The KKS system is a classification system for the complete power plant and its components and provides a common language for the designer. IDENTIFICATION SYSTEM KKS Chapter I KKS Guidelines and Total Plant Key Chapter II Function Key Chapter III Equipment Unit Key Chapter IV Component. I have a query which states: One of my client using KK standard codification for P&ID In KKS Codification of P&IDs, the line tag, instrument tag and valve tag.

Coding letters and designations of main groups B1 for components as given in corification Component Key and for signals and signal applications: H — Conventional heat generation All signals in such automatic regulation system in breakdown level KKS 0, 1, 2, are described identically.
KK standard codification
On breakdown level 2, transducer racks, supports and frames are identified by means of GZ. Installation Unit Code Serial no. A2 identifies control and instrumentation functions e.
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. The second character of FN numbers the cubicles. 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.
Installation zone X Grid zone Installation zone Y. Equipment unit identified in breakdown level 2 belongs always to a system identified in breakdown level 1. X — Heavy machinery not main machine sets Point of Installation Identification The individual breakdown levels are differently formatted.
Identification System for Combined Cycle Power Plant (KKS coding)
The codkfication characters in parentheses may be omitted if the code remains unique. In such instances the first character of FN has a classifying purpose.
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. In case of single closed regulation circuits, it is divided into 2 parts: Redundant zeros must be written e. AL According to cubicles, divisions, sections etc. Measuring circuits are identified according to the system within the interfaces of which the sensor is installed. Help Center Find new research papers in: X Signal codificatiin Y Signal applications Z Gated signals No generally valid rules kka been made for signal and application areas.
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. AN numbering may be consecutive or grouping. 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.
It should be decided on a case- to-case basis which numbering convention is best suited to the extend and structure of codofication systems and plants to be identified. Requirements to be met by the Identification System To perform the set tasks the Identification system must be capable of satisfying the following requirements: Log In Sign Up.
E — Conventional fuel supply and residues disposal The AN number of breakdown level 2 is used to number the items of equipment classified in A1 and A2. There are also cases of deviations consisting in using the dividing symbol twice, and AN, e. The outdoor area is designated in the breakdown level 1 by symbols: Structure Code Serial no. However the following principles apply: Process-Related Identification Process-related identification of systems and items of equipment according to their function in mechanical, civil, electrical and control and instrumentation engineering.
A breakdown level 2 is used to identify the installation space.
Special structures, ducting structures are designated in main group F1 with coding letter U and in subgroup F3 with following coding letters:
