Project: STANDARD
1 INT RODUCT ION
The design of complex technical plants involves an enormous number of data to be exchanged
between the parties concerned. The identification of plant systems, sections and individual
components therefore has to be centralised for the whole plant.
The identification system provides a common language for the design and documentation of the
scope of work and services. Due to their complexity, modern power stations, where civil works,
mechanical- and electrical sections as well as electronic systems are related to each other,
require an identification system to avoid disagreement between the parties and unforeseeable
costs and time delays during construction.
The identification system KKS (Kraftwerks-Kennzeichen-System) represents a technological and

logical classification for modern power stations. All plant sections and components will be
identified on a system-related basis in order to satisfy the requirements of the manufacturer, plant
owner and operators as well as experts in view of design, erection, operation and maintenance.
KKS includes:
- Design and construction

- Verification
- Assembly
- Manufacturing
- Erection
- Acceptance
- Documentation
- Operation
- Maintenance
- Recruiting and replacement administration
- Outage statistics
- Plant accounting
- Industrial economics
The KKS identification system for power stations was developed by the KKS-workout involving
designers, plant operators and power authority members and was published in two sections by
the VGB-Verlag 1989:
- KKS-Guidelines
- KKS-Key
The 5th edition containing complements to the KKS-Key was published in 2003 by the
VGB-Verlag publishing house.
The indicated breakdown levels 1, 2, 3 in this document are those dated 2004.
The Explanations for Hydro Power Plants VGB-B 106 D1 from July 2004 are included
(see chapter 6).
The KKS in its characteristics will be based on IEC 81346, DIN EN 81346 and
DIN ISO/TS 16952-10.
The following information represents a general overview regarding the structure and use of KKS.
The KKS-Key given in part two will form a basic platform for KKS utilization for the sole internal
use of ANDRITZ HYDRO GmbH for plants designed and executed by ANDRITZ HYDRO GmbH.

Project: STANDARD
2 STRUCTURE OF KKS
2.1 Breakdown Levels

An individual identification code consists of a maximum of 4 breakdown levels:

The classifying part of the cable identification is defined by the both termination points at
the switchboards, whereby the function identification which is leading in alphabetical order
will prevail. From sub distributors to components, identification according to sub distribution
identification is possible.
The first position of the counting number of the resource indication serves the voltage level
for the classification
0001 - 0999 Power cables >1kV

1001 - 1999 Power cables <1kV
2001 - 2999 Control cables, Controlling >60V
3001 - 3999 Cables for measurement >60V
4001 - 9999 Cables for control and measurement <60V
Details of application 4001-9999 are subject to agreement between the parties to the
project.

Project: STANDARD
3.7 Identification of Documents

Documents that will be supplied and are necessary for operation of the plant are:
- general technical documents

- electrical and control and instrumentation documents
- mechanical documents
- civil documents
For these documents, a separate identification will be provided.

This identification of documents serves to address a document and to define its location in
the whole documentation - regardless of the drawing numbers of the different
subcontractors.
The documentation identification consists of 3 parts:
- Equipment identification: KKS-breakdown level 0-2

- Type of document key: classified by a combination of characters
- Counting number

other in the aggregate breakdown level by means of the supplementary character A3. This
applies to temperature measurements with dual thermocouples, flow measurements with
multiple probes as well as double secondary current transformers or voltage transformers
connected to loops.
Example: temperature measurement with dual thermocouples
Loop A
MEX10CT001A
MEX10BR001 MEX10CT001
Loop B
MEX10CT001B
Should a dual thermometer be used as a sensor, whereby only one connection is used
(second connection as spare), then only one loop number will be assigned and the
supplementary character A3 will not be used.
Example: loop with multiple probes
MEX10CF001A
MEX10BR001
MEX10CF001
MEX10CF001B
MEX10CF001C

Project: STANDARD
3.11 Logical combination of loops

The general rule for logical combined signals is that the code of the signal to be processed,
and thus the physical measurement, will be retained as far as possible. Logical combination
of measurements of the same type (i.e. both pressure, multiple temperatures, etc.) will be
distinguished by a certain character, e.g. 9, in the position AN and keep the designation of
the physical measurement in the position A2 .
Example: Calculation of a temperature difference
CT011 CT012
Temperature
difference
CT901
When signals are used to limit or suppress a measurement value, the output signal of the
signal processing keeps the character designation of the original measurement and only the
first character of the component key will be changed from *X* to *Z*.
Example: Suppressed alarm
..... CP303 XG01 ..... AP001XB01

Pressure after Pump is ON
pump < min
10 0
&
..... CP303 ZG01
Alarm: Pressure after pump < min

Project: STANDARD
3.12 Identification of Loops
3.12.1 Identification of direct loops

