23、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. To this end and in addition to other activities, IEC publishe
24、s 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 National Committee interested in the subject dealt with may part
25、icipate 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 (ISO) in accordance with conditions determined by agreement b
26、etween 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 representation from all interested IEC National Committees. 3) IEC Publica
27、tions 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 be held responsible for the way in which they are used or for
28、 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. Any divergence between any IEC Publication and the correspond
29、ing 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 to IEC marks of conformity. IEC is not responsible for any s
30、ervices 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 individual experts and members of its technical committees and IEC
31、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, this IEC Publication or any other IEC Publications. 8) Attenti
32、on 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 this IEC Publication may be the subject of patent rights. IEC
33、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 of a technical specification when the required support cannot
34、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 an International Standard. Technical specifications are subj
35、ect to review within three years of publication to decide whether they can be transformed into International Standards. IEC TS 62600-101, which is a technical specification, has been prepared by IEC technical committee 114: Marine energy Wave, tidal and other water current converters. PD IEC/TS 6260
36、0-101:2015 6 IEC TS 62600-101:2015 IEC 2015 The text of this technical specification is based on the following documents: Enquiry draft Report on voting 114/145/DTS 114/154A/RVC Full information on the voting for the approval of this technical specification can be found in the report on voting indic
37、ated in the above table. A list of all parts in the IEC 62600 series, published under the general title Marine energy Wave, tidal and other water current converters, can be found on the IEC website. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. The committee ha
38、s decided that the contents of this publication will remain unchanged until 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 transformed into an International standard, reconfirmed, w
39、ithdrawn, 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 for the correct understanding of its
40、 contents. Users should therefore print this document using a colour printer. PD IEC/TS 62600-101:2015IEC TS 62600-101:2015 IEC 2015 7 INTRODUCTION This Technical Specification provides a uniform methodology that will ensure consistency and accuracy in the estimation, measurement, and analysis of th
41、e wave energy resource at sites that could be suitable for the installation of Wave Energy Converters (WECs), together with defining a standardised methodology with which this resource can be described. The wave energy resource is primarily defined using hydrodynamic models that are successfully val
42、idated against measured data. This Technical Specification deals directly with the theoretical resource and the main focus of the defined methodology is to generate the resource information required to estimate energy production. Practical energy production can then be estimated in conjunction with
43、other Technical Specifications in this series (IEC TS 62600), and by considering available technology and external constraints. This Technical Specification provides guidance relating to the measurement, modelling, analysis and reporting of the wave energy resource, and the linkages between these ac
44、tivities. A framework for estimating the uncertainty of the wave energy resource estimates is also provided. Application by all parties of the methodologies recommended in this document will ensure that continuing resource assessment of potential development sites is undertaken in a consistent and a
45、ccurate manner. This Technical Specification presents techniques that are expected to provide fair and suitably accurate results that can be replicated by others. The development of the wave power industry is at an early stage and the significance of particular wave energy resource characteristics i
46、s poorly understood. 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 Wave Energy Converters develops. This Technical Specification, when used in conjunction with other Technical Specification
47、s 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 developers performance of device Utilities/investors reliability/predictability of supply, return on investment, Policy-makers/P
48、lanners usage of seascape, optimisation of resource, power supply issues Consultants to produce resource data/due diligence compatible/readable data format The report required by this Technical Specification is highly technical and may be difficult to understand for some intended users. It is recomm
49、ended that a short (2 to 4 pages) summary of the key findings of the resource assessment is also produced, converting some of the more technical language into information that could be readily understood by a non-technical user.
