18、(IEC) is a worldwide organization for standardization comprisingall national electrotechnical committees (IEC National Committees). The object of IEC is to promoteinternational co-operation on all questions concerning standardization in the electrical and electronic fields. Tothis end and in additio

19、n to other activities, IEC publishes International Standards, Technical Specifications,Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IECPublication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interestedin

20、 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.IEEE Standards documents are developed within IEEE Societies and Standards Coordinating Committees of theIEEE St

21、andards Association (IEEE-SA) Standards Board. IEEE develops its standards through a consensusdevelopment process, approved by the American National Standards Institute, which brings together volunteersrepresenting varied viewpoints and interests to achieve the final product. Volunteers are not nece

22、ssarilymembers of IEEE and serve without compensation. While IEEE administers the process and establishes rulesto promote fairness in the consensus development process, IEEE does not independently evaluate, test, orverify the accuracy of any of the information contained in its standards. Use of IEEE

23、 Standards documents iswholly voluntary. IEEE documents are made available for use subject to important notices and legal disclaimers(see http:/standards.ieee.org/IPR/disclaimers.html for more information).IEC collaborates closely with IEEE in accordance with conditions determined by agreement betwe

24、en the twoorganizations. This Dual Logo International Standard was jointly developed by the IEC and IEEE under theterms of that agreement.2) The formal decisions of IEC on technical matters express, as nearly as possible, an international consensus ofopinion on the relevant subjects since each techn

25、ical committee has representation from all interested IECNational Committees. The formal decisions of IEEE on technical matters, once consensus within IEEE Societiesand Standards Coordinating Committees has been reached, is determined by a balanced ballot of materiallyinterested parties who indicate

26、 interest in reviewing the proposed standard. Final approval of the IEEEstandards document is given by the IEEE Standards Association (IEEE-SA) Standards Board.3) IEC/IEEE Publications have the form of recommendations for international use and are accepted by IECNational Committees/IEEE Societies in

27、 that sense. While all reasonable efforts are made to ensure that thetechnical content of IEC/IEEE Publications is accurate, IEC or IEEE cannot be held responsible for the way inwhich they are used or for any misinterpretation by any end user.4) In order to promote international uniformity, IEC Nati

28、onal Committees undertake to apply IEC Publications(including IEC/IEEE Publications) transparently to the maximum extent possible in their national and regionalpublications. Any divergence between any IEC/IEEE Publication and the corresponding national or regionalpublication shall be clearly indicat

29、ed in the latter.5) IEC and IEEE do not provide any attestation of conformity. Independent certification bodies provide conformityassessment services and, in some areas, access to IEC marks of conformity. IEC and IEEE are not responsiblefor any services carried out by independent certification bodie

31、sand the Standards Coordinating Committees of the IEEE Standards Association (IEEE-SA) Standards Board,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

32、, or reliance upon, thisIEC/IEEE Publication or any other IEC or IEEE Publications.8) Attention is drawn to the normative references cited in this publication. Use of the referenced publications isindispensable for the correct application of this publication.9) Attention is drawn to the possibility

33、that implementation of this IEC/IEEE Publication may require use ofmaterial covered by patent rights. By publication of this standard, no position is taken with respect to theexistence or validity of any patent rights in connection therewith. IEC or IEEE shall not be held responsible foridentifying

34、Essential Patent Claims for which a license may be required, for conducting inquiries into the legalvalidity or scope of Patent Claims or determining whether any licensing terms or conditions provided inconnection with submission of a Letter of Assurance, if any, or in any licensing agreements are r

35、easonable ornon-discriminatory. Users of this standard are expressly advised that determination of the validity of any patentrights, and the risk of infringement of such rights, is entirely their own responsibility.International Standard IEC IEEE 61850-9-3 has been prepared by IEC Technical Committe

36、e 57, Power systems management and associated information exchange, in cooperation with 4 IEC/IEEE 61850-9-3:2016 IEC/IEEE 2016 IEC subcommittee 65C, Industrial networks, and with IEEE Power Systems Relaying Committee Working Group H24/Substation Committee Working Group C7, of the Power all ports in

