KKS identification system for all types of power plants

with the expection of nuclear power systems.

It is not intended and it is not suitable as an instruction manual

1. 1 Purpose and Area of

Application

The power plant identification· system is applied to clearly identify plants, systems, parts and components to their purpose, type and location.

The content is in accordance with "KKS Identification Systems for Power Stations " issued by VGB PowerTech Service GmbH Essen, Germany.

1.2 Requirements

0

In order to perform the set tasks the identification system must be capable of satisfying the following requirements:

Uniform identification for all types of power stations and any connected processes

Sufficient capacity and detail for identification of all systems, components and structures

Sufficient capacity for extension to accommodate new technologies

Consistent identification for planning, licensing,

Non-language-based coding to ensure international usability

Application in computer data processing.

1 .3 Structure and Application The KKS consists of three types of identification: The process-related code

identifies installations and eguipment according to their assigned task in the power plant process

The point of installation code identifies the points of installation within an installation unit (e.g. cubicles, consoles, panels)

- The location code identifies the rooms and floors, or other installation sites for installations and eguipment in building structures. A uniform identification structure, with a maximum of four breakdown levels, was created for all three types; the units referred to becoming smaller from left to right.

summarizes the identification and type of data characters of the break-down levels for all three different types of identification appearing in the KKS.

1.3.2 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 or civil engineering, the eguipment units and compo-nents must be identifiable in relation to the process. The process-related identifica-tion is for many applicaidentifica-tions the most important identification, since it permits, for example, identification of electrical and control eguipment, signals, and the identification in circuit

1.3.3 Point of Installation Identification

As with the process-related identification, the KKS is also used to identify locations, principally of electrical and I&C equipment, but also of mechanical equipment. Locations - for example, coordinates, racks and positions in cubicles etc. -are identified in the break-down level

EQUIPMENT

UNIT.

The identification letters now used for the point of installation identification in the breakdown level

FUNCTION

may be the same as those for the

process-related identification. This improves recognition of the identification in the overall system. In order to prevent possible confusion between process-related identification and point of installation identification the prefix sign "+"must be added to the point of installation code (according to DIN

40719,

part 2). Resp. the breakdown symbol "full stop" between breakdown Level

1

and 2 must be used_ This prefix sign may be omitted only when there is absolutely no ambiguity- e.g. in layout documents.

diagrams related to particular functions.

In the electrical and instru-mentation & control (I&C) engineering sectors, the eguipment for auxiliary services, power supply, open-loop-control, instrumentation, protection, etc., is treated as a process engineering function. The same applies to structures

in civil engineering work_

The process-related identifi ca-tion corresponds to the identification block "Plant" in DIN

40719

,

part

2.

This block has the prefix sign

"=".

According to the standard, the prefix sign can be omitted provided that the identification remains unambiguous.
