26、INTERNATIONAL ELECTROTECHNICAL COMMISSION _ HIGH-VOLTAGE DIRECT CURRENT (HVDC) SYSTEMS GUIDANCE TO THE SPECIFICATION AND DESIGN EVALUATION OF AC FILTERS Part 2: Performance FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all
27、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 publishes International Standards, Tech
28、nical 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 may participate in this preparatory wor
29、k. 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 agreement between the two organizations. 2
30、) 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 Publications have the form of recommen
31、dations 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 or for any misinterpretation by any e
32、nd 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 corresponding national or regional public
33、ation 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 for any services carried out by independ
34、ent 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 and IEC National Committees for any per
35、sonal 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) Attention is drawn to the Normative re
36、ferences 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 rights. IEC shall not be held responsible f
37、or identifying any or all such patent rights. The main task of IEC technical committees is to prepare International Standards. However, a technical committee may propose the publication of a Technical Report when it has collected data of a different kind from that which is normally published as an I
38、nternational Standard, for example “state of the art“. IEC TR 62001-2, which is a Technical Report, has been prepared by subcommittee 22F: Power electronics for electrical transmission and distribution systems, of IEC technical committee 22: Power electronic systems and equipment. This first edition
39、 of IEC TR 62001-2, together with IEC TR 62001-1, IEC TR 62001-3 and IEC TR 62001-4, cancels and replaces IEC TR 62001 published in 2009. This edition constitutes a technical revision. PD IEC/TR 62001-2:2016 6 IEC TR 62001-2:2016 IEC 2016 This edition includes the following significant technical cha
40、nges with respect to IEC TR 62001: a) expanded and supplemented Clause 19, and Annex B; b) new Clause 3 on current-based interference criteria; c) new annexes on induced noise calculation with Dubanton equations; d) addition of a TIF requirement in a technical specification, e) specification of IT l
41、imits dependent on network impedance and on the impact of AC network harmonic impedance; and f) specification of voltage level on the filter design necessary to fulfil an IT criterion. The text of this Technical Report is based on the following documents: Enquiry draft Report on voting 22F/410/DTR 2

The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site under “ht
44、tp:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. A bilingual version of this publication may be issued at a later date. IMPORTANT The colour inside logo on the cover page of
