14、trotechnical 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 electrical and electronic fields.

15、 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 technical committees; any IEC Na

16、tional 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 Organization for Standardization

17、(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 technical committee has representatio

18、n 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 Publications is accurate, IEC cannot

19、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 national and regional publications.

20、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 services and, in some areas, access

21、 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, servants or agents including indivi

22、dual 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, use of, or reliance upon, t

23、his 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 that some of the elements of t

24、his 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 may propose the publication o

25、f 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 possibility of an agreement on

26、 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 62257-1, which is a technical specification, has been prepared by IEC technical committee 82: Solar photovoltaic en

27、ergy systems. It was developed in cooperation with other IEC technical committees and subcommittees dealing with renewable energies and related matters, namely IEC technical committee 21 (Secondary cells and batteries), subcommittee PD IEC/TS 62257-1:2015 4 IEC TS 62257-1:2015 IEC 2015 21A (Secondar

28、y cells and batteries containing alkaline or other non-acid electrolytes), IEC technical committee 64 (Electrical installations and protection against electric shock), IEC technical committee 88 (Wind turbines). This third edition cancels and replaces the second edition issued in 2013. It constitute

29、s a technical revision. The main technical changes with regard to the previous edition are as follows: Redefine the maximum AC voltage from 500 Va.c. to 1 000 Va.c., the maximum DC voltage from 750 Vd.c. to 1 500 Vd.c. and removal of the limitation of 100 kVA system size. Hence the removal of the wo

30、rd “small” in the title and related references in this technical specification. This technical specification shall be used in conjunction with the other documents of the IEC 62257 series. The text of this technical specification is based on the following documents: Enquiry draft Report on voting 82/

31、942/DTS 82/979/RVC Full information on the voting for the approval of this technical specification can be found in the report on voting indicated 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, publ

32、ished under the general title Recommendations for renewable energy and hybrid systems for rural electrification, can be found on the IEC website. 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 o

33、f the next edition. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated 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 Int

34、ernational standard, reconfirmed, withdrawn, replaced by a revised edition, or amended. A bilingual version of this publication may be issued at a later date. IMPORTANT The colour inside logo on the cover page of this publication indicates that it contains colours which are considered to be useful f

36、ogether with access to clean water, improved healthcare, education, personal advancement and economic development. Several strategies can be adopted to implement rural electrification. Rural electrification can be completed through connection to a national or regional electrification grid. The IEC 6

37、2257 series applies to cases where the grid is too far away (too costly) or the individual demand centres are too small to make grid access economic, where autonomous power systems may be used to supply these services. This series IEC 62257 provides technical specifications to different players invo

38、lved in rural electrification projects (such as project developers, project implementers, installers, etc.) for the setting up of renewable energy and hybrid systems with AC voltage below 1 000 Vac and DC voltage below 1 500 Vdc. These specifications are recommendations: a) to choose the right syste

39、m for the right place, b) to design the system, c) to operate and maintain the system. The specifications focus on rural electrification concentrating on, but not specific to, developing countries. They must not be considered as all inclusive to rural electrification. That means that they could be u

40、sed for rural electrification or electrification of remote sites in developed countries also. They try to promote the use of renewable energies in rural areas, but they do not deal with clean mechanisms development at this time (CO2emission, carbon credit, etc.) Further developments in this field co

41、uld be introduced in future steps. This consistent set of documents is best considered as a whole with different parts corresponding to items for safety, sustainability of systems and at the lowest life cycle cost as possible. One of the main objectives is to provide the minimum sufficient requireme

42、nts, relevant to the field of application, that is: renewable energy and hybrid off-grid systems.

43、fication 1 Scope This part of IEC 62257 first introduces a methodology for implementing rural electrification using autonomous hybrid renewable energy systems. Secondly, it provides a guide for facilitating the reading and the use of the IEC 62257 series for setting up decentralized rural electrific

44、ation in developing countries or in developed countries, the only difference being the level of quality of service and the needed quantity of energy that the customer can afford. The IEC 62257 series is designed as follows: Parts 2 to 6 are methodological supports for the management and implementati

45、on of projects. Parts 7 to 12 are technical specifications for individual or collective systems and associated components. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
