2. KKS

Purpose of KKSThe Identification System for Power Stations „KKS“ (Kra ftwerks Kennzeichen System)

serves to:

� identify plants

� sections of plants

� items of equipment

in any type of power station, according to:

� task

� type

� location

It is to be used by all engineering disciplines for

� planing

� licensing

� construction

� operation and maintenance

Requirements on KKS

Requirements on KKS:

� Uniform identification for all types of power station and any connected processes

� Sufficient capacity and detail for identification of all system, components and structures

� Consistent identification for planning, licensing, construction, operation, maintenance and wastemanagement

� Consideration of national and international standards

� Non-language-basewd coding to ensure international usability

� Application in computer processing

Types of identification codes

Process-related identification

� Process-related identification of systems and items of equipment according to their functions in mechanical, civil, electrical and control and instrumentation engineering

Location identification

� Identification of locations in structures, on floors and in rooms and also of fire areas and topographical stipulations (surface area grid)

Point of installation identification

� Identification of points of installation of electrical and control and Instrumentation devices in installation units (e.g. in cabinets, panels, consoles)

Point of installation identification

The mounting space code. which is preceded by a fullstop symbol, specifies the exact installation locationby means of coordinates.

The coordinates are established in the followingmanner:The height of a mounting space, for instance, in acontrol cabinet, is divided into several identically sizedinstallation levels. Each installation level is identifiedwith a letter from top to bottom beginning with A. Thisletter specifies the first position in the coordinate. It ishighlighted in orange In the graphic.

If an installation level is divided horizontally, thesedivisions are likewise assigned letters, also beginningwith the letter A. This letter specifies the secondposition in the coordinate; it is highlighted in green inthe graphic.

The three characters identify the slot in an installationlevel and are numbered from left to right beginning with 001

3. Siemens Documentation Structure

Overall documentation structure

Overall documentation structureOperating Manual (Overall Plant) - TO

The Operating Manual contains necessary information for the staff operating the power plant as overall plant.

Operating & Maintenance Documentation - TP

The Operating & Maintenance Documentation comprises technical documents and data required for the description of :

� the set-up and functioning of power plant components and systems

� the operation and maintenance.

Erection & Commissioning Manuals - TE

Compilation of requirements for the :

� Civil engineering

� Initial erection and

� Initial commissioning of power plants or power plant components.

The manuals are prepared for the customer according to Siemens Energy scope of supply and services, where appropriate, including the documents from contractors.

Overall documentation structure

Site Documentation – TS

The site documentation comprises :

� the proofs

� Protocols

� Certificates

� Etc.

arising during initial erection and initial commissioning in the form of quality records.

The structuring characteristics are the same as those for the operating & maintenance manuals.
