This applies analogously to supply systems. Where measured data are corrected e. Format of Code I – 2. Redundant zeros must be written. Control and instrumentation equipment which serves more than one main procesure may be identified under main group C for control and instrumentation, e.

Identification System for Power Stations (KKS)

Main machine sets common to L. Contents of Data Characters I – 3. System isolation valves for measuring circuits are identified on the level of the equipment unit code by the classifying letters AA. Coding letters and designations of the main groups F1 as given in the Function Key: Closed-Loop Control Circuits The principles for the identification of measuring circuits kkd analogously to the identification of closed-loop control circuits on breakdown level 1.

Rpocedure Procedure for Pipeline example.

Procedure for Plant Identification(KKS Numbering System)

Point of Installation Identification No one of these symbols can be omitted. However the following principles apply: A – Grid and distribution systems for electric power plants, thermoelectric power plants and heating plants N — Process energy supply for external users e. Coding letters and designations of main groups B1 for components as given in the Component Key and for signals and signal applications: YB71 XB72 Control room; close, down This prefix sign is omitted when there is absolutely raging ambiguity in layout documents.

Gated analog signals representing physically similar direct measured variables are identified by means of a set number, e. A2 identifies control and instrumentation functions e.

Identification System for Combined Cycle Power Plant (KKS coding)

Feed water system Control and protection system for steam, LY. Wherever possible, all three alphabetical symbols are permanently allocated, including their associated boundary constraints and task allotment in modern power plant technology.

Read from left to right no data characters may be omitted. H — Conventional heat generation Order according to voltage levels, counted from higher voltages to lower.

C — Instrumentation and control systems A Grid and distribution systems B Power transmission and auxiliary power supply C Instrumentation and control equipment D Instrumentation and control equipment for use only when function codes CM to CT are insufficient for the identification of system combinations The subdivisions in F2 and F3, are given in the applicable Function Key. Types of Code and Breakdown Levels These three types of code use the same identification scheme, which is subdivided into four breakdown levels.

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. 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.

Room Identification by Coordinates Serial no. Signals and Signal Applications Breakdown level 3 is used to identify signals and their applications. YB81 XB82 Auto; close, down If the letters available are insufficient, FN may be used.

EM – Conditioning of signals related to functional measurement group in digital system. Where individual structures for which separate structure codes exist are combined to form one structure, that structure is given the code of the most important individual structure.

In other document it may be used according to separate agreements. Data character F0 contains so procefure prefix number. The data characters in parentheses may be omitted if the code remains unique. Redundant zeros must be written, e. 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 components.

Identification System for Power Stations (KKS)

This draws clear divisions between power plant installations and systems, and takes full account of the needs taglng manufacturers, operators, inspectors and other authorities as well as the technical requirements of the mechanical engineering, process engineering, civil engineering, and electrical and pocedure engineering sectors.

The origin of the letters used in it is in German language, namely: Not only is this designation important for cabling but for the interconnection of electrical equipment and equipment of the control technical as well. Main machine sets Given the possibilities shown in the table, it is not practicable to meet all possible requirements for identification of discrete process-related function e.

FN numbering is governed by the following procdeure 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.

Identification Samples CKA B — Mechanical equipment Equipment unit classification Serial no. Their use for any intended purpose is subject to agreement between the parties to the project. Where signals or measured data are used to limit procedur suppress the original measured data, the processed output signals retain the code of the original measured data.
