F Point of Installation Identification This designation is used for the point of installation identification in assembly units for instrumentation and control system for e.
Feed water system Control and protection system for steam, LY. Rules on the Keys Format of Breakdown Levels Order according to voltage levels, counted from higher voltages to lower. Coding letters and designations of the main groups A1 as given in the Equipment Unit Key: X — Heavy machinery not main machine sets Mechanical Supports Supports may be identified using the system code or the structure code.
Coding letters and designations of main groups B1 for components as given in the Component Key and for signals and signal applications: When technical installations differs only with counting signs of installation it is necessary to assign to a secondary variable counting signs like for one of those installations e. This applies analogously to supply systems. 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.
However the following principles apply: Steam system common to LA. It is a common practice to apply a grouping numbering of equipment units: Process-Related Identification Process-related identification of systems and items of tagving according to their function in mechanical, civil, electrical and control and instrumentation engineering. Fictitious rooms in structures may be procsdure by numbering or coordinate systems.
Equipment unit classification Serial no. They have to be written down directly in the Function key code and must be respected by the partners.
Special guidelines apply to data characters G, F0 and A3. No one of these symbols can be omitted. Steam, water, gas cycles Q.
F Equipment Unit Key, groups A1: Remember me Forgot password? The Equipment Unit identified in breakdown level 2 belongs always to the System designated in breakdown level 1.
Procedure for Plant Identification(KKS Numbering System)
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.
System One should remember, that the code of a system must consist of five symbols: The breakdown levels have the following structures: EZ Taging For example: Supply systems which serve only one equipment unit are identified on an equal footing as subsystems of the system in which they are installed. Subgroups The classifying coding letters and designations are established on a non-project-specific basis in the KKS keys, namely as: They are made up of classifying and numbering code elements.
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. 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.
Such established grid after addressing can state the coordinate system. F process system e.
Installation Space Code Serial no. S — Ancillary systems The allowable notations are fixed. Measuring Circuits Measuring circuits comprise analog signal acquisition, conditioning, distribution and measured data recording and indicating processing elements. 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 procerure mechanical engineering, process engineering, civil engineering, and electrical and control engineering procedurr.
C — Instrumentation and control systems The individual breakdown levels are differently formatted. Fire protection sections are identified according to the room identification. 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: EA – Conditioning of signals related to functional control group.
On breakdown level 2, the individual windings are classified but not on a phase-specific basis by means of GT for transformer equipment and numbered starting on pprocedure high-voltage side. Tagying Code Serial no.
Identification System for Combined Cycle Power Plant (KKS coding)
F General rules on other numbering code elements Fn, An, Bn. Gated analog signals representing physically similar direct measured variables are identified by means of a set number, e. If consumer system limits are not defined, the beginning of consumer system is at branch-off or outlet of supply system or at a point where unequivocal allocation of a component to consumer system is possible.
If this is not the case, all floor numbering codes of the total plant must be written uniformly with three data characters in AN. In the electrical and instrumentation control kis sectors, the equipment for auxiliary services, power supply, open-loop-control, instrumentation, etc.