Direct loops will be designated with *C* in the data character A1 in breakdown level
2. The position A2 corresponds to the measured physical value (e.g. pressure,
temperature) in accordance with DIN 19227.
In breakdown level 1, the loops are assigned the identification of the system of
which the loop is a part. In other words, the loop will be named after the system
where its measurement probe is located.
Example 3.12.1/1
System 1 System 2
CT001 CT002 M CF001 CP001
CT001
Medium-direction of flow
Example 3.12.1/2
Medium-direction of flow
MEX10 MEX10
MEX10CP001 MEX10CP002

Project: STANDARD
The measured physical value, and not the measuring principle, determines the data
character of position A2.
Loops for the same physical value within a given system (FN) should be assigned
increasing numbers according to material and energy flow. Should new loops be
added or loops deleted, the other existing loops should not be re-numbered.
Seeing that loops normally have a specifically assigned designation in the

equipment unit key (breakdown level 2), measurements on a given piece of
equipment will not be named after the equipment but after the loop. These include
level measurements on tanks, analog position measurements of valves, frequency
measurements, motor core temperatures, etc.
Example 3.12.1/3
CL013
CT008
CL012 M M
CG003
CS008
AA003 AP003
In this example there are loops for the individual components of the system. The
level measurement on the tank will not be named after the tank, but will be assigned
an individual loop designation. Similarly, the frequency and temperature
measurements on the pump motor are individual loops. The same applies to the
valve analog position measurement. By means of careful number assignment for
position AN, it is possible to retain the relationship to the equipment (e.g. valve
AA003 with positioning loop CG003).

Project: STANDARD
3.12.2 Identification of indirect loops

As on the contrary to direct loops, indirect loops are not used for the direct
measurement of a physical value, but used, in combination with other loops, for the
calculating and compensation of measurement values. The signal is not generated
directly from a process measurement using probes, but by mathematical calculation.
The resulting new signals represent new or different information.
In order to clearly differentiate these signals and their associated equipment from
the related direct process signals, the data character in position A1 will be assigned
*F* (indirect loop) instead of *C*. The data character 2 will be assigned a letter
according to its physical value (DIN 19227), as for the direct loops.
Example 3.12.2/1:
Pressure and temperature compensated flow measurement using the original
measured value
CP011 CF009 CT015
Korrektur
CF009 FF009

Project: STANDARD
Measured value processing of signals of different physical values will be assigned

*U* (logical combination of differing physical values) to data character A2.
Example 3.12.2/3:
Calculation of a value from 2 different physical values
e.g. enthalpy.
CP001
Y=

Example 3.12.2/4:

e.g. limiting curve

Example 3.12.2/5:
Calculation of a value from 2 different physical values, whereby one is a calculated
value and the other a direct measurement.
e.g. flow with mass compensation
PD001
Y=
CF001 FF001
f( x Q)

Project: STANDARD
Example 3.12.2/6:
Calculation of 2 output signals using a maximum selection from 2 groups of 3
measured values, which are obtained from a selection gate
e.g. dual line HP-steam system

place beforehand. Each system contains a flow measurement with 3 transmitters
at one measurement point, with separate compensations, for the protection criteria
for the HP-steam flow of a dual line steam system.

following 2 numerical data characters.
Seeing that the required guidelines for the signal designations of the equipment and
the application data characters are also dependent on the related documentation
technology, the following examples do not show signal designations that are valid
generally for all projects, but can be used basically or shall be used if there is no
other standard available. The manufacturer-specific guidelines must be referred to,
and implemented for each project individually.
The signal designation of the individual derived process values and C&I signals are
fixed by the ANDRITZ HYDRO Standard. Exceptions allowed only by permission of

5.2 Binary signals (contacts) and limit values from signal conditioning
5.2.1 Designation letter (signal range)

G = contact (binary process signal incl. conditioning for contacts)
H = limit value (derived from analog measurement signals)
5.2.2 Signal numbers for binary process signals (contacts)

Most of the binary process signals (contacts) are signals from field instruments as
follows:
-limit switches
-pressure switches
-temperature switches
-level switches
with only one contact. Each instrument will have an individual KKS-Number.
The contact/signal from each field instrument will get therefore the same signal
code:
XG01 for normally open-contact, and
XG51 for normally close-contact.
For field instruments with tandem (or triple) switches with same limit value, we
recommend:
XG01/51 for the first switch
XG11/61 for the second switch
XG21/71 for the third switch
For field instruments with two (or more) switches with individual limit value, we
recommend
odd-numbers for high-limit values, even-numbers for low-limit values:
XG01/51 for the high-limit value
XG02/52 for the low-limit value
XG03/53 for the high/high-limit value
XG04/54 for the low/low-limit value
XG05/55 for the high/high/high-limit value
XG06/56 for the low/low/low-limit value
5.2.3 Signal numbers for limit values derived from analog process signals
The analog process signal will have normally the signal code XQ01 for standard
transmitters.
The derived binary limit values will be produced internal in the DCS/PLC, standard
as follows:
odd-numbers for high-limit values, even-numbers for low-limit values:
XH01/51 for the high-limit value
XH02/52 for the low-limit value
XH03/53 for the high/high-limit value
XH04/54 for the low/low-limit value
XH05/55 for the high/high/high-limit value
XH06/56 for the low/low/low-limit value

