1 INTRODUCTION
1.1
KKS - SCOPE AND GUIDELINES
The Identification System for Power Stations "KKS" serves to identify plants, sections
of plants and items of equipment in any type of power station according to task, type
and location. It is to be used by all engineering disciplines for planning, licensing,
construction, operation and maintenance.
The KKS, or sections thereof, can be combined with other identification systems in
order to meet additional identification requirements.
The Application Commentaries are supplements to the KKS Guidelines and are
intended to give assistance in use of the identification system.
The diagram below shows the relationships between the KKS Rules and KKS
Application.
1.2
DESIGNATION AND TYPE OF DATA CHARACTERS
In consideration of the various requirements placed on the identification of plants,
section of plants and items of equipment in power stations, KKS has three different
types of code:
Process-related code
Process-related identification of systems and items of equipment according to their
functions in mechanical, civil, electrical and control and instrumentation ngineering.
The process-related designation is the most important designation. It is used in the
technical and civil engineering as well as in the electrical and control and
instrumentation engineering.
Point of installation code
This designation is used for the point of installation identification of electrical
components as switches, indicators etc. in assembly units (for e.g. in cubicles, panels,
consoles, etc.). This designation is necessary for the cabling and wiring of electrical
and control and instrumentation equipment. This designation is used only for electrical
and instrumentation and control system.
Location code
This designation is used for identification of location in structures, on floors and in
rooms and also of fire areas. These three types of designation use the same
identification scheme, which is subdivided into maximally four breakdown levels.
Originally the titles of the breakdown levels were based on process-related code:
At above mentioned three types are the breakdown levels as follows:
1.2.1
KKS-Process-Related Identification
A = Alphabetical symbols (Latin alphabet except I and O and special symbols) N = Numeral
symbols (Arabic numerals) - see Doc. No. 0AM/13-1
The data characters in parentheses ( ) may be omitted if the code remains unique.
1.2.2
Tag numbers Prefix
In generally according to ZENEN Contract for Tereshkovo, prefix is defined “RU01A”
Sequential numbers will be used as follows:
00 – for common system
01 – for unit 1 (GTG no.1, HRSG no.1, Flue Gas By-Pass no.1, etc..)
02 – for unit 2 (GTG no.2, HRSG no.2, Flue Gas By-Pass no.2, etc..)
03 – for unit 3 (GTG no.3, HRSG no.3, Flue Gas By-Pass no.3, etc..)
04 – for unit 4 (GTG no.4, HRSG no.4, Flue Gas By-Pass no.4, etc..)
05 – for unit 5 (GTG no.5, HRSG no.5, Flue Gas By-Pass no.5, etc..)
06 – for unit 6 (GTG no.6, HRSG no.6, Flue Gas By-Pass no.6, etc..)

