21、HIGH VOLTAGE DIRECT CURRENT (HVDC) POWER TRANSMISSION Part 2: Terminology FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote int
22、ernational 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 (PAS) and Guides (hereaf
23、ter 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 with the IEC also partic
24、ipate 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 nearly as possible, an
25、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 that sense. While all r
26、easonable 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 Committees undertake to apply
27、 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 provide any attestation of co
28、nformity. 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 latest edition of this publi
29、cation. 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, whether direct or indirect,
30、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 indispensable for the corr
31、ect 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 Standard IEC 60700-2 has been prepared b
32、y subcommittee 22F: Power electronics for electrical transmission and distribution systems, of IEC technical committee 22: Power electronic systems and equipment. The text of this standard is based on the following documents: CDV Report on voting 22F/373/CDV 22F/395A/RVC Full information on the voti

The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC website under “http:/webstore.iec.ch“ in the
35、 data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended.

41、 a bridge, for example between an AC terminal and a DC terminal Note 1 to entry: The main function of a converter arm is conversion. 4.2 converter bridge equipment used to implement the bridge converter connection, if used SEE: Figure 1 Note 1 to entry: The term “bridge“ may be used to describe eith
42、er the circuit connection or the equipment implementing that circuit. SOURCE: IEC 60633: 2015, 6.2, modified The expression “and the by-pass arm“ has been deleted from the definition. 4.3 converter unit indivisible operative unit comprising all equipment between the point of common coupling on the A
43、C side and the point of common coupling on the DC side, essentially one or more converter bridges, together with one or more converter transformers, converter unit control equipment, essential protective and switching devices and auxiliaries, if any, used for conversion SEE: Figure 1 Note 1 to entry
44、: If a converter unit comprises two converter bridges with a phase displacement of 30 degrees, then the converter unit forms a 12-pulse unit. 5 Converter performance 5.1 forward direction conducting direction direction of current through a valve, when current flows from the anode terminal to the cat
45、hode terminal 5.2 reverse direction non-conducting direction direction of current through a valve, when current flows from the cathode terminal to the anode terminal 6 Thyristor valve design 6.1 thyristor bi-stable semiconductor device comprising three or more junctions which can be switched from th
46、e off-state to the on-state Note 1 to entry: Devices having only three layers but having switching characteristics similar to those of four-layers devices may also be called thyristors. Note 2 to entry: The term “thyristor“ is used as a generic term to cover the whole range of PNPN type devices. It
47、may be used by itself for any member of the thyristor family when such use does not result in ambiguity or BS EN 60700-2:2016IEC 60700-2:2016 IEC 2016 7 misunderstanding. In particular, the term “thyristor“ is widely used for reverse blocking triode thyristor, formerly called “silicon controlled rec
48、tifier”. Note 3 to entry: Thyristors may either be electrically triggered thyristor (ETT） or light triggered thyristor (LTT). 6.2 electrically triggered thyristor ETT thyristor triggered by applying electrical pulses to the thyristor gate Note 1 to entry: This note applies to the French language onl
