摘　　要：介绍了带旁路电感的新型桥式固态限流器的拓扑,并对控制策略进行了改进,使得发生不对称故障时仅断开故障相桥臂,非故障相可继续运行一段时间。研究了固态限流器在单机无穷大系统中对发电机功角稳定的影响。仿真验证了改进的控制策略的正确性以及固态限流器对三相短路情况下功角失稳的抑制作用。Introduction was made to the topology of a new type bridge solid-state fault current limiter with bypass inductance. The control strategy was improved to break the fault phase bridge arm only on occurrence of asymmetry faults with non-fault phase still in running for a period of time. Study was made on impacts of solid-state fault current limiters on generator power angle stability in single machine infinite-bus system. Simulation has verified correctness of the improved control strategy and restricting function of solid-state fault current limiters for power angle instability under the conditions of three-phase short circuit.
