This rule does not refer to direct measurement circuits, which apply to technical installation and physical variable.
Exceptions are junction boxes for main machine sets and heavy machinery, and junction boxes in electrical and control and instrumentation cubicles and cabinets; these are identified on breakdown level 1 according to the associated main machine or heavy machine and cubicle or cabinet respectively. Due to the size of power plants and the fact that the large number of parties participating are all in different locations, communication problems arise which can incur costs which cannot be estimated in advance.
VGB-Be-eBook: KKS Identification System for Power Plants
Filters in ventilation and air conditioning systems. Closed-loop controls are identified according to identificaiton controlles variable and not after the measuring circuits which serves the control or the final control element on which the control acts.
Their use for any intended purpose is subject to agreement between the parties to the project. The AN number must consist of three digits.
KKS Identification System for Power Plants – eBook
System-related identification is expedient where the supported items are positively assignable to one system. Rules on the Keys Kraftwerk – Kennzeichen – System KKS was published in 1st edition by the VGB and is now the basis for the designation of installations and subsystems in power plants. A – Grid and distribution opwer for electric power plants, thermoelectric power plants and heating plants Control and instrumentation equipment which serves more than one main group may be identified under main group C for control and instrumentation, e.
Requirements to be met by the Identification System To perform the set tasks the Identification system sydtem be capable of satisfying the following requirements: System numbering must consist of two digits. The AN number of breakdown level 2 is used to number the items of equipment classified in A1 and A2. QCG Central chemical supply free for use idntification.
Identification System for Combined Cycle Power Plant (KKS coding)
Where measured data are corrected e. It is not allowed to use any other letters.
The prefix symbols may be omitted if the information contents of the codes remain unambiguous. Log In Sign Up. AN numbering may be consecutive or grouping. Equipment unit code consists of 2 letters data characters A1 and A23 digits data characters AN and sometimes 1 letter data character A3 which can be, and often is omitted.
Where signals or measured data are used to limit or suppress the original measured data, the processed output signals retain the code of the original measured data. Where an equipment unit serves as an interface between ofr or more systems, its system code is assigned on the originator principle, i.
Numbering starts anew when one of the preceding code elements changes. There are also cases of deviations consisting in using the dividing symbol twice, and AN, e.
The additional code is not an alternative code for the components identified under breakdown level 3.
Identification System for Power Stations (KKS)
EB – Conditioning of signals related to single drive control. Point of Installation Identification Spaced notation promotes the comprehensibility and idnetification quality of codes. Increased unit sizes, higher rates of automation and further developments in power-plant technology, coupled with the demands made on classification systematics by power plant operators, all called for a uniform and total solution of the classification problem.
Control and Instrumentation Equipment I – 5. Physically separate rooms in structures are identified by numbering, grid squares in the outdoor area by coordinates. Bearing in mind the scale systsm power plants being built up to the early sixties, the Plant Identification System AKS could be regarded as adequate for the needs of planning and kkd engineers at that time.
F3 of the principal process-related task.
In this application, however, a suitable identifier such as a prefixed Y should be used to indicate that a software coding unit is concerned, thus to rule out confusion with process-related codes. Subdivide for this aim the panel elevation into planes: Z — Workshop and office equipment Identification in data character A2 is governed by the physical variable.
Format of Code I – 2. It should be decided on a case- to-case basis which numbering convention is best suited to the extend and structure of the systems and plants to be identified.
Gated analog signals representing physically similar direct measured variables are identified by means of a set number, e. Transducer Racks, Supports, Frames This auxiliary equipment is identified on breakdown level 1 using the code for the equipment location structure codewith the exception of auxiliaries for main machine identificaation and heavy machinery system code.
Help Center Find new research papers in: On breakdown level 2 supports should be identified by BQ. Usually the code is written above the line: If several process-related systems are situated in one structure we designate this structure according to the main, most important system. The flag points in the direction of fluid flow.
A — Mechanical equipment Drains and vents are identified as far as the final isolation element — including double valves — or as far as the open outlet as part of the drained or vented system originator principle.
Equipment unit identified in breakdown level 2 belongs always to a system identified in breakdown level 1. General Notes I – 5. The planning, construction and operation of power plants was based in the past on attempts to identify odentification and parts thereof by means of differing incompatible systems.
The additional code can be omitted. However the following principles apply: Any combination of alpha and numerical symbols appropriate to the requirements is acceptable for the identification of connections.
Q — Auxiliary systems
