12、RGY WAVE, TIDAL AND OTHER WATER CURRENT CONVERTERS Part 1: Terminology 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 intern

13、ational 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, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter

14、 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 preparatory work. International, governmental and non- governmental organizations liaising with the IEC also particip

15、ate in this preparation. IEC collaborates closely with 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 in

16、ternational 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 recommendations for international use and are accepted by IEC National Committees in that sense. While all rea

17、sonable 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 any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply I

18、EC 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 publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conf

19、ormity. 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 independent certification bodies. 6) All users should ensure that they have the latest edition of this publica

20、tion. 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 personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or

21、 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 Normative references cited in this publication. Use of the referenced publications is indispensable for the correc

22、t 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 responsible for identifying any or all such patent rights. The main task of IEC technical committees is to prepare

23、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 publication of an International Standard, despite repeated efforts, or the subject is still under technical devel

24、opment 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 three years of publication to decide whether they can be transformed into International Standards. IEC 62600-1,

25、which is a technical specification, has been prepared by IEC technical committee 114: Marine energy Wave, tidal and other water current converters. 4 TS 62600-1 IEC:2011(E) The text of this technical specification is based on the following documents: Enquiry draft Report on voting 114/65/DTS 114/76/

26、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. The committee has decided that the contents of this publication

27、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, withdrawn, replaced by a revised edition, or amen

28、ded. A bilingual version of this publication may be issued at a later date. TS 62600-1 IEC:2011(E) 5 INTRODUCTION This Technical Specification has been developed as a tool for the international marine energy community, to assist in creating clarity and understanding. The wave, tidal and water curren

29、t energy industry has recently experienced a period of rapid growth and sector development. With this expansion, it became apparent that a glossary of terms for the sector was required. The aim of this Technical Specification is to present clear and consistent language that will aid the development

30、of programs, projects, and future standards. This Technical Specification lists the terms that the marine energy industry commonly uses. It is an evolving document that will change as new terms and symbols are added. The terminologies herein have been harmonized with IEC 60050 and other IEC document

31、s as far as possible. 6 TS 62600-1 IEC:2011(E) MARINE ENERGY WAVE, TIDAL AND OTHER WATER CURRENT CONVERTERS Part 1: Terminology 1 Scope This part of IEC 62600 defines the terms relevant to ocean and marine renewable energy. For the purposes of this Technical Specification, sources of ocean and marin

32、e renewable energy are taken to include wave, tidal current, and other water current energy converters. Terms relating to conventional dam and tidal barrage, offshore wind, marine biomass, ocean thermal and salinity gradient energy conversion are not included in the scope of this Technical Specifica

33、tion. This Technical Specification is intended to provide uniform terminology to facilitate communication between organizations and individuals in the marine renewable energy industry and those who interact with them. 2 Terms and definitions For the purposes of this document, the following terms and

34、 definitions apply. 2.1 added mass extra mass associated with the additional force necessary to accelerate a body through a fluid compared to the same acceleration in a vacuum NOTE 1 In general, added mass is a variable that depends on the state of the unsteady motion and is not a constant. NOTE 2 I

35、n a viscous (real) fluid, the added mass would include kinetic energy of a fluid layer entrained by the accelerating body. 2.2 added mass at infinity limit of the mass corresponding to the added mass as the frequency tends to infinity NOTE The value of added mass at infinity is normally necessary fo

36、r time domain modelling of wave-body interaction. 2.3 added mass coefficient ratio between added mass and the mass of the water displaced by the submerged body 2.4 amplitude control method to obtain the optimum oscillatory motion amplitude to capture a maximum of wave energy NOTE For a simple oscill

37、ating system, the object of amplitude control is to obtain a given oscillatory velocity amplitude that should be related with the wave excitation force. TS 62600-1 IEC:2011(E) 7 2.5 annual energy production (marine energy converter) estimate of total energy production of a marine energy converter sy

38、stem during a one-year period obtained by applying its power performance assessment to a prospective marine energy resource characterization and assuming 100 % availability NOTE Actual annual energy production is unlikely to exceed this estimate. IEC 60050-415:1999, 415-05-09, modified 2.6 array (ma

39、rine energy) farm of marine energy converters arranged specifically so as to enhance energy capture NOTE Array spacing is dictated by hydrodynamic considerations and may be very closely packed so as to constitute a single platform or an arrangement of identical devices. 2.7 attenuator device energy

40、converter which is aligned parallel to the predominant direction of wave incidence 2.8 availability (marine energy converter) ability of a marine energy conversion system to be in a state to perform a necessary function under given conditions at a given instant of time or over a given duration, assu

41、ming that the necessary external resources are provided NOTE 1 For continuously running equipment availability equates to: uptime/(uptime + downtime). NOTE 2 Where reliability is specified in Mean Time Between Failures (MTBF) and maintainability in Mean Time To Repair (MTTR), availability also equat

42、es to: MTBF/(MTBF + MTTR). IEC 60050-191:1990, 191-02-05, modified 2.9 capture area (tidal) equal to the power captured by the hydrodynamically functional part of a TEC divided by power per square metre of the incident tidal stream 2.10 capture length (wave) capture width equal to the power captured

43、 by the hydrodynamically functional part of a WEC divided by power per metre of the incident wave field 2.11 centre of buoyancy centroid of the submerged volume 2.12 centre of flotation point coinciding with the centroid of the water-plane area NOTE The water-plane area is the cross-sectional area o

44、f the floating body at mean water level in calm water. 2.13 chart datum reference level of water, typically from a selected phase of the tide at a specific location NOTE Different hydrographic organizations have differing conventions for defining chart datum. 8 TS 62600-1 IEC:2011(E) 2.14 conversion

45、 efficiency (resource to wire) measure of the overall effectiveness of a marine energy converter calculated as the ratio of electrical power output in relation to the incident power in the water resource NOTE 1 For WECs, conversion efficiency (resource to wire) is sometimes referred to as wave-to-wi

46、re conversion efficiency. NOTE 2 Conversion efficiency (resource to wire) is normally calculated over extended periods (e.g. tidal cycle, years, etc.). 2.15 current profile variation in velocity throughout the water column, typically displayed as a function of height above the sea bed 2.16 deep wate

47、r (offshore) spatial location where the depth of the water is greater than or equal to half the wave length NOTE The deep water (offshore) spatial location is based on the kinematic properties of waves. The dispersion equation is L d T L 2 tanh 2 2 g =where L is the wave length; d is the water depth

48、; T is the period; g is the gravitation acceleration. In deep water, the dispersion equation may be simplified to 2 2 56 , 1 2 T T L = = g2.17 degree of freedom independent displacements and/or rotations that specify the orientation of a body or system NOTE 1 A marine body may experience three linea

49、r and three rotational motions as depicted in Figures 1 and 2. NOTE 2 The principal axis is parallel to the mean water surface and aligned with the direction of incident energy, and the rotations act about the centre of gravity.
