Gojind The systems and equipments which are controlled or monitored by the local control equipment under supervision of the plant DCS shall also equip the KKS number. 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. Procedure for Plant Identification KKS Numbering System Control and instrumentation equipment which serves more than one main group may be identified under main group C for control and instrumentation, e. Room Code The room code serves to identify physically separate and fictitious rooms in structures and in the outdoor area. 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: The next counting signs of the circuit does not change when is creating only one combined variable. Redundant zeros must be written e.

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. Numbering conventions, once established, may not be altered, not even in the event of changes made in the progress of planning.
Redundant zeros must be written. An application-specific scheme of numbering may be established. However, such schemes may not have the effect of reserving numbers in other applications, not even within the same engineering discipline. Management systems e. If necessary, subdivisions of number ranges in Fn and An according to the division of work could be made. They have to be written down directly in the Function key code and must be respected by the partners.
Numbers are increased in media or process flow direction. The counting is related to any geographical direction. Main cooling water pump motor In two lines.
Procedure for Plant Identification(KKS Numbering System)
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.

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.
