摘要(Abstract)：

可控串联电容补偿(thyristor controlled series capacitor,TCSC)能够控制串联电容器与汽轮发电机轴系之间的能量交换,抑制系统中的次同步分量,从而避免发生次同步谐振的风险。对TCSC抑制次同步谐振(sub-synchronous resonance,SSR)的2种不同方法,即自然抑制和主动抑制,进行了分析和对比,设计了次同步阻尼控制器,研究了TCSC在不同触发角下及附加了阻尼控制器的主动抑制下对次同步谐振抑制的效果,通过PSCAD/EMTDC对这些方法进行时域仿真发现,2种方法均能有效抑制SSR,而主动抑制的效果更好一些。

关键词(KeyWords)： 可控串补;次同步谐振;次同步阻尼控制器
