28、monitoring and control of wind power plants Logical node classes and data classes for condition monitoring FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). Th

29、e 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 publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specif

30、ications (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 participate in this preparatory work. International, governmental and non- governmental organizations

31、 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 between the two organizations. 2) The formal decisions or agreements of IEC on technical matters e

32、xpress, 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 Publications have the form of recommendations for international use and are accepted by IEC National Com

33、mittees 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 any misinterpretation by any end user. 4) In order to promote international uniformity, IEC Nati

34、onal 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 corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does

35、 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 services carried out by independent certification bodies. 6) All users should ensure that they hav

36、e 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 National Committees for any personal injury, property damage or other damage of any nature whatso

37、ever, 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) Attention is drawn to the Normative references cited in this publication. Use of the referenced publicat

38、ions 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 shall not be held responsible for identifying any or all such patent rights. International Standa

39、rd IEC 61400-25-6 has been prepared by IEC technical committee 88: Wind energy generation systems. This second edition cancels and replaces the first edition published in 2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respe

40、ct to the previous edition: a) Major restructuring of the datamodel to accommodate needed flexibility. b) UFF58 format is no longer used. c) Access to data is now using the standard reporting and logging functions. d) Recommendations for creating datanames to accommodate needed flexibility have been

41、 defined. 6 IEC 61400-25-6:2016 IEC 2016 The text of this standard is based on the following documents: FDIS Report on voting 88/606/FDIS 88/611/RVD 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

42、document has been drafted in accordance with the ISO/IEC Directives, Part 2. As the title of technical committee 88 was changed in 2015 from Wind turbines to Wind energy generation systems a list of all parts of the IEC 61400 series, under the general title Wind turbines and Wind energy generation s

43、ystems can be found on the IEC website. The committee has decided that the contents of this document will remain unchanged until the stability date indicated on the IEC website under “http:/webstore.iec.ch“ in the data related to the specific document. At this date, the document will be reconfirmed,

44、 withdrawn, replaced by a revised edition, or amended. A bilingual version of this publication may be issued at a later date.

IEC 61400-25-6:2016 IEC 2016 7 INTRODUCTION The IEC 61400-25 series defines information models and information exchange models for monitoring and control of wind power plants. The modelling approach (for information mode

46、ls and information exchange models) of IEC 61400-25-2 and IEC 61400-25-3 uses abstract definitions of classes and services such that the specifications are independent of specific communication protocol stacks, implementations, and operating systems. The mapping of these abstract definitions to spec

47、ific communication profiles is defined in IEC 61400-25-4 1 . This document defines an information model for condition monitoring information and explains how to use the existing definitions of IEC 61400-25-2 as well as the required extensions in order to describe and exchange information related to

48、condition monitoring of wind turbines. The models of condition monitoring information defined in this document may represent information provided by sensors or by calculation. In the context of this document, condition monitoring means a process with the purpose of observing components or structures

49、 of a wind turbine or wind power plant for a period of time in order to evaluate the state of the components or structures and any changes to it, in order to detect early indications of impending failures. With the objective to be able to monitor components and structures recorded under approximately the same conditions, this document introduces the operational state bin concept. The operational state bin concept is mult
