摘要: A conventional superconducting fault current limiter (SFCL) is usually only connected to a power system for limitation. The study described in this paper, however, attempts use the hybrid SFCL application reduce transformer inrush current. To accomplish this, paper first suggests concepts expand scope of system. operator should determine proper amount current-limiting resistance (CLR) SFCL. Therefore, decision scheme optimal insertion an This and model are implemented using electromagnetic transient program (EMTP). We CLR by EMTP simulation, value applied EMTP. simulation results show validity effectiveness suggested ability