4 DESIGNATION OF I & C CIRCUITS ACC. TO KKS
4.1
DESIGNATION METHOD OF CIRCUITS I & C
4.1.1
Symbols of I & C circuits specify:
The location of I & C circuit
The consumption place of information entry
The place of information about process course
4.2
DRAWING AND APPLICATION OF SYMBOLS IN THE DIAGRAMS
4.2.1
Symbols are drawn as graphical symbols by a solid light line and lighter then lines which
represent the mechanical equipment.
4.2.2
It is recommended to use the oval of such a dimension to be possible to write legibly the
entire alphabetical and numerical codes defining I & C circuit. Minimal letter height
(recommended) is 2,5 mm.
4.1
The first letter indicates the measured or controlled variable. A suitable letter from the column
”Letters”, corresponding ”Measured (controlled) quantity” of the table in the paragraph
1.4.4.2, is chosen. If needed, an additional letter from the column ”Additional character” can
be added.
4.2
Further letters will be chosen from the column ”Function of circuit” from above mentioned
table.
4.3
If in the lettered code besides the first letter character are also two or more other
characters, these characters shall be lined up in the order I R C T Q S Z A. (This condition
does not relate with additional letters, mentioned in the column ”Additional character. Letter
I may be omitted, if the indicator is provided with indication of measured variable.
4.2.3
It is recommended to use the united designation (for e.g. ovals) and dimensions of symbols
in whole documentation, while the basic position of symbols is always situated parallely with
the drawing border.
4.2.4
A stalk of symbol can also be broken, breaking must be (if possible) situated parallely with
the drawing border and it must end on the equipment outline in place for the signal
extraction.
4.2.5
For the local I & C circuit are drawn only so called empty symbols, i.e. without the halved line
drawn instead of the
4.2.6
longer axis of symbol:
For the remote I & C circuit is symbol drawn with the halved line, which is drawn instead of the
longer axis of symbol. Symbol, which is drawn this way, specifies also the place of
information, in this case it is central (main) control room;
4.2.7
Symbol is drawn with two parallely halved lines, which are drawn instead of the longer axis of
symbol for the remote circuit, but with the matter that the place finformation shall be in the
auxiliary (secondary) control oom.
4.2.8
Symbol for local and remote I & C circuit can be also mutually connected so that they are
either drawn next to each other or above each other and the outline of symbols is
interconnected by comma. Signal line is usually represented by dashed line (DIN) or
uninterrupted line, which is crossed out in regular intervals by oblique line and oblique lines
form an angle with line approx. 60°.

MEASURING CIRCUITS - KKS DESIGNATION ACC. TO PROCESS
4.3.1
Equipment classification
4.3.2
Alphabetical designation of measuring places (Breakdown level 2 - data characters A1A2)
4.1
Alphabetical designation acc. to data character A1
A
Mechanical equipment (machines incl. drives, accessories etc.)
B Mechanical equipment (incl. accessories)
C Direct measuring circuits
D Closed-loop control circuits
E Analog and binary signal conditioning
F Indirect measuring circuits
G Electrical equipment
H Subassemblies of main and heavy machinery
4.2
Alphabetical designation of measured quantities acc. to data character A2 responding to ISO
3511-1 (DIN 19227 part 1)
Important notice:
Letter Z can only be used when emergency activity is required, for example shut down,
switched-off (not operational but the emergency shut down) etc.
Letter S as a function is used in relation to switching for example pump switching-on
and switching-off from level etc.
Letters H and L designate limits of measured quantities. Letter H designates rising
value, letter L designates dropping value. Number of letter must relate to the required
number of limits without respect to the following activity to reach any limit.
Limits designation is L1, L2, L3, H1, H2, H3, etc.
For letters H directs, that H2 designates higher limit then H1. Letter H3 designates
higher limit then H2 etc. for letters L directs, that L2 designates lower limit then L1.
Letter L3 designates lower limit then L2 etc.
Letter L also designates position OFF and letter H designates position ON. (It directs for
manual, electrical and hydraulic drives or also for the mechanical parts).
Letter J designates the automatic cyclic scanning of measured quantity. It designates if
the measuring central office is equipped with system for the automatic cyclic scanning
values of measured quantities then the letter J is designated at particular items of
instrumentation.
In P&I diagrams the marks of position GI (0 - 100%), alike the marks of other
measuring circuits are drawn and that at valves, that are governed ”more-less” or at
control valves and flaps, which are controlled from physical variables (level, pressure,
temperature, etc.) and it is for a reason that the position indicator is wired with cables
by the supplier I&C. In the electrical load list also the position indication 0 - 100% is
mentioned at these consumers.

