1 OBJECT KKS System will be used for component designation at Pilar Combined Cycle Power Plant. Sub-suppliers of packaged units will be requested to apply KKS designation system. Nevertheless, those companies which are not able to use KKS system will not be discarded as potential suppliers and component designation within packaged units might not be according to KKS system.
1.1 AIM OF THIS DOCUMENT The purpose of this document is to set the basis for the application of KKS system in this project. The fourth revision of KKS “Kraftwerk Kennzeichen System” (Power Plant Code System), 1991 Edition has been used. The application of KKS System is intended to set an unambiguous and uniform denomination of every single component of the entire power plant. For all system groups of the plant, this uniform coding system will be applied. The companies implied in this project, which use the KKS system, shall follow the instructions of this General Procedure. Extended application of the KKS system is to be executed by each supplier for its scope of supply in accordance with the latest English version of the “Kraftwerk Kennzeichen System” (KKS) of the VGB expert committee “Technische Ordnungssysteme” (Tech. Classification Systems). Any deviation, changes or additions that any of those parties would like to make shall be requested in written to SENER. Before applying any deviation, a writing confirmation from SENER must be received.
1.2 COORDINATION AND HARMONIZATION An interface coordination matrix is defined (Annex G) in order to avoid possible conflicts between different parties when choosing numerical digits for FN numbering of Breakdown Level 1. Another objective of the coordination matrix is to make the codification process more dynamic without consulting the other parties. Counting ranges have been preliminarily established in order to harmonize their application criteria for the complete Power Plant. Codes and counting ranges in the interface coordination matrix will be completed as required during the project. Terminal points represent a delimitation of the system identification and both parties must use the interface coordination matrix. Using the coordination matrix, different parties use different numerical digits for FN system numbering of Breakdown Level 1 in order to avoid conflicts. In this way, piping and components codification do not depend on other parties.

STRUCTURE AND APPLICATION IDENTIFICATION SYSTEM KKS
OF
THE
POWER
STATION
2.1 FORMAT OF THE KKS-CODE 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 designation structure, with a maximum of four breakdown levels, was created for all three types; the units referred to becoming smaller from left to right. The next table shows the breakdown levels.
Serial number of breakdown level
0
1
2
3
Name of breakdown level
Overall
Function
Equipment
Component
Example
Unit
System
Pump Unit
Pump
Although these numbering code elements are subject to agreement on a project, the next guidelines shall be applied: •
As a rule numbering starts a new when one of the preceding code elements changes.
•
Numbering may be consecutive or grouping.
•
Numbering need not to 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, except as modified below.
•
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.

•
The counting at the counting data positions restarts every time if there is a change in the previous classification data positions.
•
It is recommendable to skip numbers for having latitude for later additions in the course of planning.
•
The counting of different types of units of the same kind is effected by counting ranges.
•
Once a counting number is fixed for a particular item (component, pipe section) it will not be changed anymore even if in the run of continuous engineering other rules of coding are infringed.
•
If a certain item will be removed in the course of planning, a counting number may not be reused.
When the KKS-code is written in single line no blank must be inserted. Example A3LAB10BB001 When the KKS-code is written in more than one line, the wraps are placed between Breakdown Level 1 and 2. If Breakdown Level 3 is applied, the wraps shall be placed between level 1, 2 and 3. All lines are to centralise. Examples A3LBA10 BB001 KT001
A0GAF10 AP001
Breakdown Level 0, 1 and 2
Breakdown Level 0, 1, 2 and 3
2.2 PLANT COUNTING DIRECTION The counting direction is determined by the direction of fluid flow and/or signal flow. For components connected in parallel, rooms, cubicles, etc. within the project, the following counting directions are stipulated: •
From South to North
•
From West to East
•
From Ground to Top

To be defined if required
F1, F2, F3 System classification These alphabetical symbols are used to classify and divide the overall plant into subsystems, systems or building structures. The function-oriented system classification of the plant is effected at data places F1, F2 and F3 according to the KKS function code. The function code letters used specifically in this project are listed in Annex A. FN
System numbering The numerical digits count and subdivide the unit (e.g. lines, cubicles, floors of buildings, etc.) coded in the last alphabetical digits.

SPECIAL CONSIDERATIONS
The following specifications, related to the counting digits FN, AN and BN, shall be used: •
Breakdown of the plant systems into subsystems, is effected with priority in the FN counting digits of the Breakdown Level 1.
•
The counting sequences in the Breakdown Level 1 are, as far as possible, employed in increments of ten (starting with 10) in order to have latitude for later additions, if required. Counting in the Breakdown Level 2 should preferably start from 001 on for equipments, valves and for piping. Example: 10LAB10AP001
For piping, valves, measurement devices and cables, a grouping in counting is envisaged in the Breakdown Level 2 to distinguish them in various types.
4.1 KKS LABELS FOR UNITS, APPARATUS, VESSELS AND VALVES Such labels shall give at least the information shown below. It is allowed to write more information. “KKS Breakdown Level 0 and 1” “KKS Breakdown Level 2”
4.2 IDENTIFICATION OF PIPING SYSTEMS 4.2.1 Symbol Use Piping systems identification is carried out using “flags”. The direction of the “flag” shows flow direction inside the pipe. The flag shall contain the Breakdown Level 0 and 1 in the top line and the Breakdown Level 2 in the bottom line. The nominal diameter values are placed on the opposite side of the line which presents the pipe. Both pipe specification associated to the line and the type of insulation are included in the area.

