Sytem modifications are subject to agreement between the parties to the project. YB71 XB72 Control room; close, down Fictitious rooms in structures may be identified by numbering or coordinate systems. 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 entire system is subdivided according to the function or process.

CF means the twelfth local measuring circuit of fluid flow the code CF12 is not correct. Control and Instrumentation Equipment X Signal origins Y Signal applications Z Gated signals No generally valid rules have been made for signal and application areas.

V Lubricant supply system W Sealing fluid supply system X Fluid supply system for control and protection equipment. Equipment Unit-Specific Analog Signal Processing and Measuring Circuits Equipment unit-specific syshem signal processing elements comprise control and instrumentation equipment which is only provided for one equipment unit such as control interface, protective logics, instruments in the feeder and command termination for final control elements.

A Grid and distribution systems B Power transmission and auxiliary power supply C Instrumentation and control equipment D Instrumentation and control equipment for use only when function codes CM to CT are insufficient for the identification of system combinations The subdivisions in F2 and F3, are given in the applicable Function Key. Steam system common to LA. Process-Related Identification Process-related identification of systems and items of equipment according to syystem function in mechanical, civil, electrical and control and instrumentation engineering.


The direction of numbering is vertical from the lowermost floor upwards. Physically separate rooms in structures are identified by numbering, grid squares in the outdoor area by coordinates.

Remember me on this computer.

Main machine sets common to L. These types of code are distinguished by means of prefix and breakdown symbols.

Help Center Find new research papers in: Spaced notation promotes the comprehensibility and mnemonic quality of codes. W — Renewable energy plants The Equipment Unit identified in breakdown level 2 belongs always to the System designated in breakdown level 1. EM – Conditioning of signals related to functional measurement group in digital system. If necessary, further grouping can be performed by using FN.

KKS Identification System for Power Plants – eBook

The contents of this designation in KKS, is left for coordination for particular power plant. EY – Conditioning of signals related to functional protection group of technical and electrical protection system of the unit. The additional code can be omitted. The origin of the letters used in it is in German language, namely: If several process-related systems are situated in one structure we designate this structure according to the main, most important system.

Measuring circuits are identified according to the system within the interfaces of which the sensor is installed.

Safety equipment, consisting of safety valves and their associated piping, are assigned to the system to which they are connected. Enter the email address you signed up with and we’ll email you a reset link. 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.


Data character F0 contains so called prefix number. But it is necessary to modificate the counting signs of breakdown level 1 – installation unit code. Read from left to right no data characters may be omitted. Special Rules for Civil Engineering Redundant zeros must be written. The numerical digits count and subdivide the unit e. Log In Sign Up. However the following principles apply: Installation Space Code Serial no. 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.

Such established grid after addressing can state the coordinate system. Click here to sign up. Skip to main content. Redundant zeros must be written e.

Identification System for Combined Cycle Power Plant (KKS coding)

The outdoor area is designated in the breakdown level 1 by symbols: Control and Instrumentation Equipment I – 5. Equipment unit classification Serial no. P — Cooling water systems 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: 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.

All signals in identificatoon automatic regulation system in breakdown level KKS 0, 1, 2, are described identically.
