32、 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. To this end and in addition to other activities, IEC publishes International Standards,

33、 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 National Committee interested in the subject dealt with may participate in this preparator

34、y 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 (ISO) in accordance with conditions determined by agreement between the two organization

35、s. 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 representation from all interested IEC National Committees. 3) IEC Publications have the form of reco

36、mmendations 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 be held responsible for the way in which they are used or for any misinterpretation by a

37、ny 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. Any divergence between any IEC Publication and the corresponding national or regional pu

38、blication 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 to IEC marks of conformity. IEC is not responsible for any services carried out by inde

39、pendent 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 individual experts and members of its technical committees and IEC National Committees for any

40、 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 Normativ

41、e 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 responsib

42、le for identifying any or all such patent rights. International Standard IEC 62253 has been prepared by IEC technical committee 82: Solar photovoltaic energy systems. The text of this standard is based on the following documents: FDIS Report on voting 82/647/FDIS 82/656/RVD Full information on the v

43、oting for the approval of this standard 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. 62253 IEC:2011 5 The committee has decided that the contents of this publication will remain unchanged until

44、 the stability 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 reconfirmed, withdrawn, replaced by a revised edition, or amended. IMPORTANT The colour inside logo on the cover page of this publica

45、tion indicates that it contains colours which are considered to be useful for the correct understanding of its contents. Users should therefore print this document using a colour printer. 6 62253 IEC:2011 PHOTOVOLTAIC PUMPING SYSTEMS DESIGN QUALIFICATION AND PERFORMANCE MEASUREMENTS 1 Scope and obje

46、ct This International Standard defines the requirements for design, qualification and performance measurements of photovoltaic pumping systems in stand-alone operation. The outlined measurements are applicable for either indoor tests with PV generator simulator or outdoor tests using a real PV gener

47、ator. This standard applies to systems with motor pump sets connected to the PV generator directly or via a converter (DC to DC or DC to AC). It does not apply to systems with electrical storage unless this storage is only used for the pump start up (70 C), aging and dirt on the surface. 6.7 Recordi

48、ng of the measured parameters In all cases a laboratory logbook should be kept, in which all original measured quantities are recorded. As shown in Figure 1 (point D), different measured parameters are appropriate to different system configurations. In addition, different laboratories will have diff

49、erent measurement capabilities. It is therefore proposed that for each system configuration (A to D) there shall be defined a set of core-measured parameters and a set of optional measured parameters. The core parameters are straightforward to measure, requiring only basic equipment, and are the minimum data set needed to characterise the system. It is expected that all participating laboratories will measure all the core parameters. The optional parameters may require more sophisticated measureme
