. 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.
Redundant zeros must be written. proedure
The origin of the letters used in it is in German language, namely: Examples Examples of the identification of installation spaces in panels To identify the installation space, draw on front of the panel coordinate system origin – so called grid. Subsequent isolation and pressure equalization valves in the measuring circuit are components of the measuring circuit and therefore classified as KA. The grid sizes and the meaning and type of the data characters A or N are subject to agreement between the parties to the project.
A Grid and distribution systems B Power transmission and auxiliary power supply C Instrumentation and control systems D Instrumentation and control systems Pdocedure Conventional fuel supply and residues disposal F Handling of nuclear equipment G Water supply and disposal H Conventional heat generation J Nuclear heat generation K Nuclear auxiliary systems L Steam, water, gas cycles M Main machine sets N Process energy supply for external users e.
Format of Breakdown Levels The following principles direct for the designation of installation point in assembly units: P — Cooling water systems 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.
