18、RD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the elect

19、rical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to tech

20、nical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non- governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Orga

21、nization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technica

22、l committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publicat

23、ions is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their nationa

24、l and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment servic

25、es and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servan

26、ts or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication

27、, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility t

28、hat some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. The main task of IEC technical committees is to prepare International Standards. In exceptional circumstances, a technical committee

29、may propose the publication of a technical specification when the required support cannot be obtained for the publication of an International Standard, despite repeated efforts, or the subject is still under technical development or where, for any other reason, there is the future but no immediate p

30、ossibility of an agreement on an International Standard. Technical specifications are subject to review within three years of publication to decide whether they can be transformed into International Standards. IEC 62257-6, which is a technical specification, has been prepared by IEC technical commit

31、tee 82: Solar photovoltaic energy systems. 4 IEC TS 62257-6:2015 IEC 2015 This second edition cancels and replaces the first edition issued in 2005. It constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: redefine t

32、he maximum AC voltage from 500 V to 1 000 V as well as the maximum DC voltage from 750 V to 1 500 V; and removal of the limitation of the 100 kVA system size. Hence the removal of the word “small” with regard to the title and related references in this document. This technical specification is to be

33、 used in conjunction with the IEC 62257 series. The text of this technical specification is based on the following documents: Enquiry draft Report on voting 82/951/DTS 82/1002A/RVC Full information on the voting for the approval of this technical specification can be found in the report on voting in

34、dicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts in the IEC 62257 series, published under the general title Recommendations for renewable energy and hybrid systems for rural electrification, can be found on the IEC w

35、ebsite. Future standards in this series will carry the new general title as cited above. Titles of existing standards in this series will be updated at the time of the next edition. The committee has decided that the contents of this publication will remain unchanged until the stability date indicat

36、ed on the IEC website under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be transformed into an International standard, reconfirmed, withdrawn, replaced by a revised edition, or amended. A bilingual version of this publication may be iss

37、ued at a later date. IEC TS 62257-6:2015 IEC 2015 5 INTRODUCTION The IEC 62257 series intends to provide to different players involved in rural electrification projects (such as project implementers, project contractors, project supervisors, installers, etc.) documents for the setting up of renewabl

38、e energy and hybrid systems with AC voltage below 1 000 V and DC voltage below 1 500 V. These documents are recommendations: to choose the right system for the right place; to design the system; to operate and maintain the system. These documents are focused only on rural electrification concentrati

39、ng on, but not specific to, developing countries. They should not be considered as all inclusive to rural electrification. The documents try to promote the use of renewable energies in rural electrification; they do not deal with clean mechanisms developments at this time (CO 2emission, carbon credi

40、t, etc.). Further developments in this field could be introduced in future steps. This consistent set of documents is best considered as a whole with different parts corresponding to items for safety as well as sustainability of systems aiming at the lowest life cycle cost as possible. One of the ma

41、in objectives is to provide the minimum sufficient requirements, relevant to the field of application, that is: renewable energy and hybrid off-grid systems. The purpose of this technical specification is to propose a methodology to achieve the best technical and economic conditions for acceptance,

42、operation, maintenance and replacement of equipment and complete system life cycle. 6 IEC TS 62257-6:2015 IEC 2015 RECOMMENDATIONS FOR RENEWABLE ENERGY AND HYBRID SYSTEMS FOR RURAL ELECTRIFICATION Part 6: Acceptance, operation, maintenance and replacement 1 Scope This part of IEC 62257, which is a t

43、echnical specification, intends to describe the various rules to be applied for acceptance, operation, maintenance and replacement (AOMR) of decentralized rural electrification systems (DRES) which are designed to supply electric power for sites which are not connected to a large interconnected syst

44、em, or a national grid, in order to meet basic needs. The majority of these sites are: isolated dwellings; village houses; community services (public lighting, pumping, health centers, places of worship or cultural activities, administrative buildings, etc.); economic activities (workshops, micro-in

45、dustry, etc.). This technical specification proposes a methodology to achieve the best technical and economic conditions for acceptance, operation, maintenance and replacement of equipment and complete system life cycle. It does not substitute for technical manuals provided by manufacturers for each

46、 equipment. The complexity of the system and application will dictate the level of required AOMR documentation. 2 Normative reference The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the ed

47、ition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
