EA — Conditioning of signals related to functional control group. VGB-Be-eBook: KKS Identification System for Power Plants Originally the titles of the breakdown levels were based on the process-related code: System-related identification is expedient where the supported items ysstem positively assignable to one system. Introduction Identification System is based on the Kraftwerk — Kennzeichen — System KKS This System is the basis for the standard and clear identification of all installations and subsystems in power plant. If several process-related systems are situated in one structure we designate this structure according to the main, most important system. Steam, water, gas cycles Q.

Daidal Special structures, ducting identidication are designated in main group F1 with coding letter U and in subgroup F3 with following coding letters: The additional code is not an alternative code fir the components identified under breakdown level 3. D — Loop control circuits Subsequent isolation and pressure equalization valves in the measuring circuit are components of the measuring circuit and therefore classified as KA.
EA — Conditioning of signals related to functional control group. These analog signal processing elements receive the code of the equipment unit concerned. Equipment unit classification Serial no. L — Steam, water, gas cycles Originally the titles of the breakdown levels were based on the process-related code: AL According to cubicles, divisions, sections etc. Filters in ventilation and air conditioning systems.
Format of Code I — 2. Coding letters and designations of the main groups F1 as given in the Function Key: N — Process idetnification supply for external users e. This draws clear divisions between 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.
On breakdown level 2, the individual windings are classified but not on a phase-specific basis by means of GT for transformer equipment and numbered starting on the high-voltage idejtification. Coding letters of the main groups F1 identificatiion specified on next and the subdivisions in F2 and F3 are given in the present chapter II. Special Rules for Mechanical Engineering Click here to sign up. Planys data characters in parentheses may be omitted if the code remains unique.
Redundant zeros must be written e. Control and Instrumentation Equipment I — 5. A Grid and distribution systems B Power transmission and auxiliary power supply C Instrumentation and control equipment D Instrumentation and control idenyification for use only when function codes CM to CT are insufficient for the identification of system combinations The subdivisions in F2 and F3, are given in the applicable Function Key.
When technical installations differs only with counting signs of installation it is necessary to assign to a secondary variable counting signs like for one of those installations e. Safety equipment, consisting of safety valves and their associated piping, are assigned to the system to which they are connected.
Equipment Unit Identification In the process-related code which is the most important and mostly applied type of codes in every branch of engineering, the entire system is subdivided according to the function or process. Installation Space Code Serial no.
No one of these symbols can be omitted. X Signal origins Y Signal applications Z Gated signals No generally valid rules have been made for signal and application areas. A Grid and distribution systems B Power transmission and auxiliary power supply C Instrumentation and control systems D Instrumentation and control systems E Conventional fuel supply and residues disposal F Handling of nuclear equipment G Water supply and disposal H Conventional heat generation J Nuclear heat generation K Nuclear auxiliary systems L Steam, water, gas cycles M Main machine sets N Process energy supply for external users e.
The contents of this designation in KKS, is left for coordination for particular power plant. Installation Unit Code Serial no. 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. It should be decided on a case- to-case basis which numbering convention is best suited powwer the extend and structure of the systems and plants to be identified.
The allowable notations are fixed. This is subject to agreement between the parties to the project. System code System code consists of three letters and two digits. Skip to main content. The flag points in the direction of fluid flow. Wherever possible, all three alphabetical symbols are permanently identificatio, including their associated boundary constraints and task allotment in modern power plant technology. Generally valid rules on the use of FN ksk are not expedient.
There are also cases of deviations consisting in using the dividing symbol twice, and AN, e. The additional code can be omitted. Related Posts
