摘　　要：分布式电源的并网影响了配电网的可靠性。为更有效地限制有分布式电源时的故障电流,探讨为超导故障限流器寻找最佳位置。在MATLAB中对环形配电网中不同位置发生三相短路进行了仿真,通过仿真的数据确定了在含有分布式电源的环形配电网中超导故障限流器的最佳安装位置。The grid connection of distributed power supplies affects the reliability of distribution network.In order to more effectively limit the fault current with DG,the optimal position of superconducting fault current limiter is discussed.The MATLAB simulation of three-phase short circuit at different positions in the ring distribution network is carried out,and the optimal installation position of SFCL in the ring distribution network containing DG is determined with simulation data.

关 键 词：故障电流 分布式电源 超导故障限流器
