C — Instrumentation and control systems Closed-Loop Control Circuits The principles for the identification of measuring circuits apply analogously to the identification of taggging control circuits on breakdown level 1. 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.
When creating in DCS systems secondary variables of the same technical installation that differs with counting taggibg for breakdown level 2, the same rules are to apply as for this variables created from the same installation.
Procedure for Plant Identification(KKS Numbering System)
Procedjre and Instrumentation Equipment Enter the email address you signed up with and we’ll email you a reset link. System numbering must consist of two digits. Details of application are subject to agreement between the parties to the project.
Room Identification by Numbering Serial no. Coding letters of the main groups F1 tafging specified on next and the subdivisions in F2 and F3 are given in the present chapter II. YB71 XB72 Control room; close, down For this purpose, data character B1 can contain: Fire protection sections are identified according to the room identification.
Identification System for Combined Cycle Power Plant (KKS coding)
Thus for example, it may be procedrue to use items which are identified differently on breakdown level 1 main system and associated parts of auxiliary and ancillary systems in order to fulfil a given process-related task functional group. System code System code consists of three letters and two digits. Due to the size kke power plants and the fact that the large number of parties participating are all in different locations, communication problems arise which can incur costs which cannot be estimated in advance.
Generally valid rules on the use of FN numbering are not expedient.
Installation Unit Code Serial no. Remember me on this computer. Main machine sets common to L.
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. A breakdown level 2 is used to identify the installation space.
Procsdure the following principles apply: M — Main machine sets A – Grid and distribution systems for electric power plants, thermoelectric power plants and heating plants Transducer Racks, Supports, Frames This auxiliary equipment is identified on breakdown level 1 using the code for the equipment location structure codewith the exception of auxiliaries for main machine sets and heavy machinery system code.
The individual breakdown levels are differently formatted.
This rule does not refer to direct measurement circuits, which apply to technical installation and physical variable. Skip to main content.
KKS Identification System for Power Plants – Function and Type
Physically separate rooms in structures are identified by numbering, grid squares in the outdoor area by coordinates. 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.
In case of single closed regulation circuits, it is divided into 2 parts: The next counting signs of the circuit does not change when is creating only one combined variable. 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. Point of Installation Identification Identification of points of installation of electrical and instrumentation equipment in installation units e.
The first digit is often used to point the kind sort of component designated in B1 B2. This code unit can be combined with any breakdown level as necessary for identification. A2 identifies control and instrumentation functions e.
Subsequent isolation and pressure equalization valves in the measuring circuit are components of the measuring circuit and therefore classified as KA. 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.
Further applications are subject to agreement between the parties to the project. AN atgging may be consecutive or grouping.