37、 the MASTER state, in which case the BC is the grandmaster. IEC/IEEE 61850-9-3:2016 9 IEC/IEEE 2016 NOTE 1 Within a time domain, a BC has a port in the SLAVE state in the upper subdomain and one or several ports in the MASTER state in the lower subdomain(s) (see IEC TR 61850-90-4). NOTE 2 A BC filte

38、rs the messages that are forwarded from one subdomain to the other(s). A BC does not propagate event messages, but does propagate management messages. A BC propagates selected TLVs such as ALTERNATE_TIME_OFFSET_INDICATOR (ATOI) from one subdomain to the next, but these TLVs are attached to different

39、 Announce messages. 6 Protocol specifications All clocks shall transmit PTP messages according to IEC 61588:2009 IEEE Std 1588-2008, Annex F (Transport of PTP over IEEE 802.3 /Ethernet). All clocks shall support the delay measurement defined in IEC 61588:2009 IEEE Std 1588-2008, 10.3 and 11.4 (Peer

40、delay mechanism). All clocks shall support the PTP timescale defined in IEC 61588:2009 IEEE Std 1588-2008, 7.2.2 (based on TAI). All singly attached clocks shall support the default best master clock algorithm in IEC 61588:2009 IEEE Std 1588-2008, 9.3.2, 9.3.3 and 9.3.4. All doubly attached clocks a

41、ccording to IEC 62439-3:2016 shall support in addition the extension to the best master clock algorithm defined in IEC 62439-3:2016, Annex A. All clocks shall support both 1-step and 2-step synchronization on ingress, they may use 1-step or 2-step synchronization on egress. All clocks shall support

42、at least one of the three management mechanisms, as stated in IEC 61588:2009 IEEE Std 1588-2008, 15.1.1: 1) the alternate management mechanism using the SNMP MIB specified in IEC 62439-3:2016, Annex E, and/or 2) the alternate management mechanism using the management objects defined in IEC TR 61850-

43、90-4:2013, 19.3 and 19.4, and/or 3) the manufacturer-defined fixed values and/or the manufacturer-specific implementation means to address all configurable values. For testing purposes, it is recommended to equip clocks with a 1 PPS output, see 7.9. 7 Requirements 7.1 Measurement conditions Steady s

44、tate is defined as 30 s after a single master starts to send synchronization messages and 16 s after a change of master, with no change to the environment temperature. This definition applies only to clocks that have been energized for 30 minutes to accommodate, for instance, temperature-controlled

45、oscillators. 7.2 Network time inaccuracy The following requirements on the network elements aim at achieving a network time inaccuracy better than r1 Ps after crossing approximately 15 TCs or 3 BCs. 10 IEC/IEEE 61850-9-3:2016 IEC/IEEE 2016 7.3 Network elements All network elements shall be clocks ac

46、cording to this part of IEC 61850, conformant media converters and/or conformant links. 7.4 Requirements for grandmasters 7.4.1 Grandmaster time inaccuracy A grandmaster-capable clock shall have a time inaccuracy measured between its applied time reference signal and the produced synchronization mes

47、sages that is smaller than 250 ns. NOTE This value corresponds to an IEC 61588:2009 IEEE Std 1588-2008 clockAccuracy of 22 hex. In case the grandmaster-capable clock has no time reference signal, IEC 61588:2009 IEEE Std 1588-2008, J.4.4.1 shall apply. 7.4.2 Grandmaster holdover A grandmaster shall r

48、emain within the time inaccuracy of 7.4.1 for a holdover time of at least 5 s after losing its time reference signal, given that it was in steady state. 7.4.3 Grandmaster clockQuality in start-up, holdover and recovery A grandmaster clock shall adjust its clockClass according to IEC 61588:2009 IEEE

49、Std 1588-2008, Table 5 with the values: 6 while synchronized to its time reference signal and in steady state; 7 after loss of its time reference signal, while in holdover; 52 after loss of its time reference signal, when its time error exceeds 7.4.1; 187 after loss of its time reference signal, when its time error exceeds 1 Ps; 6 after recovering the time reference signal and in steady state. NOTE 1 This modifies IEC 61588:2009 IEEE Std 1588-2008, Table 5 with the timing requirements of this profile. NOTE 2 The cl
