Establishments for Combined-Cycle Power
Power Generation
Plants (GUD®)
As the Guidelines for KKS Application do not contain all the rules necessary for each individual project,
these establishments provide clear instructions as to how the KKS system should be applied to
combined-cycle power plants (GUD®).
These establishments refer to the Guidelines for KKS Application (Edition 1994), compendium of ”Estab-
lishments between the Parties to the Project” to be made on a project-specific basis, page 36 and 37.
According to the scope of supply of the Identification System for Power Plants KKS, these establish-
ments are divided into:
• General establishments
• Establishments for the allocation on process-related codes
• Establishments for the allocation of “point of installation“ identifiers
• Establishments for the allocation of location identifiers
General establishments
2. Rules governing numbering systems and direction of numbering for all numbering code
elements
The principles established in the Guidelines for KKS Application apply. An application-specific logic
will be established for the specific engineering disciplines.
In all other cases the code may be written with or without spacing but in such a way that it cannot be
misinterpreted.
5. Allocation of unreserved classifying code elements which are freely available for
use (F1, F2, F3)
Non-listed code elements (F1 - F3) may only be used by agreement with the Power Generation KKS
Liaison Officers and have to be included in the project-specific establishments for KKS application.
All code elements (F1, F2, F3) must always be written.

Designation of data character F0 F1 F2 F3 FN
Permitted entry NN AAA NN
Combined-cycle power plants (GUD®) are generally constructed from modules which are combined to
form process units, and ultimately the combined-cycle power plant (GUD®) itself.
The prefix number should be allocated in accordance with the requirements of optimum computer-aided project
processing (based on modules and/or process units), such that a repeatedly recurring system or facility need be
encoded only once; it may later be duplicated by provision of the prefix number.
The two prefix numbers are depending on the overall plant configuration (e.g. multi unit plants). It has to be
documented in the 'Project-specific establishments according to the Guidelines for KKS Application', if
any other prefix numbers than the standard prefix numbers above are used.

Only for valves with KKS function key (F1) = Main Machine sets (*M*) and Heavy Machinery (*X*)
As shown in the matrix, specific functional statements for valves (AA…), pipes (BR…) and measuring
circuits (C….) are encoded in the first of the three AN data character fields.
The numbering in the 2nd and 3rd data character fields starts again from zero once one of the previous
identifier components changes. In process systems or facilities, numbering should proceed in as-
cending order in the direction of medium/material flow.
Reserve numbering capacity should be provided for, particularly in the case of valves and direct
measuring equipment, so that numbering can still proceed in ascending order in the direction of me-
dium flow even where plans are changed, backfitting is performed, etc. Leading zeros must be in-
cluded in the entries.

11. Rules governing entries in the BN data character field for component numbering
The rules laid down in the Guidelines for KKS Application, Section 3.1.3 shall apply with the exception
of the general rules relating to the numbering system. Examples of BN numbering can be found in the
General Application Commentaries, Part A, Section 3.1.3.2, and in the Engineering Discipline Specific
Application Commentaries, Part B1, Section 3.3.2.
12. Rules governing the identification of supports in the field of mechanical engineering
As a rule, supports within a mechanical engineering context should be encoded on the basis of an en-
try in breakdown level 1 which represents a plant section ( = building section). The relevant classifica-
tion key attribute to be entered in the A1A2 data character field is "BQ" ( = support).
Identifier mask for supports in the field of mechanical engineering:
Breakdown level 1 2
Designation of data character F0 F1 F2 F3 FN A1 A2 AN A3
Permitted entry NN UAA NN BQ NNN N
13. Rules governing the identification of mechanical (process) systems which supply the main
process
The rules laid down in the Guidelines for KKS Application, Section 5.4.3, shall apply for the encoding of mechani-
cal supply systems. Examples can be found in the Engineering Discipline Specific Application Commentaries,
Part B1, Section 3.1.1.3.
15. Rules governing the classification and numbering of signals and signal applications in break-
down level 3
Signals are entered in the B1 data character field as "X", and signal applications as "Y".
The classification key used in combined-cycle power plant (GUD®) systems for the structure of signal
identifiers and signal application identifiers, and also the regulations explaining the use of the BN data
character fields in the structure of the classification key, are stipulated in a separate procedure.

18. Rules governing entries in the FN data character fields for the numbering of installation units
in breakdown level 1
An "installation unit" is the result of the topographic view onto electrical and I&C systems/sub-systems
denoted by the prefix "=". The fact that it is an identifier based on a topographical view is indicated by
the entry following the prefix "+" being identical to the entry following the prefix "=".
For related information and general rules, see Section 8 above.
· The FN numbering code after the F1F2F3 facility key advances consecutively. The delineated overall plant is
generally entered as "00" (double zero).
· Viewed from the front (e.g. operating side), the direction of numbering and the numbering sequence for facility
sections/subsystems (control desks, panels, bays, cabinets) within the overall plant proceeds from left to right.
19. Rules governing the further subdivision of installation units according to installation spaces
The various installation spaces are identified in breakdown level 2 using the installation unit identifi-
ers.
The entries in breakdown level 2 depend on the types and the manufacturers of installation units used
in the project.
21. Use of the two F0 data character fields in the identification system
(See Section 7 above. A prefix number is entered here before the F1F2F3 building/structure key.)

23. Rules governing entries in the FN numbering data character fields for installation area
identifiers
An "installation area" is the result of the topographical view onto electrical and I&C systems/sub-
systems denoted by the prefix "=". The fact that it is an identifier based on a topographical view is in-
dicated by the entry following the prefix "+" being identical to the entry following the prefix "=".
As buildings/structures are generally subdivided into separate floors, attention should be paid to the
following points:
All main floors and all main service platforms are provided with a floor number following the F1F2F3
building/structure key, i. e. identifiers for building/structure floors are assigned in breakdown level 1.
Individual "floors" or "platforms" with small height differentials are not provided with separate identifi-
ers; they are merged as a "main" floor. The direction of numbering in an overall building/structure pro-
ceeds vertically from bottom to top. Numbering is consecutive, beginning with 01 for the bottom floor
in an overall building/structure.
24. Rules governing the further subdivision of an installation area into installation locations
(rooms)
The established identification of rooms by numbering shall be applied.
Different rooms are identified and delineated by an entry in breakdown level 2 which is based on the
identifier for an area (floor) in breakdown level 1.
The room is identified in AN by 2 numerical data characters; leading zeros must be entered. The base
point for the numbering system is the point of intersection of the lowest values for the numerical and
alphabetical building structure axes. Rooms on each floor are numbered consecutively in ascending
numerical order starting from 01 at the base point, and then following the course of the main service
corridors.
25. Rules governing the identification of individual substructures combined to form one
structure
Not applicable for combined-cycle power plants (GUD®).
26. Rules governing the identification of duct and bridge structures serving as connecting
structures
Bridge and duct structures which provide a connection between two other buildings/structures are as-
signed a structure group identifier in F1F2. In F3 the identifiers Y (for bridge structure) or Z (for duct
structure) are entered.
Example:
UHY Bridge structure between *UHA* and *UMB/UMA*
UGY Bridge structure between *UGD* and *UMB*