PIPING LINES IDENTIFICATION CODING
BREAKDOWN LEVEL 1
The subdivision of the elementary system (FN) is accomplished by taking numbers in the
direction of the flow. This subdivision may also be the limit of scope of supply between
partners. Gaps are left in the numbering.
BREAKDOWN LEVEL 2
- BR is the equipment code for all piping and ducts (codes A1 A2).
-
The line order number (NNN) is taken in the direction of the flow. For this number,
the following series of numbers are defined:
The 1st number N1 distinguish purpose of pipeline as follows:

SYSTEMS NUMBERING - BREAKDOWN LEVEL 1 - DATA CHARACTER FN
Numbering of the mechanical equipment which is described in details
0AM/13_1 uses the decade counting preferably.
The gradual numbering is used for the electrical equipment, where numbers
means for e.g. numbers of fields. The following principles direct for the
numbering on data character FN:
Numbering begins always again, when one of previous parts of reference
symbol is exchanged.
- Unimportant zeros must be recorded.
- Numbering can be provided with spaces.
- At numbering is important to stress out the possible extension done later
on for equipment such as (spare field, cabinets)
- Numbering is directed acc. to priorities (for e.g. main and auxiliary
equipment) or acc. to specific direction (from left to right, from top to
bottom).
-
The following numeral designation was agreed on a data character FN for
some systems of the electrical equipment (transformers, batteries,
converters):

aggregates A (pumps, fans, valves etc.), equipment B (tanks, gripping, etc.)
and measuring circuits C. These main groups A, B, C are used in the same
way in the mechanical and civil engineering as well as for the electric and
control engineering. Electrical equipment is classified in the main group G:

There are used numbers for the serial numbering of aggregates at the place of
aggregates for letter G - electric power plant equipment. Unimportant zeroes
must be mentioned.
The exception is formed by local control cabinets in the group GH (electrical,
instrumentation units identified by process system), there is used the numeral

