电力系统谐波不稳定

Power System Harmonic Instability

说明了谐波不稳定的实质,介绍并分析了国内外发生的谐波不稳定过程。给出一个算例,关系到变压器涌流引发高压直流输电换流器换相失败而系统失稳。

This paper describes the nature of harmonic instability, introduces and analyzes various types of harmonic instability process which take place in China and other countries. An example algorithm is given, which is related to the HVDC converter commutation failure induced by transformer inrush current and the system instability.
