This Guide for procurement has been prepared by the CEN/CENELEC Joi
23、nt Task Force Power Engineering (JTFPE) of which the Secretariat is held by the British Standards Institution. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by September 2000, and conflicting natio
24、nal standards shall be withdrawn at the latest by September 2000. Annexes designated “informative“ are given for information only. In this standard, annex A is informa tive. This Guide for procurement has been prepared under mandates given to CEN and CENELEC by the European Commission and the Europe
25、an Free Trade Association. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembour
26、g, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.

34、strumentation EN 4551 O Part 1 contains those clauses common to all the above Guides giving the provisions of a non equipment specific nature for use in the procurement of power station plant. EN 4551 O is the responsibility of JTFPE. The so called “common clauses“, as appropriate, also appear in it
35、alics in the documents 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 particular equipment covered. O BSI 08-2000
36、 Page 7 EN 4551 0-2-4:2000 1 Scope This standard gives guidance on writing the technical specification for the procurement of static a.c. and d.c. high power convertors for use in electricity generating stations (power stations). This Guide for procurement is not applicable to equipment for use in t
37、he 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 each type of power convertor, .e. rectifier, inverter, static excitation system, conversion of a.c. to a.c.1d.c. to d.c.
38、 and switching, for the purpose of changing andlor controlling one or more characteristics. This type of equipment is used for many applications such as motor drives and actuators, e.g. variable frequency starting equipment, a.c. and d.c. power supplies for computers and instrumentation, in chemical
39、 process plant, e.g. rectifiers for electrolysis in hydrogen production, in mechanical plant, e.g. electrostatic precipitators, etc. For additional, or specific, requirements for batteries, battery chargers or uninterruptible power supplies (UPS) refer to the relevant guides in this series. The equi
40、pment 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 sp
41、ecification should be prepared so that - - predicted performance is achieved, - - - the equipment type and capacity interfaces correctly with other elements of the systems, ancillary equipment is properly sized, reliability, availability and safety requirements are achieved, proper consideration is
42、given to the evaluation process and the qualify measures to be applied. This Guide does not determine the type ofspecification (e.g. detailed, performance, functional) or the extent of supply for any given contract which is normally decided on the basis of thepurchasers project strategy. It does not
43、 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. NOTE: As a comprehensive European environ
44、mental policy is still under preparation, this Guide does not address the environmental implications of the equipment.
