提出了一种新型的故障限流器（FCL），它由传统的限流电抗器和可控串补器（TCSC）串联而成。在正常运行时，它可以补偿电容器和线路的阻抗，同时在系统故障时限制短路电流。在故障清除后，它抑制了功率振荡。通过数字仿真和模拟仿真研究了故障电流抑制的有效性和对电力系统振荡的阻尼作用。结果表明，该限流器可以降低传统可控串补电抗器的感性阻抗，并具有良好的阻尼特性。通过对FCL协调保护系统的研究表明，TCSC中晶闸管的快速旁路对过电压保护、故障限流和降低与TCSC并联的保护避雷器容量都有一定的作用。© 2002 Wiley Periodicals，Inc.

A new Fault Current Limiter (FCL) is proposed which consists of a conventional Current Limiting Reactor (CLR) and a Thyristor‐Controlled Series Compensator (TCSC) in series. In normal operation, it works to compensate for impedance of the CLR and a line, while it limits short‐circuit currents during system faults. After the fault clearance, it damps power oscillations. Effectiveness of fault current suppression and damping effects on power system oscillations were studied by digital simulations and by an analogue simulator. It was found that the proposed FCL could decrease impedance of a conventional CLR reactor due to inductive impedance of the TCSC and have good damping characteristics. From investigation of cooperative protection system for the FCL, it showed that fast bypasses of the thyristors in the TCSC were useful for overvoltage protection, fault current limit and decrease in capacity of protective arresters connected in parallel with the TCSC. © 2002 Wiley Periodicals, Inc.
