12、al 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 and electronic

13、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 committees; any

14、 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 Organization for Standardi

15、zation (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 committee has repres

16、entation 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 is accurate, IEC

17、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 regional publica

18、tions. 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 conformity assessment services and, in some areas,

19、 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 directors, employees, servants or agents including

20、 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 for costs (including legal fees) and expenses arising out of the publication, use of, or reliance

21、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 correct application of this publication. 9) Attention is drawn to the possibility that some of the elemen

22、ts 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 circumstances, a technical committee may propose the public

23、ation 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 future but no immediate possibility of an agree

24、ment 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, which is a technical specification, has been prepared by IEC technical committee 114: Marine energy

25、 Wave, tidal and other water current converters. DD IEC/TS 62600-1:2011 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/RVC Full information on the voting for the approval of this technical specif

The wave, tidal and water current energy industry has recently experienced a period of

29、 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 of programs, projects, and future standards. This Tech

30、nical 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 documents as far as possible. DD IEC/TS 62600-1:2011 6 TS 6260

31、0-1 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 marine renewable energy are taken to

32、 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 Specification. This Technical Specificat

33、ion 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 definitions apply. 2.1 added m

34、ass 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 In a viscous (real) fluid, the a

35、dded 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 for time domain modelling of wave

36、-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 oscillating system, the object of amp

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

38、ng 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 (marine ener

39、gy) 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 converter

40、 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, assuming that

41、 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 equates to: MT

42、BF/(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 by the h

43、ydrodynamically 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 of the flo

44、ating 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.

45、.14 conversion 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

46、 as wave-to-wire 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

47、2.16 deep water (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 LdTL2tanh22g=where L is the wave length; d is the water

48、depth; T is the period; g is the gravitation acceleration. In deep water, the dispersion equation may be simplified to 2256,12TTL =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 linear and

49、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.