KKS DESIGNATION ACC. TO 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.
This method of designation acc. to point of installation identification in assembly units
serves only for the instrumentation and control system.
Number of data characters is directed by required fineness of raster field division.
A = Alphabetical symbols (Latin alphabet except I and O and special symbols)
N = Numeral symbols (Arabic numerals)
The data characters in parentheses (..) may be omitted if the code remains unique.
Breakdown symbol "period" must be always written in order to discriminate this
sort of designation acc. to process and from designation acc. to point of installation
identification.
5.8.1
Breakdown level 0 and 1
There are the same principles in the breakdown level 0 and 1 as for the designation of
process mentioned in 1.3.1, 1.3.2, 1.3.3 a 1.3.4 therefore we do not mention it again.
5.8.2
Code of installation point - Breakdown level 2
The alphabetical designation of installation point in the vertical direction (rows
designation) is done by data characters A1A, data characters AN indicate counting in the
horizontal direction (columns numbering). Data character A3 can be used for designation of
special integrated equipment of design groups or design units, or further breakdown of AN
can be used.
As alphabetical letters (without I and O) are used, on data characters A1A2 for point of
installation identification in the assembly unit there occurs the combination of letters as for
the aggregate designation acc. 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 acc. to process
and "+" in front of designation code acc. 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 (KU) 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 counting direction at the view to the back side is from right to left and from top to
bottom.
• Vertical breakdown in 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.
5.9
DESIGNATION EXAMPLES OF ELECTRICAL EQUIPMENT ACC. TO KKS
5.9.1
Designation of power generation units - data character G
It is possible to use on this data character either letters or numbers as shown in
chapter 1.3.1. It is important to make space behind this symbol and the block
designation acc. to chapter. The guideline 0AM/13_2 shows in chapter 1.5 the writing
of codes into a row or into several rows.
5.9.2
Use of prefix codes - data character F0
5.1
There are for example more generators in one combined unit. Steam turbine MA. is connected
to generator MK., as well as the gas turbine MB. is connected to next generator MK.;
generator’s equipment of steam turbine is then 1MK., generator’s equipment of gas turbine is
then designated 2MK. (take notice of fact that space is not written behind this number as it is
done for the number designating power generation unit). Occasionally it is more suitable (with
respect to replacement possibility for designation of units) to discriminate such equipment on
data character FN (generator’s equipment of steam turbine is MK10, gas turbine is MK20 etc.).
5.2
Analogously use prefix codes for power outlet:
5.3
Use prefix codes of power outlet for connection without house transformer with average
voltage:
5.9.3
Designation of
transformers
5.1
Designation of
transformers is done inside of the main group B according to following principles:
- Block transformers in group BA
- Start-up transformers in group BC
All transformers for feeding of home consumption always in the group which is on
the site of lower voltage, resp. by direction of the energy flow.
5.2
Designation of outlet transformer 6,3/110 kV of first block.
Transformer is designated according to agreed numbering by following the
chapter 1.3.4.1:
1 BAT81
5.3
Designation of equipment at transformer
Equipment at transformer, for example pumping aggregates, fans, measuring
circuits, subdistributors are designated with the discriminating code valid for
aggregates.
For example the designation of equipment / aggregates at block transformer
BAT10:
Pump unit
Fan
Measuring circuit - temperature
Measuring circuits -pressure
BAT10 AP110
BAT10 AN110
BAT10 CT001
BAT10 CP001
BAT10 GA001
Subdistributor/ terminal cabinet
5.4
Designation of transformer winding
For unambiguous designation, for example for laying are transformer winding
designated on aggregate data character A1A2 by group of letters GT equipment of transformer and on data character AN are calculated from first
to last one by side of higher voltage:
1. winding of lower
voltage GT210
5.9.4
2. winding of lower
Winding of lower
voltage GT220
voltage GT002
Designation of home consumption feeding (switchgear, batteries, charging devices,
converters)
This equipment (big and smaller) are independently on the installation point, classified
already in the breakdown level 1 in alphabetical part (data character F1F2F3).
Numbers on data characters FN serve for the fields numbering, voltage levels or other
agreed designations.
5.1
Switchgear 1
BFA
Switchgear 2
BFB
Switchgear 3
BFC
Third field designation of second main switchboard of power generation unit 1
1 BFB03
5.2
Designation of components in switchboard
Electrical components of switchgear outlet specified for feeding of electrical
drives, transformers etc. are designated with code of particular feeding device.
5.9.4.2.1 For example contactor of condensate feeding pump LCB10AP110 of non
block parts is designated by the following :
LCB10 AP110 -Q01
5.9.4.2.2 Contactor in switchboard specified for feeding of subsidiary switchboard of first
block BJA01 is designated by the following: T
1 BJA01 -Q01
5.3
Battery designation
Designation of first battery 24 V DC of second block.
Battery is designated by the following as for the agreed numbering in chapter
1.3.4.2:
2 BTA21
5.9.5
Designation of control and deblocking cabinets at engine and its components.
The supplementary aggregate code on data character A3 (see chapter 1.3.7)
is used for the accurate identification of particular equipment.
5.1
For example designation of control and deblocking cabinet of pumping aggregate of
feeding water LAC10 AP110 is as follows:
LAC10 GH110P
5.2
Contactor designation in the above mentioned control and deblocking cabinet shall be :
LAC10 GH110P -S11
5.9.6
Outlets to appliances
Each outlet coming out from switchboards for el. appliances
(el. engines, servodrives, heating devices etc.), feeds "aggregate", which is not
designated acc. to the switchgear. Code symbol of this aggregate comprises
of system code symbol and aggregate code symbol. It is efficient to designate
the branch by process code symbol of appliance (principle of author) from
view of functional designation.
As a result to a fact that in the el. documentation is often used designation
next to each other acc. to process as well as acc. to location point, which
sometimes does not have to contain the breakdown code 2 (nor a
discriminating period), it is used in el. documentation for code discriminating of
prefixcode symbols (in details see 1.4.1).
+ BBA
Pumping aggregates LAC10 AP110, MAG20 AP110 and PAC10 AP110 are
fed from switchgear BBA. In the field +BBA01 is for e.g. located the
distribution device (power generation switch etc.) for pumping aggregate
LAC10 AP110. This outlet is designated by process code symbol =LAC10
AP110. Analogously it is done with other outlets.
