21、red assessment data FOREWORD 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 st

22、andardization in the electrical 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 prepar

23、ation is entrusted to technical 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 wi

24、th the International Organization 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 sub

25、jects since each technical 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 technica

26、l content of IEC Publications 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

27、possible in their national 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 con

28、formity assessment services 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 dir

Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is d

31、rawn to the possibility that 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 circumstance

32、s, a technical committee 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

33、future but no immediate possibility 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 TS 62600-102, which is a technical specification, has been pr

34、epared by IEC technical committee 114: Marine energy Wave, tidal and other water current converters. PD IEC/TS 62600-102:2016IEC TS 62600-102:2016 IEC 2016 5 The text of this technical specification is based on the following documents: Enquiry draft Report on voting 114/179/DTS 114/187A/RVC Full inf

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 speci

PD IEC/TS 62600-102:2016 6 IEC TS 62600-102:2016 IEC 2016 INTRODUCTION This technical specification, IEC TS 6

39、2600-102, provides a uniform methodology for estimating and reporting the performance of a Wave Energy Converter (WEC) at a prospective new deployment location. The performance estimation methodology is based primarily on observations and measurement results gathered during field deployment of the W

40、EC at a primary location (as per IEC TS 62600-100) with different metocean conditions compared to the prospective new location. Further, it is possible that the WEC design will incorporate changes to accommodate the new site conditions. To assess the performance, inclusion of additional information

41、based on validated numerical and physical models is specified. In this technical specification the completed field deployment location is referred to as “Location 1” and the prospective deployment location is referred to as “Location 2.” The specification provides a methodology for arriving at the m

42、ean annual energy production (MAEP) for the WEC at Location 2. Other Technical Specifications in this series (IEC TS 62600) are drawn upon to provide the wave resource and WEC performance information needed to enable this analysis. The methodology involves: assessment of the wave resource at Locatio

43、n 1 and Location 2, characterization of the WEC performance at Location 1, assessment and compensation for the impact of discrepancies in the metocean conditions between Location 1 and Location 2 on the WEC performance characterization, assessment of the impact of changes to the WEC configuration be

44、tween Location 1 and Location 2 on the WEC performance characterization, complementing the performance observations from Location 1 with fit, experimental or numerically modelled data, estimating the MAEP based on the composite performance characterization of the WEC. This technical specification pr

45、ovides: a) guidance on the use of observations from Location 1, b) methods for assessing and reporting the validity of numerical and physical models, c) limits on the permissible changes to the WEC between Locations 1 and 2, d) limits on the use of data fitting techniques, and e) requirements for re

46、porting. The wave power industry is at an early stage of development. There is little practical experience with field-scale WECs deployment. Because of this, the present document is designated as a technical specification and will be subject to change as more data is collected and experience with wa

47、ve energy converters develops. This Technical Specification, when used in conjunction with other Technical Specifications in this series (IEC TS 62600), is intended for several types of users, including, but not limited to, the following: Project developers income, return on investment Device develo
