高压直流输电词汇

[中文适用范围]： 本文件定义了高压直流 (HVDC) 输电系统和使用电子功率转换器进行交流到直流转换的 HVDC 变电站的术语，反之亦然。本文件适用于具有线路换向转换器@的高压直流变电站，最常见的是基于三相桥（双路）连接（见图2），其中使用单向电子阀@例如半导体阀@。对于晶闸管阀@，本文件中仅包含最重要的定义。 IEC 60700-2 中给出了更全面的 HVDC 阀门术语列表。 [外文原描述]： IEC 6033:2019 defines terms for high-voltage direct current (HVDC) power transmission systems and for HVDC substations using electronic power converters for the conversion from AC to DC or vice versa. This document is applicable to HVDC substations with line commutated converters, most commonly based on three-phase bridge (double way) connections (see Figure 2) in which unidirectional electronic valves, for example semiconductor valves, are used. For the thyristor valves, only the most important definitions are included in this document. A more comprehensive list of HVDC valve terminology is given in IEC 60700-2. This edition includes the following significant technical changes with respect to the previous edition: - 40 terms and definitions have been amended and 31 new terms and definitions have been added mainly on converter units and valves, converter operating conditions, HVDC systems and substations and HVDC substation equipment; - a new Figure 13 on capacitor commutated converter configurations has been added. The contents of the corrigendum of February 2020 have been included in this copy.
