| Abstract: | Based on the circuit principle of the single-phase voltage compensation active superconducting fault current limiter(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. |
