20、 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 electrical

21、 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 technical

22、 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 Organizat

23、ion 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 technical com

24、mittee 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 Publications

25、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 national and

26、 regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in con

27、formity with an IEC Publication. 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 individual experts and members of its technical committees and IEC National Committees for

28、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, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Norma

29、tive 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 this IEC Publication may be the subject of patent rights. IEC shall not be held respon

30、sible 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 of a technical specification when the required support cannot be obtained for the publ

31、ication 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 an International Standard. Technical specifications are subject to review within thr

32、ee years of publication to decide whether they can be transformed into International Standards. IEC 62257-9-6, which is a technical specification, has been prepared by IEC technical committee 82: Solar photovoltaic energy systems. ARP 062-9-6:2009This standard may only be used and printed by approve

33、d subscription and freemailing clients of the SABS.TS 62257-9-6 IEC:2008(E) 5 This document is based on IEC/PAS 62111 (1999); it cancels and replaces the relevant parts of IEC/PAS 62111. This part of IEC 62257 is to be used in conjunction with the IEC 62257 series. The text of this technical specifi

34、cation is based on the following documents: Enquiry draft Report on voting 82/510/DTS 82/532/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

35、 ISO/IEC Directives, Part 2. A list of all parts of IEC 62257 series, under the general title: Recommendations for small renewable energy and hybrid systems for rural electrification, can be found on the IEC website. The committee has decided that the contents of this publication will remain unchang

36、ed until the maintenance result date indicated on the IEC web site 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 bil

37、ingual version of this publication may be issued at a later date. ARP 062-9-6:2009This standard may only be used and printed by approved subscription and freemailing clients of the SABS. 6 TS 62257-9-6 IEC:2008(E) INTRODUCTION The IEC 62257 series of documents intends to provide to different players

38、 involved in rural electrification projects (such as project implementers, project contractors, project supervisors, installers, etc.) documents for the setting up of renewable energy and hybrid systems with a.c. voltage below 500 V, d.c. voltage below 750 V and power below 100 kVA. These documents

39、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 concentrating on but not specific to developing countries. They must not be considered as all inclusive to rural el

40、ectrification. 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 credit, etc.). Further developments in this field could be introduced in future steps. This consistent set of doc

41、uments 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 requirements, relevant to the field of application that is: small rene

42、wable energy and hybrid off-grid systems. This document and the others of the IEC 62257 series are only guidance and so cannot be International Standards. Additionally their subject is still under technical development and so they shall be published as Technical Specifications. ARP 062-9-6:2009This

43、standard may only be used and printed by approved subscription and freemailing clients of the SABS.TS 62257-9-6 IEC:2008(E) 7 RECOMMENDATIONS FOR SMALL RENEWABLE ENERGY AND HYBRID SYSTEMS FOR RURAL ELECTRIFICATION Part 9-6: Integrated system Selection of Photovoltaic Individual Electrification Syste

44、ms (PV-IES) 1 Scope The purpose of this part of IEC 62257 is to propose simple selection procedure and cheap, comparative tests which can be performed in laboratories of developing countries, in order to identify the most suitable model of small Photovoltaic Individual Electrification Systems (PV- I

45、ES) up to 500 Wp for a particular rural electrification project from a number of products submitted for test. It is different of the scope of IEC 62124, Photovoltaic (PV) stand alone systems Design verification, which provides guidance for verifying the design of stand-alone PV systems and indoor an

46、d outdoor tests in order to evaluate the performance of PV systems including PV generator, battery storage and loads such as lights, TV sets, and refrigerators. The tests provided in IEC 62257-9-6 allow assessment of the performance of a PV-IES according to the requirement of the General Specificati

47、on (GS) of the project (see IEC/TS 62257-2) and to verify their ability to provide the required service. They should be performed locally, as close as possible to the real site operating conditions. This document is not a type approval standard. It is a technical specification to be used as guidelin

48、es and does not replace any existing IEC standard on PV systems. 2 Normative references The following referenced documents are indispensable for the application of this document.
