Guide for procurement of power station equipment -- Part 2-5: Electrical equipment - Motors

This standard gives guidance on writing the technical specification for the procurement of motors for use in electricity generating stations (power stations). This Guide for procurement is not applicable to equipment for use in the nuclear reactor plant area of nuclear power stations. Other possible applications of such equipment have not been considered in the preparation of this Guide.
This Guide covers motors within installations primarily concerned with the generation of electrical power. However, as a complete electrical drive system is not defined in this Guide, attention is drawn to the possible additional electrical and mechanical stresses to which the motor may be subjected e.g. by a static AC converter/inverter.  Reference should be made to IEC 60034-17.
The equipment covered by this Guide is defined by its function rather than design type.  Therefore, the guidance to the specification is stated in performance terms rather than being specified by a detailed description of the equipment to be supplied.
This Guide indicates to potential purchasers how their specification should be prepared so that:
- the equipment type and capacity interfaces correctly with other elements of the systems;
- predicted performance is achieved;
- ancillary equipment is properly sized;
- reliability, availability and safety requirements are achieved;
- proper consideration is given to the evaluation process and the quality measures to be  applied.
This Guide does not determine the type of specification (e.g. detailed, performance, functional) or the extent of supply for any given contract which is normally decided on the basis of the purchaser’s project strategy. It does not cover:
- any commercial, contractual or legal issues which are normally in separate parts of an enquiry;
- any allocation of responsibilities which are determined by the contract.
This Guide does not prescribe the arrangement of the documents in the enquiry.

EN 45510 is theresponsibility of JTFPE. The so called “common clauses”, as appropriate, also appear in italics in thedocuments specific to particular equipment.In this Guide, words in bold type indicate that they have the meaning given in the definitions, clause 3.In this Guide, words and sentences not in italics are specific to this Guide and refer to the particularequipment covered.SIST EN 45510-2-5:2003

The enquiry should define allorganisational interfaces and the procedures to be employed for managing the contract and the site.4.2Site locationThe specification should describe the geographical location of the site which may include surveyingpoints, the previous use of the site and any local features such as impact of industrial or military activitiesand planning restrictions.Where applicable, the specification should indicate site datum on specification drawings and specifysite and drawing orientation and define co-ordinate axes (x,y,z) and numbering order to ensureconsistency between suppliers of connected equipment.Where appropriate, the specification should define the permitted ground loading, dimensional and timerestrictions on access routes up to but not including public roads or railways.The specification should identify, where appropriate, the environment of the site in which theequipment will operate. The following factors may normally be included if appropriate:-climatic e.g. atmospheric pressure, annual variation of air and cooling water temperature, relativehumidity, rain fall, icing, snow, wind velocity (normal and maximum), lightning;SIST EN 45510-2-5:2003

EN 45510-2-5:2002- 10 --geological e.g. seismic conditions and characteristics of subsoil (e.g. caverns, gliding stratifications,load bearing capability of subsoils);-geographic e.g. elevation, influence of local topography and structures;-hydrological e.g. flooding and tides.4.3Equipment taskThe specification should describe in general terms the function, task or role of the equipment to bepurchased. e.g. whether it is part of a new power generating

plant, a modification to an existing powergenerating plant or replacement equipment.Where appropriate, the specification should define the function and the known limitations, if any, in theequipment connected to that which is being supplied so that the equipment may avoid imposingadverse conditions or the supplier may suggest modifications to connected equipment which wouldensure satisfactory operation.4.4Equipment to be purchasedThe specification may define the equipment type or arrangement to be purchased.For example, the purchaser may specify: synchronous or asynchronous (induction) motor.The specification may state any preferences with regard to the extent of the supply.

For example, thePurchaser may wish to include an integral or separate bearing lubricating system.The specification may state requirements for the type of enclosure selected, particularly if the motor isto be installed in a hazardous area.The specification may also define preferences for equipment types (or give information) regardingcompatibility with existing equipment, if required.The specification should define the intended methods or local practice for maintenance, inspection andoperation.The specification should define requirements with regard to the general appearance of the equipment(e.g. dimensions, shape or colour) to meet local planning requirements or specific criteria, where suchrequirements exist.NOTE

Attention is drawn to European, national and/or local legislation which may place restrictions in this area.4.5Control and instrumentationThe specification should define the general requirements for the control and instrumentation system, thelevel of operator intervention allowed or required, integration with other control systems, localised controlloops, commonality and redundancy.NOTE

Guidance on the procurement of control and instrumentation systems for power stations, including advice on interfaces, can befound in EN 45510-8-1.4.6 Electrical supplies and other servicesThe specification should define the electrical supplies available for the operation of the equipment, theirvoltages and frequencies, with their range of variation, phases available and, where appropriate, theacceptable values of maximum load (kW) and short circuit level at each voltage level and the harmoniccontent. Requirements for terminals and terminal boxes should be stated; these should be to arecognised European or international standard.SIST EN 45510-2-5:2003

- 11 -EN 45510-2-5:2002The specification should define the type and capacity of other services for the operation of theequipment such as service fluids.4.7 Other interfacesThe specification should define the interfaces with existing ancillary or new ancillary equipment to besupplied under separate contracts which interact directly with the equipment.For example, protection, metering, cabling, auxiliary electrical systems, civil works, cranage, ortemporary systems.4.8Project programmeThe specification should describe the overall programme and timescale in which the project is to becarried out.

This may include the principal dates associated with tendering, placement of orders, accessto site, start and completion of installation, commissioning, take-over and final acceptance.4.9Equipment identification systemsThe specification may
