22、NATIONAL ELECTROTECHNICAL COMMISSION _ UHV AC TRANSMISSION SYSTEMS Part 100: General information FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object o

23、f 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 Specifications (

24、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 liaising

25、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 express, as

26、 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 Committees in

27、 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 National Commi

28、ttees 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 not provi

29、de 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 have the late

30、st 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 whatsoever, whet

31、her 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 publications is in

32、dispensable 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. The main task of IEC technical

33、 committees is to prepare International Standards. However, a technical committee may propose the publication of a technical report when it has collected a different kind of data from that which is normally published as an International Standard, for example “state of the art”. The technical report

34、IEC 63042-100 was prepared by IEC Technical Committee 122: UHV AC transmission systems. The text of this technical report is based on the following documents: Enquiry draft Report on voting 122/29/DTR 122/31A/RVC Full information on the voting for the approval of this technical report can be found i

35、n the report on voting indicated in the above table. 6 IEC TR 63042-100:2016 IEC 2016 This document has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts in the IEC 63042 series, published under the general title UHV AC transmission systems, can be found on the IEC

36、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, withdrawn, replaced by a revi

37、sed edition, or amended. A bilingual version of this publication may be issued at a later date. IEC TR 63042-100:2016 IEC 2016 7 INTRODUCTION UHV AC transmission systems are capable of transmitting large amounts of electric power. However, if a failure occurs in a UHV AC system, the system influence

38、 can be severe from the viewpoints of reliability and overall security of the supply of the power system. Most UHV AC substations are located far from city areas, with large equipment in size and mass installed. Equipment is transported over long distances from where it is manufactured and tested to

39、 where it is installed and commissioned. Also, the installation time of equipment is generally longer compared with lower voltage classes. For UHV AC transmission lines, the design of insulation is an important aspect due to non-linearity effect. Therefore, securing the reliability, availability, an

40、d environmental aspects are crucial issues. Standards and/or applications guidance, as relevant, in the following aspects of UHV AC transmission systems exceeding 800 kV are necessary: a) planning (guidance); b) design; c) technical requirements (exclusively systems-related); d) construction; e) com

41、missioning; f) reliability; g) availability (continuity of power supply, % availability); h) operation; i) maintenance. This document describes both specific issues to UHV AC transmission systems and common issues of UHV AC and lower voltage transmission systems because it is very easy to understand

42、 UHV AC transmission systems as a whole. In this Technical Report, minimum items or requirements for the standards and guidelines for each step of UHV AC transmission systems are described. 8 IEC TR 63042-100:2016 IEC 2016 UHV AC TRANSMISSION SYSTEMS Part 100: General information 1 Scope This part o

43、f IEC 63042, which is a Technical Report, specifies the reference for the standards and guidelines for UHV AC transmission systems. This document provides an overview of these standards as well as guidelines. This document is developed to clarify standardization items and/or guideline items for UHV

44、AC transmission systems. It describes the items to be considered for each stage of planning, design, construction, commissioning, operation, and maintenance during the development of IEC publications for UHV AC transmission systems. NOTE Based on this IEC/TR 63042-100, TC 122 will prepare the standa

45、rds and guidelines for UHV AC transmission systems, but it is not limited by the framework of the TR. A systematic approach is necessary for the preparation of systems-oriented specifications such as those for planning, design, technical requirements, construction, commissioning, reliability, availa

46、bility, operation, and maintenance. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.

49、 stands for Ultra High Voltage. 4 Planning 4.1 General Large scale power sources have been developed. It is important to transmit the electric power efficiently from these power sources to consumption areas. Moreover, the network enhancement might decrease the system stability and worsen fault current problems. To IEC TR 63042-100:2016 IEC 2016 9 prevent such problems in existing high voltage transmission systems, multiple transmission lines and switchyards might be necessary due to