units as well as transformers and inductors including the auxiliary systems such as compressed
air supply, protection and control systems.
The following rules and recommendations have to observed for this purpose.
The process related sections of high voltage switchgear are identical to the switchgear
cubicles.
Bus couplers and busbar metering panels should be identified in the numbering section
as 00.
If distinctions necessarily for busbar systems (double busbar) are like that should these
done in the number block.

Project: STANDARD
Identification of power transmission (BA _ )
All installations from excluding the generator terminal to excluding the high voltage side of the
generator transformer are part of the power transmission.
These cover:
Generator leads including neutral, earthing switch, brake disconnector, surge voltage
protector, measuring transducer, earth fault reactors and auxiliary cabinets.
Generator circuit breaker including auxiliary systems and cabinets.
Generator transformer including cooling unit and cabinets
The reason is a standardisation of many years in the generator division.

The generator leads should be subdivided into subsystems and a decadic numbering in ascending order
should be used from excluding the neutral in direction of the generator transformer.
With single pole leads the outer contactor may be identified in the units place.
The interfaces between subsystems should be established according to the devices installed in the leads.
The ANDRITZ HYDRO standard identify as follows:
1BAA10 Generator busduct

1BAB10 Generator neutral
1BAC10 Generator switchgear
1BAT10 Generator transformer
1MKA10 Generator
1MKC10 Excitation

Project: STANDARD
Identification of low voltage distributions (BF_ till BR_ )
These function levels are not described in the VGB 106 D1.
The KKS standard key is to be used as already shown in the example 3.8/10.
Identification of battery systems (BT_ )
The VGB does without this function level. This is explained in the next paragraph. ANDRITZ
HYDRO uses however these, because it does not follow the recommendation of the VGB but
follows the KKS key (see example 3.8/10).
Identification of DC systems (BU_, BV_ )
A separate function level BT_ for batteries and battery chargers is not included. An interdisciplinary code
BU_ for the 220VDC system and BV_ for the 24VDC system is recommended so that the functional
correlation of the components of a grid system becomes apparent in the identifier, too.
Due to use of many years of standard KKS key with ANDRITZ HYDRO extensions for further
voltage levels (110VDC and 48VDC) is not converted this recommendation. (see example 3.8/10)
Identification of protection equipment
The individual protective functions are generally assigned to the unit which can be protected.
Where a higher level protection equipment, which encompasses various units, is to be identified,
the classification may be selected from key part C_ _.
CH_ generally identifies cubicles for protection equipment.
MKY, MLY Generator protection (e.g. over current, over voltage, impedance, earth fault)
MKC, MLC Excitation protection (e.g. over excitation, under excitation)
B_T Transformer protection (e.g. differential protection, Buchholz protector)
A_ _ Busbar differential protection
MY_, CHA Unit differential protection
U_ _ Security services (e.g. burglary)
CYE Fire alarm system
SG_ Stationary fire protection system
Identification of phase switches
The phase switch is classified as BAC in the same manner as the generator circuit breaker.
BAC10 Generator circuit breaker

BAC20 Phase switch

Project: STANDARD
Identification control and engineering equipment (C_ _ )
Only super-ordinate systems or several systems are grouped in the function level of "C _ _". If it
is a single function control than it is denominated according to their function.
Typical are:
MEY10DG100 Opening control
MEY10DE100 Load control
MEY10DS100 Speed control
LNY10DF100 Discharge control
MYB10EY100 Protective functions (turbine and generator on mechanical failures)
BYA10 Open loop control for auxiliary power supply and emergency power supply
CBP10 Synchronization
LNA10DL100 Level control
The control is usually realized over programmable systems, which contain more than one
function. Further belong to also diagnostic and monitoring systems as well as operating and
monitoring functions.
It is to differentiate whether the control is cabinet-oriented or bus-oriented denominated. The

ANDRITZ HYDRO used so far the cabinet-oriented denominating. In the VGB D1 guideline now
also the bus-oriented denominating is recommended ("CR_"). This function level is at the
moment not in the ANDRITZ HYDRO KKS key available and if necessary to be inquired. This
denomination is often not clearly to be classified due to the multiple functions.
The function levels are documented in the ANDRITZ HYDRO KKS sufficiently.

