摘要
基于电压补偿型超导故障限流器(SFCL)的单相电路结构和工作原理,提出了一种关于电压补偿型超导故障限流器的三相电路结构,并对其在三相电力系统发生不同故障时的运行特性进行了分析。利用Matlab/simulink建立仿真模型,仿真结果表明该电压补偿型SFCL的三相拓扑结构具有一定的可行性,对系统中发生不同短路故障时的短路电流都具有良好的限制作用。
Based on the circuit principle of the single - phase voltage compensation active superconducting fault current limit- er (SFCL), this paper proposed the circuit structure of a three -phase voltage compensation active SFCL, analyzed the operating characteristics of the SFCL in three - phase power systems failure. The simulation models were built using Matlab/simulink. The simulation results show that the proposed three - phase voltage compensation SFCL topology is of certain feasibility, which has a good fault current limiting characteristic when the different short - circuit faults occur in the power systems.
