4. EQUIPMENT TYPE AND NUMBER

4.1 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 contents are in accordance with “KKS identification systems for Power Stations” issued by VGB Kraftwerkstechnik GmbH Essen. (refer to attachment #5)

4.2 Requirements to be met by the KKS identification system



DOC NO.: WD010-MZ731-00004


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

• All installations and sub-systems have to be included,

• An adequate number of reserve codes must be available for future developments in power plant engineering,

• The classification of installations and sub-systems must be generally applicable to all types of power plant; all individual circuits and arrangements must, however, be clearly identifiable,

• Clear identification of all sub-systems,

• An identification used in a power plant must be non-recurring,

• Sub-division with graded details and a fixed in relevance to the data characters,

• Variable identification length depending upon the detailed requirements of the various areas of application,

• Independent identification of various systems must be possible,

• Ease of recognition ensured by clarity and an acceptable length for the identification,

• Plausibility check facility, especially for data processing,

4.3 Structure and application of the identification system KKS

KKS shall be applied for the process-related identification which identifies installations and equipment according to their assigned task in the power plant process.

A uniform identification structure was created with a maximum of four breakdown levels, except application to spare parts. And the Project shall utilize upto three breakdown levels with a maximum; the units referred to becoming smaller from left to right.

Table 1 summarizes the identification and type of data characters of the breakdown levels appearing in the KKS.

In the process-related identification the entire system is subdivided according to the function or process, since, whether for mechanical, electrical, control of civil



DOC NO.: WD010-MZ731-00004


engineering, the equipment units and components must be identifiable in relation to the process.

The process-related identification is for many applications the most important identification, since it permits, for example, locations of electrical and control equipment, rooms, signals, and the identification in circuit diagrams related to particular functions.

In the electrical and instrumentation control engineering sectors, the equipment for auxiliary services, power supply, open-loop-control, instrumentation, etc,. is treated as a process engineering function. The same applies to structures in civil engineering work.

The process-related identification corresponds to the identification block “Plant” in DIN 40719, part2. This block has the prefix sign “=”. According to the standard, the prefix sign can be omitted provided that the identification remains unambiguous.

4.7 Project related rules, agreements and procedures

• General rules on process-related identification

Piping & Instrument Diagrams (P&ID) are the basic documents (origins) for a Project related KKS coding.

Single line diagrams are the basic documents (origins) for a Project related KKS coding in electrical engineering. However, KKS codes for electrical consumers, measuring loops and items of I&C represented in Function Diagrams are originated in P & IDs.

For other engineering activities (e.g. layout planning, component engineering), KKS code must always be taken from the above mentioned basic documents.

In basic KKS documents (P&IDs and single line diagrams) the breakdown level 3 (component code) is never used.

Note: Special rules on point of installation identification and location identification have to be established within the relevant engineering disciplines (electrical, I&C and civil engineering). The basis are the KKS-Application Commentaries, Part B2, B3, and B4 by VGB.

• Rules on modifications and cancellations of KKS numbers. It is not allowed to change allocated KKS numbers for a Project, if these numbers have been released for the Project.

The original KKS number is still kept, even when another kind of equipment is used providing that the function according to the KKS equipment unit code is not changed (e.g. substitution of a gate valve by a globe valve).

If in a Project a hardware component is no longer used, it is not allowed to re-allocate its KKS number for another component in the same Project.

• Agreement on breakdown level “0” and the prefix number “F0”.

• General rules on other numbering code elements (FN, AN, BN).

Total Plant System Code prefix No.

“G” “F0” Contents

AES Comments is required



DOC NO.: WD010-MZ731-00004


Numbering starts anew when one of the preceding code elements changes.

Numbering may be consecutive or grouping.

Numbering need not be continuous.

Numbering conventions, once established, may not be altered, not even in the event of changes made in the progress of planning.

Redundant zeros must be written.

An application-specific scheme of numbering may be established. However, such schemes may not have the effect of reserving numbers in other applications, not even within the same engineering discipline.

Management systems (e.g. computer checking programs, allocation sheets) have to assure, that no double KKS numbers occur in the Project.

If necessary, subdivisions of number ranges in Fn and An according to the division of work could be made. They have to be written down directly in the Function key code and must be respected by the Members.

• General rules regarding direction of numbering

Standard designations have priority in all cases.

Numbers are increased in media or process flow direction.

Project counting directives refereed to local layouts are related to breakdown level “0”, and prefix number for system code “F1” and structures (F1=U) only.

The counting is not related to any geographical direction (e.g. not from west to east, not from north to south).

• Writing modus of KKS code Following structures of the KKS code are allowed:

- in one line with space between Function Level, Equipment Unit Level (and Component Level).

e.g. 19PAB10 AP001 (-M01)

- in two (three) lines
