20、EC 2017 INTERNATIONAL ELECTROTECHNICAL COMMISSION _ WIND TURBINES ENERGY GENERATION SYSTEMS Part 25-1: Communications for monitoring and control of wind power plants Overall description of principles and models FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organizati

21、on 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 fields. To this end and in addition to other activities, IEC p

22、ublishes 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 m

23、ay 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 Standardization (ISO) in accordance with conditions determined by agre

24、ement 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 representation from all interested IEC National Committees. 3) IEC

25、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 cannot be held responsible for the way in which they are used

26、 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 publications. Any divergence between any IEC Publication and the cor

27、responding 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 fo

28、r 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 individual experts and members of its technical committees a

29、nd 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 upon, this IEC Publication or any other IEC Publications. 8)

30、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 elements of this IEC Publication may be the subject of patent right

31、s. IEC shall not be held responsible for identifying any or all such patent rights. DISCLAIMER This Redline version is not an official IEC Standard and is intended only to provide the user with an indication of what changes have been made to the previous version. Only the current version of the stan

32、dard is to be considered the official document. This Redline version provides you with a quick and easy way to compare all the changes between this standard and its previous edition.

This second edition cancels and replaces the first edition published in 2006. This edition constitutes a technical revision

34、. This edition includes the following significant technical changes with respect to the previous edition: a) general harmonization of text and overview models with the other parts of the IEC 61400-25 series, b) harmonization of definitions in other related standards. The text of this International S

35、tandard is based on the following documents: CDV Report on voting 88/587/CDV 88/622/RVC Full information on the voting for the approval of this International Standard can be found in the report on voting indicated in the above table. This document has been drafted in accordance with the ISO/IEC Dire

36、ctives, Part 2. The title of TC 88 was changed in 2015 from Wind turbines to Wind energy generation systems. A list of all parts in the IEC 61400 series, published under the general titles Wind turbines and Wind energy generation systems can be found on the IEC website. The users of IEC 61400-25 hav

37、e formed a community, USE61400-25. For further information see http:/www.use61400-. Attached to the release of the IEC 61400-25 standard series and in addition to the standard IEC maintenance process, a specific maintenance process is set up to handle technical issues raised after publication. Here

38、are the main principles: Technical issues (called TISSUES) are collected from the release of the new document in cooperation with the user group for the IEC 61400-25 standard series USE61400-25. The collected TISSUES can be categorized in two groups: TISSUES that can threaten interoperability betwee

39、n implementations of the standard and that need either corrections or clarifications (“IntOp” TISSUES), TISSUES that propose new features that will be implemented in future versions of the standard (“next edition” TISSUES). IntOp TISSUES require immediate clarification and are following a transparen

40、t fixing process handled by the user group for the IEC 61400-25 standard series together with the editors of the IEC 61400-25 standard series. The detailed specification of this process, the list of TISSUES, associated fix, their status and impact on implementation and certification are accessible t

41、hrough the USE61400-25 web site http:/www.use61400-. IEC recommends implementing the proposed fixes to IntOp TISSUES, as soon as they have reached the “green” status. The list of TISSUES which are implemented in an intelligent electronic device (IED) should be transparently stated by its manufacture

IEC 61400-25-1:2017 RLV IEC 2017 7 INTRODUCTION IEC 61400-25 (all parts) addresses is intended for vendors (manufacturers, suppliers), operators, owners, planners, and designers of wind power plants as well as system integrators and utility companies operating in the wind energy market. IEC 6

45、1400-25 (all parts) is intended to be accepted and to be used world-wide as the international standard for communications in the domain of wind power plants. IEC 61400-25 (all parts) has been developed in order to provide a uniform communications basis for the monitoring and control of wind power pl

46、ants. It defines wind power plant specific information, the mechanisms for information exchange and the mapping to communication protocols. In this regard, IEC 61400-25 (all parts) defines details required to exchange the available information with wind power plant components in a manufacturer-indep

47、endent environment. This is done by definitions made in this part of IEC 61400-25 or by reference to other standards. The wind power plant specific information describes the crucial and common process and configuration information. The information is hierarchically structured and covers for example

48、common information found in the rotor, generator, converter, grid connection and the like. The information may be simple data (including timestamp and quality) and configuration values or more comprehensive attributes and descriptive information, for example engineering unit, scale, description, ref

49、erence, statistical or historical information. All information of a wind power plant defined in IEC 61400-25 (all parts) is name tagged. A concise meaning of each data is given. The standardized wind power plant information can be extended by means of a name space extension rule. All data, attributes and descriptive information can be exchanged by corresponding services. The implementation of IEC 61400-25 (all parts) allows SCADA systems (supervis
