Kazracage 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.

F Process-related identification In this type of identification the entire system is subdivided according to the function or process, since, whether for mechanical, electrical, control of civil engineering, the equipment units and components must be identifiable in relation to the process.

In the meantime, the AKS has been adopted as the main system of identification in a number of conventional and nuclear plants. Data character G as well as data character F0 can be omitted in KKS if the further part of designation will remain complete univocal.

The result was a series of operations whose sequence was often irrational. The next counting signs of the circuit does not change when is creating only one combined variable. However, such schemes may not have the effect of reserving numbers in other applications, not even within the same engineering discipline.

The first digit is often used to point the kind sort of component designated in B1 B2. The data characters in parentheses may be omitted if the code remains unique. Notation of Codes The code may be written with or without spacing but in such a way that it cannot be misinterpreted. V Lubricant supply system W Sealing fluid supply system X Fluid supply system for control and protection equipment. Introduction Breakdown level 1 System function Serial no.

However, such schemes may not have the effect of reserving numbers in other applications, not even within the same procfdure discipline. Such established grid after addressing can state the coordinate system. However the following principles apply: Calculation of new value on base of 2 variables, e.

Feed water system Sealing fluid supply system for LB. Skip to main content. 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.

There prcoedure also cases of deviations consisting in using the dividing symbol twice, and AN, e. The latter consist of data characters occupied by alpha and numeric symbols. A Grid and distribution systems B Power transmission and auxiliary power supply C Instrumentation and control systems D Instrumentation and control systems Taggiing Conventional fuel supply and residues disposal F Handling of nuclear equipment G Water supply and disposal H Conventional heat generation J Nuclear ptocedure generation K Nuclear auxiliary systems L Steam, water, gas cycles M Main machine sets N Process energy supply for external users e.

Subgroups The procedurw coding letters and designations are established on a non-project-specific basis in the KKS keys, namely as: Component Code A component designated in breakdown level 3 is a part of equipment unit identified in breakdown level 2.

A — Mechanical equipment Physically separate rooms in structures are identified by numbering, grid squares in the outdoor area by coordinates.

The origin and development of KKS It is absolutely essential for the parties participating in the construction and operation of a power plant to agree upon a standard system for the designation and classification of the plant, its part and proceduer. Special guidelines apply to data characters G, F0 and A3. E — Binary and analog signal and variable conditioning Treatment system GUA Rainwater collection and drainage systems free for use e.

This code unit can be combined with any breakdown level as necessary for identification. Related Posts

Single line diagrams are the basic documents origins for a project related KKS coding in electrical engineering. For other engineering activities e. The original KKS number is still kept, even when another kind of equipment is used providing that the function according to the KKS equipment unit code is not changed e. If in a project hardware component is no longer used, it is not allowed to re-allocate its KKS number for another component in the same project. Numbering starts a new when one of the preceding code elements changes. Numbering may be consecutive or grouping. Numbering need not be continuous.

Procedure for Plant Identification(KKS Numbering System)

For this purpose, data character B1 can contain: Fictitious rooms in structures may be identified by numbering or coordinate systems. Filters in ventilation and air conditioning systems. Identification System for Combined Cycle Power Plant KKS coding Bearing in mind the scale of power plants being built up to the early sixties, the Plant Identification System AKS could be regarded as adequate for the needs of planning and construction engineers at that time. 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. Requirements to be met by the Identification System Mechanical Supports Supports may be identified using the system code or the structure code.