4.2.2 Delimitation of KKS-sections Delimitation of system identification in the Breakdown Level 1 is represented by a hollow needle. Example:

KKS APLICATION GUIDE
Doc. Nº. PLR-SRTP-GD-0029 Rev.: 0 Fecha: 21/04/08
Página 12 de 72
For clearer representation of the coding sections, it is to be made sure that the needles are not situated directly at the branching or junction point, but close to it at the concerned line. It is to avoid that two needles are placed one after another along a streamline at a branch or a joining point. The T-fitting in the example below has to belong unequivocally to a KKS section. Example: 10LBA21 BR001
10LBA22 BR001 1LBA30 BR001
10LBA22 BR001
one too many needle
1LBA30 BR001 1LBA23 BR001
one too many needle
WRONG CORRECT As it has been said above, delimitations of system identification in the Breakdown Level 1 are represented by a hollow needle. On the other hand, delimitations of system identification in the Breakdown Level 2 are represented by a solid needle. Example:
4.2.3 Rules for numbering on P&I Diagrams 1) Lines of a main flow shall be numbered at the Breakdown Level 1 preferably in increments of ten beginning with 10 and continuing with 20, 30 and so on. 2) If a main line is branched into parallel lines, such parallel lines are to be numbered by using the next ten’s digit of the upstream main line for the beginning of the counting of the parallel lines.

Página 13 de 72
For instance, if the main line is numbered by 20 the branched lines will get numbers as 31, 36, etc. Using a number ending with zero should be avoided at a line in parallel to indicate there is another line with the same function. When the parallel lines join together a step to the next ten’s digit shall be affected (see example). Example:
2LAB21 BR002
10LAB21 BR001
10LAB30 BR001
10LAB20 BR001 10LAB22 BR001
10LAB22 BR002
3) Numbering for several piping legs is also effected at the first Breakdown Level in increments of one. Example: 10GAF63 BR001
10GAF62 BR001
10GAF60 BR001
10GAF61 BR001

4) If the fluid undergoes a significant change in parameter (e.g. by pumping, preheating or throttling) the line will be ascendant numbered in the second Breakdown Level in increments of one in flow direction. Example: When installing a pump: 10PGM50 BR001
10PGM50 BR002
10PGM50 AP001
When installing a heat exchanger: 10PGM50
10PGM50

Due to the use of the interface coordination matrix, shown in Annex G, there could be some cases in which the KKS application criteria explained in this application guide cannot be strictly followed. This is the case in the interface points between two different Suppliers.
4.2.4 Distinguishing of subclasses within one KKS system section at the Breakdown Level 2 Counting Ranges for pipe codes at Breakdown Level 2 Code ranges of counting sequences are employed in order to distinguish between various piping types in the KKS. The pertaining stipulations can be found in Annex C. Counting Ranges for valve codes at Breakdown Level 2 To distinguish between various valve types in the KKS code, certain counting ranges are used. The prescriptions of the counting ranges of valves are contained in Annex D. Counting Ranges for equipment at Breakdown Level 2 are from 001 to 999 in a sequential order.
4.3 INSTRUMENTATION AND CONTROL (SENER STANDARD) The measurement points are represented by an oval thereinafter called measurement circuit. In the top line, the so-called function letters are entered. The letters to be used are according to the American standard ISA. In the bottom line the complete KKS code of the measurement point is shown. Top Line : ISA code according to the Annex F
Bottom Line 2: Complete KKS- code of the measuring point

4.3.1 Signal Codification The code for all the instruments, equipments, power centers and cabinets will be made of the 1 and/or 2 breakdown levels. The 3 breakdown level will be used for the signals. The following criteria will be taken into account: − Instrument signals The instrument signal codes are similar to the instrument codes, formed by the ISA code as the prefix and the KKS code as the final part in the global code. − Control signals These codes will be the 3 breakdown level and will be the prefix of the signal KKS code for a faster identification of the signal instead of putting after the equipment, instrument or cabinet code. The codes to be used are defined in Annex C If the motors are double speed motors, we will distinguish the signals for one or another speed adding a character to the prefix indicating the fast speed F, or the slow speed S.
4.4 CABLING FOR ELECTRIC, I&C SYSTEM The cable codes consist of Breakdown Level 0, 1 and 2, plus an auxiliary end level which indicates the cable service. The 0, 1, 2 levels are from the supplied system.
