모의배전계통에 초전도한류기 적용위치에 따른 고장전류 저감 분석

Lately, because of the increasing demand for electrical power, the transformer capacity is increased. Hence, the impedance of system decreases. From this, the fault current is increased. One of the solutions to limit fault current is superconducting fault current limiter (SFCL). The research using the SFCL has not much progressed in a transmission power system. In this paper, we analyed the cases to apply SFCL in a transmission power system. We consist of the simple transmission system and examine whether to operate SFCL on the magnitude of the fault current.
