摘　　要：介绍了主动过电压保护的概念。通过动态模拟实验研究了利用可控串补硬件bypass运行模式限制系统故障期间串补电容两端过电压、减小短路电流的作用,提出了在系统发生短路故障时,减小短路电流,保护电容器的有效控制策略。This article introduces the conception of initiative overvoltage protection.Through the dynamic simulation test,using TCSC hardware bypass mode of operation,which can restrict the overvoltage of the series compensation capacitance and reduce the short circuit current,has been studied.An effective control strategy is proposed to reduce short-circuit current and protect capacitor when short circuit fault happened in power system.

关 键 词：可控串联补偿 主动过电压保护 短路电流
