摘要
我国有几条采用串补的大容量远距离输电线路发生了次同步谐振(SSR)。本文以某电厂为例介绍SSR对发电机造成的破坏,由此探讨汽轮发电机如何应对SSR的问题。
Subsychronous resonance(SSR)have happened in China long transmission line with series capacitor compensation.Fatigue failure of generator rotor has been caused by SSR.Protective measures from generator point of view will be discussed in this paper.
