采用线路换流器的高压直流（HVDC）换流站功率损耗的确定

[中文适用范围]： 此文件适用于公用系统中用于功率交换（功率传输或背靠背安装）的所有线换流高压直流（HVDC）换流站。此文件假设使用12脉冲晶闸管换流器，但在适当谨慎的情况下，也可用于6脉冲晶闸管换流器。在某些应用中，同步调相机或静态无功补偿器（SVC）可连接至HVDC换流站的交流母线。此类设备的损耗确定程序不包括在本文件中。此文件提出了一套标准程序，用于确定HVDC换流站的总损耗。这些程序涵盖除上述情况外的所有部分，并针对空载运行和运行损耗及其计算方法，尽可能使用测量参数。与本文档假设的典型设计相比，采用新颖组件或电路配置的换流站设计，或配备可能影响损耗的不寻常辅助电路的设计，将根据其自身优势进行评估。 [外文原描述]： IEC 61803:2020 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 61803:2020 applies to all line-commutated high-voltage direct current (HVDC) converter stations used for power exchange (power transmission or back-to-back installation) in utility systems. This document presumes the use of 12-pulse thyristor converters but can, with due care, also be used for 6-pulse thyristor converters. In some applications, synchronous compensators or static var compensators (SVC) may be connected to the AC bus of the HVDC converter station. The loss determination procedures for such equipment are not included in this document. This document presents a set of standard procedures for determining the total losses of an HVDC converter station. The procedures cover all parts, except as noted above, and address no-load operation and operating losses together with their methods of calculation which use, wherever possible, measured parameters. Converter station designs employing novel components or circuit configurations compared to the typical design assumed in this document, or designs equipped with unusual auxiliary circuits that could affect the losses, are assessed on their own merits. This edition includes the following significant technical changes with respect to the previous edition: - to facilitate the application of this document and to ensure its quality remains consistent, 5.1.8 and 5.8 have been reviewed, taking into consideration that the present thyristor production technology provides considerably less thyristor parameters dispersion comparing with the situation in 1999 when the first edition of IEC 61803 was developed, and therefore the production records of thyristors can be used for the power losses calculation; - the calculation of the total station load losses (cases D1 and D2 in Annex C) has been corrected.
