KKS
Identification System for Power Stations
This booklet serves as an information tool about the
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
for KKS codification.
For this purpose, please refer to project-specific

1.3. 1 Identification a~.:~d Type
of Data Characters
Table 1 summarizes the
identification and type of
data characters of the breakdown levels for all three
different types of identification
appearing in the KKS.
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 location code identifies
the rooms and floors, or
other installation sites for
installations and eguipment
in building structures.

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 breakdown level EQUIPMENT
The process-related identification corresponds to the
identification block "Pla nt" 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 remai ns
unambiguous.
The process-related identification is for many applications
the most important identification,
since it permits, for example,
identification of electrical and
control eguipment, signals,
and the identification in circuit
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.
A
N
()
In the electrical and instrumentation & control (I&C)
engi neering sectors, the
eg uipment for auxiliary
services, power supply, openloop-control, instrumentation,
protection, etc., is treated as
a process engineering function.
The same applies to structures
in civil engineering work_
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 components must be identifiable in
relation to the process.
The point of installation
code identifies the points
of installation within an
installation unit (e.g. cubicles,
consoles, panels)
-
diagrams re lated to particular
functions.
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.

1.3.4 Location Identification
In order to clearly identify the
position of plants, sub-systems
and equipment in the power
station, the code of building
structure and floor is entered
at the breakdown level

on the various floors of the
building structure at the

consecutive or grouping.
- Numbering need not be
continuous.
It may be necessary to identify
units, non-unit specific plants
or extension stages w ihin a
power station, such that a
clear and unambiguous distinction exists between them.
This is provided by breakdown
level 0 - Overall plant. This
identification must be agreed
upon by all parties concerned,
regarding the contents and
and typre of data character
{A or N). Especially the identification of existing units has
to be taken into account.
The breakdown level "Overall
plant" can be omitted when
the designation remains
unambiguous.
If in the overall plant two or
more identical plants or systerns are to be identified {e.g.
2 boiler plants, 2 gas turbines
with attached el. generators
and HRSGs, 2 structures with
equal purpose) the prefix
number F0 is used to distinguish between them. Each F0
number is valid only in the
area of the Function concerned.
O n no accounts it to be
considered for the counting
of system sections as parallel
lines, data characters FN
being used for this purpose.
- 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-speci fic
scheme of numbering may
be established . However, it
has to be valid throughout
all project disciplines in
order of an unequivocal
understand ing of the code.
- Management systems {e.g.
computer checking programs,
allocation sheets) have to
assure, that no double
KKS numbers occur in the
project and that no multiple
KKS numbers are assigned
to one item.
- If necessary, subdivisio ns
of number ranges in FN
according to the division of
work could be made. They
have to be written down
directly in the project-related
Function key and must
be respected by the partners
involved.
General Rules on

Elements (FN, AN, BN)
- Numbering starts anew
w hen one of the preceding
code elements changes.
- Numbering may be

a project, if these numbers
have been released for
the project.
-The original KKS number is
still kept, even w hen another

originated in P&IDs.
- For other eng ineering
