KKS CODIFICATION PDF

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.

Data character G codjfication well as data character F0 can be omitted in KKS if the further part of designation will remain complete univocal. H — Subassemblies of main and heavy machinery Introduction The table below shows the designation and type of data characters used for equipment unit code.

Special Rules for Mechanical Engineering I – 5. If the letters available are insufficient, FN may be used.

X and Y zones are outside the grid. 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.

If necessary, further grouping can be performed by using FN. Such established grid after addressing can state the coordinate system.

KK standard codification

A2 identifies control and instrumentation functions e. Kraftwerk – Kennzeichen – System KKS was published in 1st edition by the VGB and is codirication the basis for the designation of installations and subsystems in power plants. D — Loop control circuits YB71 XB72 Control room; close, down Safety equipment, consisting of safety valves and their associated piping, are assigned to the system to which they are connected.

In case for eg. In the meantime, the AKS has been adopted as the main system of identification in a number of conventional and nuclear plants. P — Cooling water systems The Equipment Unit identified in breakdown level 2 belongs always to the System designated in breakdown level 1. EZ Protection For example: Notation of Codes The code may be written with or without spacing but in such a way that it cannot be misinterpreted.

For example maximum of a codificwtion direct measured variables: Generally valid rules on the use of FN numbering are not expedient. Deviations with respect to the type of data character A or N and their quantity are allowed by DIN Part 2 and are subject to agreement between the parties to the project. Skip to main content.

Identification System for Combined Cycle Power Plant (KKS coding)

M — Main machine sets The second character of FN numbers the cubicles. Equipment unit identified in breakdown level 2 belongs always to a system identified in breakdown level 1. It is a common practice to apply a grouping numbering of equipment units: Steam system common to LA.

If several process-related systems are situated in one structure we designate this structure according to the main, most important system.

FN numbering is governed by the following principles: Special Rules for Mechanical Engineering Numbering starts anew when one of the preceding code elements changes. All signals in such automatic regulation system in breakdown level KKS 0, 1, 2, are described identically. 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.

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.

Read from left to right no data characters may be omitted.

Signals and Signal Applications Breakdown level 3 is used to identify signals and their applications. Subgroups The classifying coding letters and designations are established on a non-project-specific basis in the KKS keys, namely as: Calculation of new value on base of 2 variables, e.

Point of Installation Identification Identification of points of installation of electrical and instrumentation equipment in installation units e.
