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.

The latter consist of data characters occupied by alpha and numeric symbols. Such modifications are subject to agreement between the parties to the project. 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.
Increased unit sizes, higher rates of automation and further developments in power-plant technology, coupled with the demands made on classification systematics by power plant operators, all called for a uniform and total solution of the classification problem. C — Direct measuring circuits Usually the code is written above the line: They are made up of classifying and numbering code elements.
Room Identification by Numbering Serial no. Drains and vents are identified as far as the final isolation element — including double valves — or as far as the open outlet as part of the drained or vented system originator principle.
Identification System for Combined Cycle Power Plant (KKS coding)
Skip to main content. 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. 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. Steam, water, gas cycles CJA common to H.
Format of Code I – 2.
The outdoor area is designated in the breakdown level 1 by symbols: 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. Valves Valves are identified on the equipment unit level by the letters AA regardless of their type, design or actuator.
Data character G as well as data character F0 can be omitted in KKS if the further part of designation will remain complete univocal. System numbering must consist of two digits.
Room Identification by Coordinates Serial no. Special Rules for Mechanical Engineering However, such schemes may not have the effect of reserving numbers in other applications, not even within the same engineering discipline.
C — Instrumentation and control systems Component Code A component designated in breakdown identofication 3 is a part of equipment unit identified in breakdown level 2.

In the meantime, the AKS has been adopted as the main system of identification in a number of conventional and nuclear plants. N — Process energy supply for external users e. These three types of code use the same identification scheme, which is subdivided into four breakdown levels.
D — Loop control circuits Mechanical Service Systems Mechanical service systems which serve more than one main group identified on breakdown level 1 are identified as auxiliary or ancillary systems in separate main groups F1 by means of the following coding letters: On breakdown level 2 supports should be identified by BQ. Identification of the functional groups involved in process-related tasks so as to relate them to the principal task concerned may be performed by using the alpha characters in F L — Steam, water, gas cycles Installation Unit Code Serial no.
For example we can identify here: H — Conventional heat generation V Lubricant supply system W Sealing fluid supply system X Fluid supply system for control and protection equipment.
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.
In this type of code, the breakdown level 2 contains equipment unit code. EB – Conditioning of signals related to single drive control.
X — Heavy machinery not main machine sets Codes may be spaced by the insertion of blank spaces or interposing lines at predetermined points and by multiple- line notation: Identification Samples CKA
