标准摘要
[中文适用范围]： 本部分IEC 62751规定了计算电压源换流器(VSC)换流阀功率损耗的一般原则，适用于高压直流(HVDC)应用，与换流器拓扑无关。标准第6、8条及第9.1、9.2和A.2.12子条款也可用于计算动态制动阀(如使用)的功率损耗，并作为计算STATCOM装置阀功率损耗的指导。 HVDC变电站中除换流阀外的其他设备的功率损耗不在本标准范围内。VSC变电站中大多数设备的功率损耗可采用与IEC 61803中线路换相换流器(LCC)HVDC系统规定的类似程序计算。附录A介绍了LCC和VSC HVDC变电站之间的主要差异，这些差异会影响其他设备功率损耗的确定方法。 本标准不适用于线路换相换流器HVDC系统的换流阀。 [外文原描述]： IEC 62751-1:2014+A1:2018 sets out the general principles for calculating the power losses in the converter valves of a voltage sourced converter (VSC) for high-voltage direct current (HVDC) applications, independent of the converter topology. Several clauses in the standard can also be used for calculating the power losses in the dynamic braking valves (where used) and as guidance for calculating the power losses of the valves for a STATCOM installation. This consolidated version consists of the first edition (2014) and its amendment 1 (2018). Therefore, no need to order amendment in addition to this publication.