Project: STANDARD
The technical equipment e.g. aggregates are classified and numbered here.
Identification of subassemblies of the machinery (H_ )
The wicket gates are subassemblies of the turbine casing and are identified as HA
The runner blades are assigned to the runner and therefore they are classified as HB
MEA20HA010 MEA20HA180 Guide vanes

MEA20AS010 MEA20AS020 Servomotor
MEA20AS100 Operating ring
The runner is identified in the same manner as the wicket gate.

Project: STANDARD
Identification of valves (AA) and pipings (BR)
There are different starting points possible.

The ANDRITZ HYDRO standard committed itself to the equipment structure and have these very
exactly standardized. The VGB guideline however classify it on a functional structure. Thus this
structure cannot be converted.
AA 001199 Valves in pipings
AA 301399 Valves in measuring circuits (if an identification is required)
AA 401499 Valves in drainage, discharge and flushing pipings
AA 501599 Valves in vent pipings
AA 601699 Valves in sampling pipes
AA 701799 Safety valves
BR 001199 Pipings in general
BR 301399 Measuring pipings (if an identification is required)
BR 401499 Drainage, discharge and flushing pipings
BR 501599 Vent pipings
BR 601699 Sampling pipes
BR 701799 Safety valve pipings
The ANDRITZ HYDRO numberings are shown in the breakdown level 2.
Main piping including the associated valves are numbered in decade steps.
Decade steps take places if the functional group is changed. See example 3.8/6
Secondary piping are numbered sequentially to the main devices (decade). If subordinated
devices are present such as pilot valves, these can be denominated also after the main
aggregate with an additional letter such as AA011A.
Identification of electrical equipment (G_ )
Switchgear assemblies
The denomination is here aligned to the function of the switchgears.
The ANDRITZ HYDRO standard partly deviates here from the VGB Guideline.
ANDRITZ HYDRO uses for a group only the third digit during the VGB all three digits use.

GS 0 0 0
0 Low voltage switching device 1 Busbar 1 Number of poles
1 Circuit breaker 2 Busbar 2
2 Disconnector 3 Busbar 3
3 Load switch 4 Busbar 4
6 Earthing switch 6 Bypass busbar
8 Converter switch 7 Auxiliary busbar
9 Line
The ANDRITZ HYDRO numberings are shown in the breakdown level 2.

Project: STANDARD
The single line shall once again clarify the ANDRITZ HYDRO standard.
Transformation equipment (transformer winding)
The following numbering system is only important if the transformer windings are to be
differentiated. The transformer is according to standard with GT 100 to denominate.
If differentiated between higher and lower voltage side the higher voltage side with 100 and the
lower voltage side with 200 are to be denominated.
Is it however a multi-winding transformer with same voltage level by 210 and 220, with different
by 200 and 300 are to be denominated.

Project: STANDARD
Identification of not electrical measuring circuits (C_ )
Here is also a difference to the VGB guideline
ANDRITZ HYDRO VGB guideline

Standard
001 ff analog 001099 analog
301 ff binary 101199 binary
401 ff testing
501 ff local 301399 local
901 ff virtual 901999 virtual
See also in breakdown level 2
Multiple tapping points of measuring circuits is shown in example 3.10
Identification of electrical measuring circuits (CE)
The numbering system is alike up to the frequency measuring (VGB 401-499).
001099 Combined measuring

101199 Current measuring
201299 Voltage measuring
301399 Power, resistance, impedance, etc.
501599 Frequency measuring
601699 Earth fault, phase failure
900999 combined calculated measurements
See also in breakdown level 2
Component code
The identification divides between electrical and non electric components. Electrical components
have a minus in the first digit.
Normally two digits for the numbering are used. If necessary it can extended however by one
digit.
The remaining defaults are sufficiently described in the breakdown level 3.
Signal code
The structure of the signal code is in chapter 3.5, the exact explanation and the ANDRITZ
HYDRO standard is represented with examples in chapter 5.
The letter combinations (chapter 5.1.2) of the ANDRITZ HYDRO standard deviate not from the
VGB guideline, but are only partly more detailed. Likewise the number block in chapter 5.2
respectively in the breakdown level 3.

7 INT EGRAT ION OF G E (G ENERAL ELECT RICS) IDENT IF ICAT ION

SYSTEM IN KKS
General Electrics, a partner of ANDRITZ HYDRO, uses ANSI (American National Standard
Institute) as identification system for power plant components. ANSI is a common used
identification system in the United States. To define control and instrumentation interfaces
between GE scope of supply and ANDRITZ HYDRO the GE-identification code is integrated.
Consumer and signal codes are integrated as follows:
KKS ANSI
Breakdown level 0 1
