KKS - INTRODUCTION (IDENTIFICATION SYSTEM FOR POWER PLANTS)

1.1

Purpose The power plant identification system is applied to clearly identify plants, systems, parts and components to their purpose, type and location. The contents are based on the “Identification Systems for Power Plant (KKS)” published by VGB - Technical Association of Large Power Plant Operators.

1.2

Requirements to be met by the identification system KKS In order to perform the set tasks the identification system must be capable of satisfying the following requirements: 

Determination of all installations and sub-systems,



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,



Subdivision with graded details and a fixed meaning for the data characters,



Variable identification length depending upon the detail 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,



Existing standards, guidelines and recommendations must be taken into account.

Structure and application of the power plant identification system KKS The KKS consists of three types of identification: 

The process-related identification identifies installations and equipment according to their assigned task in the power plant process,



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



The location identification identifies the rooms and floors, or other installation sites, for installations and equipment 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. Fig. 1 shows the breakdown levels, referring to a process-related identification as an example. Serial Number of Breakdown level Name of Breakdown level Example

1.3.1

Rev.F

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 of civil 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, part 2.

This block has the prefix sign “=”.

According to the standard, the prefix

sign can be omitted provided that the identification remains unambiguous. 1.3.2

Point of installation identification As with the Process-related Identification, the KKS is also used to identify locations, principally of electrical and instrumentation and control equipment, but also of mechanical equipment. Locations, for example, coordinates, racks and positions in cubicles etc. are identified in the breakdown level EQUIPMENT UNIT. 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. 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).

The breakdown symbol “full stop” between breakdown

Level 1 and 2 must be added. This prefix sign is omitted when there is absolutely no ambiguity in layout documents. 1.3.3

Location identification In order to clearly identify the position of plant, subsystems and equipment in the power plant, the building structure and floor is entered at the breakdown level FUNCTION, and the rooms on the various floors of the building structure at the breakdown level EQUIPMENT UNIT. The breakdown level COMPONENT is omitted in such cases. Fire protection sections are identified according to the room identification. 3

Point of Installation Identification This designation is used for the point of installation identification in assembly units for instrumentation and control system (for e.g. in cubicles, panels, consoles etc.) Not only is this designation important for cabling but for the interconnection of electrical equipment and equipment of the control technical as well. The Point of Installation Code is divided into different breakdown levels with different meanings, from right to left in diminishing order, starting from the Total Plant up to the Installation Space Code. The following example illustrates the structure of the Point of Installation Code:

1.9.2.2 Level 2 The alphabetical designation of installation point in the vertical direction (rows designation) is done by data character A1A2. Data characters AN indicate counting in the horizontal direction (columns numbering). As alphabetical letters (without I and O) are used, on data characters A1 A2 for point of installation identification in the assembly unit there occurs the combination of letters as for the aggregate designation according to process. In order to discriminate it from other types of designation there must be written “.” (period) in front of the breakdown level 2. As a result to a fact that there are often used codes next to each other in the electric therefore there is used “=” (sign of equality) in front of designation code according to process and “+” (sign of plus) in front of designation code according to point of installation, which in similar cases neither have to contain level 2 nor period for the discrimination of prefix code, which can fall off in case that the specification stays unambiguous. The following principles direct for the designation of installation point in assembly units: - The counting direction and counting sequence derive from the initial position data(left top corner) at the view to the front side. - The counting direction at the view to the front side is from left to right and from top to bottom. - The vertical breakdown is axis Y (i.e. rows designation) is designated with Capital letters. - Horizontal breakdown in axis X (i.e. columns numbering) is designated with Arabic numbers. 1.9.3

PROJECT RELATED RULES, AGREEMENTS AND PROCEDURES

2.1

General rules on process-related identification 

Rev.F

Piping & Instrument Diagrams (P&ID) and Single Line Diagrams (SLD) 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.



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 SLD), the breakdown level 3 (Component code) shall not be applied.



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 is the KKS - Application Commentaries, Part B2, B3, and B4

by VGB. 2.2

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

16


2.3

Rev.F

General rules on other numbering code elements (Fn, An, Bn). 

Numbering starts a new 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 partners.

2.4

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



The counting is related to any geographical direction. e.g. from North to South, from West to East (in case of electric room, from Left to Right viewed from cubicle front) and from Lower part to Upper part.

2.5

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

Rev.F

In one line with space between Function Level, Equipment Unit Level (and Component Level). e.g. 13PAC10AP001(-M01) (eg. Main cooling water pump (motor))



In two lines e.g. 13PAC10 AP001(-M01)

2.6

Exception 

All the systems and equipments within boiler supplier scope which are controlled or monitored by the plant DCS shall equip the KKS number. The systems and equipments which are controlled or monitored by the local control equipment under supervision of the plant DCS shall also equip the KKS number.



Very minor pipes, such as pipes for instrument indicated in P&ID within boiler area shall not equip the KKS number.



Parts and components of civil work, such as structure, floor and beam etc shall not equip the KKS number.



The numbering system for control panel cables shall not equip the KKS number.



Point of installation identification and location identification are not applicable to boiler supplier scope.
