摘　　要：介绍了华东电网故障电流限制器示范工程的主电路结构、主要元件参数和工作原理,用PSCAD仿真软件建立了华东500kV电网故障电流限制器(faultcurrent limiter,FCL)的等值系统。在该等值系统上针对FCL对零序电流保护的影响,线路重合闸对FCL的影响及FCL保护与线路保护的配合等问题进行了理论研究和仿真分析,并给出了基于仿真分析的合理的解决方案。The main circuit topology of the fault current limiter （FCL） demonstration project in East China 500 kV power grid was presented and an equivalent system for FCL of East China 500 kV power grid was built by PSCAD. Theoretical research and simulative analysis on the influences of FCL on zero-sequence current protection, the influence of automatic reclosure on FCL and the coordination between FCL protection and line protection were performed, and a simulative analysis-based rational solution was given.
