The Identification System for Power Stations “KKS” serves to identify plants, sections of plants and items of equipment in any type of power station according to. 71 Page Identification System KKS Part 1 – General 4/ II – . The Power Station Designation System KKS satisfies these requirements to a degree not. KKS Identification System for Power – Download as PDF File .pdf) or view presentation slides online.

Where 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: System isolation valves for measuring circuits are identified on the level of the equipment unit code by the classifying letters AA.
Identification System for Power Stations (KKS)
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. However, such schemes may not have the effect of reserving numbers in other applications, not even within the same engineering discipline. AK over a separate position code is to be established, e. W — Renewable energy plants Requirements to be met by the Identification System To perform the set tasks the Identification system must be capable of satisfying the following requirements: Coding letters and designations of the main groups F1 as given in the Function Key: Rules on the Keys Control and Instrumentation Equipment Additional numbering code Serial no.
For example maximum of a few direct measured variables: 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.
Identification System for Combined Cycle Power Plant (KKS coding)
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. These types of code are distinguished by means of prefix and breakdown symbols.
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 in data character A2 is governed by the physical variable. Measuring circuits are identified according to the system within the interfaces of which the sensor is installed. Current members of the technical committee are: If several process-related systems are situated in one structure we designate this structure according to the main, most important system. 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.
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: Special Rules for Civil Engineering F3 of the principal process-related task. A breakdown level 2 is used to identify the installation space. G — Water supply and disposal The outdoor area is designated in the breakdown level 1 by symbols: The next counting signs of the circuit does not change when is creating only one combined variable.
The second character of FN numbers the cubicles. Modern methods of digital systems programming and ability of efficient use of technical documentation require to use the concept of functional group positions A1 and A2 and number of the group positions An – three numerals depending on degree of complexity of automatic analog control system.
Junction Boxes On breakdown level 1, junction boxes receive the code of the structure and floor on which they are installed. Special structures, ducting structures are designated in main group F1 with coding letter U and in subgroup F3 with following coding letters: Fictitious rooms in structures may idntification identified by numbering or coordinate systems. The latter consist of data characters occupied by alpha and numeric symbols.
System-related identification is expedient where the supported items are positively assignable to one system. All signals in such automatic regulation system poweg breakdown level KKS 0, 1, 2, are described identically. Installation zone X Grid zone Installation zone Y. The additional code can be omitted.
On breakdown level 2 supports should be identified by BQ.
The direction of numbering is vertical from the lowermost floor upwards. If this is not the case, all floor numbering codes of the total plant must be written uniformly with three data characters in AN. It is a common practice to apply s grouping: Structure Code Serial no.
EA – Conditioning of signals related to functional control group. Identification Samples CKA H — Conventional heat generation Remember me on this computer.
Exceptions are junction boxes for main machine sets and heavy machinery, and junction boxes in electrical and control and instrumentation cubicles and cabinets; these are identified on idehtification level 1 according to the associated main machine or heavy machine and cubicle or cabinet respectively.
M — Main machine sets Steam, water, gas cycles Q.

Feed water system Control and protection system for steam, LY. S — Ancillary systems Mechanical Supports Supports may be identified using the system code or the structure code. YB71 XB72 Control room; close, down Redundant zeros must be written.
