2、allations , and parts thereof , by means of differing , incompatible systems. The result was a series of (opera-tions) whose sequence was often irrational.Bearing in mind the scale of power plants being built up to the early sixties , the Plant Designation System AKS could be regarded as adequate fo

3、r the needs of plan-ning and construction engineers at that time.In the meantime, the AKS has been adopted as the main system of identification in a number of convertional and nuclear plants, The operating companies also referred to the “VDEW Guideline for the ldentificaotion of Defects and Down- Ti

4、me in Thermal Power Plants”(VDEW component code). Increased unit sizes , higher rates of automation , and further developments in power-plant technology coupled with the demands made on classification system atics by power plant operators , all called for a uniform and total solution of the classifi

5、cation problem .A working party , consistion of planners , operating companies , authorized inspectors and other authorities , was set up in 1970 with the task of finding such a solution . The result of this joint effort is the Power Station Designation System KKS . This draws clear divisions betwee

6、n power plant installations and systems , and takes full account of the needs of manufacturers , operators , inspectors and other authorities as well as the technical requirements of the mechanical engineering , process engineering , civil engineering , and electrical and control engineering sectors

The KKS-user experience have shown,that a seperation is senceful in KKS-guidelines KKS-application commentaries This was realized in the 3 rev

12、ised edition 1988 and the application commentaries as a additional expedient was produced for the users In the 4. revised edition 1991 further corrections and completions have been added.KKS takes account of other relevant standards such as iEC,ISO,etc. and its principles are laid down in DIN 40719,

13、part 2 or DIN 6779, part 1. The purpose of this publication is to summarize the structure, contents and application of the KKS. Lllustra-tions of the structure , and the code section of the VGB book without definitions(in the Appendix), are used to describe the system.Attention! This publication is

14、only a short information(VGB-edition 1994), lt can only be used for DECODING and not for encoding!KKS Applications at the design unit For their internal use, the design unit have reduced the VGB-KKS code to the specific parts for conventional power plants and nuclear power plants(LWR) The resulting

15、，the design unit Standard Code for Conventional Power Plants” form the basis for the KKS project codes prepared by the design unit for individual power plant projects. These are drawn up in accordance with the conditions specific to the particular project by reducing and allocating the design unit S

16、tabdard Code.The KKS project code contains the designations for all plants and subsystems inciuded in the specific power plant project.For certain large components found in power plants.e.g.steam turbines, gas turbines, generators etc.standardization measures were taken which.apart from the actual i

17、dentification, extended to forming groups in respect of the numbering and in part, to laying down the individual counting digits.The standard designations supplement the design unit Standard Codes to form an essential basis for the KKS profect code.32 ABC for KKSDesignation and type of data characte

18、rsTable 1 summarizes the designation and type of data characters of the breakdown levels for all three different types of designation appearing in the KKS.Process-Related identificationIn this type of designation the entire system is sub- divided according to the function or process since, whether f

19、or mechanical, electrical, control or civil engineering, the equipment units and components must be identifiable in relation to the process.The process-related identification is for many applica-tions the most important designation , since is permits, for example, locations of electrical and control

20、 equip-ment rooms, signals ,and the designations in circuit dia -grams to be related to particular functions.In the electrical and instrumentation control engineering sectors, the equipment for auxiliary services, power supply, open-loop control, instrumentation, protection, etc, is treated as a pro

21、cess engineering function The same applies to structures in civil engineering work.The process-related identification corresponds to the designation block”Plant”in DIN 40719,part 2 This block has the prefix sign“=”.According to the standard the prefix sign can be omitted provided that the designatio

22、n remains unarnbiguous.Point of installation identificationAs with the process-related identification, the KKS is also used to designate locations, principally of electrical and instrumentation and control equipment, but also of mechanical equipment Locations-for example, coordinates, racks and posi

23、tions in cubicles etc-are designated in the breakdown level EQUIPMENT UNIT.The identification letters now used for the Point of installation identification in the breakdown level FUNCTION may be the same as those for the process-related designation. This improves recognition of the designations in t

24、he overall system. Confusion with the process-related designation is impossibple since, according to DIN 40719, part 2, the prefix sign“+”has to be added to this designation block“Location”-when confusion is possible. Resp. the breakdown symbol“full stop”bet -ween breakdown Level 1 and 2 has to be a

25、dded This prefix sign is omitted when there is absolutely no ambiguity-for example, in layout documentsLocation identificationIn order to clearly designate the position of plant, subsystems and equipment in the power station, the buildingstructure and floor is entered at the breakdown level FUNCTION

26、, and the rooms on the various floors of the building structure at the breakdown level EQUIPMENT UNIT The breakdown level ITEM is omitted in such cases.Fire protection section are designated according to the room desigationTable 1 Breakdown Level StructureSerial number of breakdown level0123Name ofB

28、tents of theBreakdown LevelsThe individual breakdown levels of the KKS have an alphanumeric structure thereby ensuring clarity and easy memorization (Table 2)The redundancy specification, required for safety reasons in certain nuclear power station applications, is not relevant for identifcation pur

30、 between them. In such a case, this designation must be agreed upon by all parties concerned, regarding the contents and type of data character(A or N). lt is recommended that an alphabetical symbol be used here, since the next character F0(prefix number)is numerical.The breakdown level“OVERALL PLAN

31、T”can be omitted when the designation used in the power plant is otherwise unambiguous.Breakdown Level 1,FunctionPrefix numberAor NNAAANNAANNNAAANNIf in the overall plant two or more identical subsystems are to be identified(2 boiler plants, 2 turbosets, 2 nuclear heat-generating systems, 2 structur

Each prefix number is valid only in the area of the function concerned and refers always to the alphabetical symbol Fwhich follows it On no account is it to be considered as a substitute for the counting of system section
