一种新型故障限流器在电力系统中的应用研究

Application and Research of New Fault Current Limiter in Power System

提出了一种基于集成门极换流晶闸管IGCT和固态电力电子开关的故障限流器,它由电感和IGCT等组成。正常时,串在电路中,基本无能量损耗,故障时控制短路电流大小。通过PSCAD的仿真分析和现场试验,证明了其有良好的限流性能,可以作为电力系统中有效的保护设备。

A fault current limiter based on integrated gate commutated thyristors （IGCT） and solid - state power electronic switches is proposed, which consists of components such as inductors and IGCT. It is in series with the circuit without energy loss on the whole in the normal state, while in the fault state, it controls the amplitude of short - circuit current. By PSCAD simulation analysis and field test, its good performance of current limiting is proved, which can be used as the effective protec- tion equipment in power system.
