초록
Increase of fault current due to larger power demand has increased the possibility of the breakdown of the power system. To protect the power system effectively from the larger fault current, several countermeasures have been proposed. Among them, the superconducting fault current limiter (SFCL) has been expected as one of the most effective solutions. In this paper, the fault current limiter, which consists of a ideal switch as a trigger part and the limiter as the limiting part, has been applied into the distribution system. From the analysis for the fault current limiting operation of SFCL, the inserting resistance's magnitude has been confirmed to affect OCR trip time in a short-circuit of distribution system.
