Abstract

The increase of fault current due to larger power demand has caused the capacity of power machines in grid to increase. 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. Therefore, to introduce SFCL into power distribution system, the analysis on protection in power distribution system with SFCL is essential. In this paper, the problems of the protective coordination in power distribution system with SFCL were described.
