有源滤波器专用高压直流系统(HVDC

[中文适用范围]： 本技术报告提供了关于用于高压直流（HVDC）电力传输的有源滤波器的一般指导。它描述了主要使用有源设备来减少直流或交流系统中的谐波的系统。这排除了自动重新调谐组件的使用。报告中描述了可用于有源滤波器的各种电路类型，以及它们的主要操作特性和典型应用。总体目标是为购买者提供指导，帮助其将有源滤波器作为HVDC转换器的一部分进行规范。本报告特别排除了无源滤波器。 [外文原描述]： IEC/TR 62544:2011(E) gives general guidance on the subject of active filters for use in high-voltage direct current (HVDC) power transmission. It describes systems where active devices are used primarily to achieve a reduction in harmonics in the d.c. or a.c. systems. This excludes the use of automatically retuned components. The various types of circuit that can be used for active filters are described in the report, along with their principal operational characteristics and typical applications. The overall aim is to provide guidance for purchasers to assist with the task of specifying active filters as part of HVDC converters. Passive filters are specifically excluded from this report.
