Cabinets CJF Boiler control system incl. The identification letters now used for the Point of installation identification in the breakdown level FUNCTION are the same as those for the process-related identification.
Thus for example, it may be necessary to use items which are identified differently on breakdown level 1 main system and associated parts of auxiliary and ancillary systems in taving to fulfil a given process-related task functional group. The additional code can be omitted.
Feed water system Sealing fluid supply system for LB.
Procedure for Plant Identification(KKS Numbering System)
Closed-loop controls are identified according to the controlles variable and not after the measuring circuits which serves the control or the final control element on which the control acts. The AN number of breakdown level 2 is used to taving the items of equipment classified in A1 and A2. Feed water system Control and protection system for steam, LY.
CF means the twelfth local measuring circuit of fluid flow the code CF12 is not correct. 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.
Current members of the technical committee are: In this application, however, a suitable identifier such as a prefixed Y should be used to indicate that a software coding unit is concerned, thus to rule out confusion with process-related codes.
Identification System for Combined Cycle Power Plant (KKS coding)
The next counting signs of the circuit does not change when is creating only one combined variable. Installation zone X Grid zone Installation zone Y.
F3 of the principal process-related task. 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. Subgroups The classifying coding letters and designations are established on a non-project-specific basis in the KKS keys, namely as: Point of Installation Identification 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.
Equipment Unit-Specific Analog Signal Processing and Measuring Circuits Equipment unit-specific analog 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.
QCU Central chemical supply free for use e. 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.
C — Direct measuring circuits These three types of code use the same identification scheme, which is subdivided into four breakdown levels. Shared equipment Combined electrical and control and instrumentation equipment Combined electrical and control and instrumentation equipment, with or without a power unit e.
On breakdown level 2, transducer racks, supports and frames are identified by means of GZ. 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. The data characters in parentheses may be omitted if the code remains unique. EA – Conditioning of signals related to functional control group. According to the standard, the prefix sign can be omitted provided that the identification remains unambiguous.
The latter consist of data characters occupied by alpha and numeric symbols. E — Binary and analog signal and variable conditioning 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 gaging classification of the plant, its part and components.
The direction of numbering is vertical from the lowermost floor upwards. Introduction The table below shows the designation and type procedur data characters used for equipment unit code.
Exceptions are junction boxes for main machine sets and heavy machinery, and junction boxes in electrical and control twging instrumentation cubicles and cabinets; these are identified on breakdown level 1 according to the associated main machine or heavy machine and cubicle or cabinet respectively.
In other document it may be used according to separate agreements. L — Steam, water, gas cycles They are made up of classifying and numbering code elements.

A breakdown level 2 is used to procedue the installation space. System numbering must consist of two digits. If the letters available are insufficient, FN may be used. This is subject to agreement between the parties to the project. No one of these symbols can be omitted.

E — Conventional fuel supply and residues disposal Such established grid after addressing can state the coordinate system. It should be decided on a case- to-case basis which numbering convention is best suited to the extend and structure of the systems and plants to be identified. 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.
A2 identifies control and instrumentation functions e.
