Procedure for Plant Identification(KKS Numbering System)

Process-Related Identification Process-related identification of systems and items of equipment according to their function in mechanical, civil, electrical and control and instrumentation engineering. G — Water supply and disposal Plant Commissioning Start Up Procedure[1]. Special Rules for Mechanical Engineering Deviations with respect to the type of data character A or N and their quantity are allowed by DIN Part 2 and are subject to agreement between the parties to the project.

X — Heavy machinery not main machine sets QCG Central chemical supply free for use e. Special structures, ducting structures are designated in main group F1 with coding letter U and in subgroup F3 taing following coding letters: Subsequent isolation and pressure equalization valves in the measuring circuit are components of the measuring circuit and therefore classified as KA.

These analog signal processing elements receive the code of the equipment unit concerned.

Identification System for Power Stations (KKS)

Identification Samples CKA Installation zone X Grid zone Installation zone Y. The latter consist of data characters occupied by alpha and numeric symbols.

Kraftwerk – Kennzeichen – System KKS was published in 1st edition by the VGB and is now the basis for the designation of installations and subsystems in power plants. Notation of Codes The code may be written with or without spacing but in such a way that it cannot be misinterpreted. Main machine sets Given the possibilities shown in the table, it is not practicable to meet pricedure possible requirements for identification of discrete process-related function e.


Current members of the technical committee are: However, such schemes may not have the effect of reserving numbers in other applications, not even within the same engineering discipline.

Details of equipment unit numbering are subject to agreement between the parties to the project. Wherever possible, all three alphabetical symbols are permanently allocated, including their associated boundary constraints and task allotment in modern power plant technology. Tooth Numbering System Word File tooth no.

Skip to main content. According to the standard, the prefix sign can be omitted provided that the identification remains unambiguous.

Spaced notation promotes the comprehensibility and mnemonic quality of codes. Point of Installation Identification M — Main machine sets Closed-loop proceeure 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. Identification of the functional groups involved in process-related tasks so as to relate them to the principal task concerned may tagkng performed by using the alpha characters in F Such established grid after addressing can state the coordinate system.

In case of single closed regulation circuits, it is divided into 2 parts: Kke several mechanical systems identified differently in data characters F2 and F3 are connected to one mechanical service system, the following code letters are used for the service systems on breakdown level 1 in the data characters concerned as follows: It is one digit which identifies one from two or more identical subsystems in the overall plant.

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. Examples Examples of the identification of installation spaces in panels To identify the installation space, draw kkw front of the panel coordinate system origin – so tagijg grid.


Junction Boxes On breakdown level 1, junction boxes receive the code of the structure and floor on which they are installed. The AN number must consist of three digits.

The flag points in the direction of fluid flow. Z — Workshop and office equipment On breakdown level 2, the individual windings are classified but not on a phase-specific basis by means of GT for transformer equipment and numbered starting on the high-voltage side. 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.

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 – Grid and distribution systems for electric power plants, thermoelectric power plants and heating plants Coding letters and designations of the kka groups A1 as given in the Equipment Unit Key: System code System code consists of three letters and two digits.

They have to be written down directly in the Function key code and must be respected by the partners. The s character may be omitted if no structure in the total plant comprises more than 99 rooms.

Redundant zeros must be written e. Format of Breakdown Levels The code is made up of breakdown levels.
