-This paper analyzed the selection of practical impedance of Superconducting fault current limiter (SFCL) on bus tie in a power distribution system. Generally, the parallel operation of main transformer offers a number of advantages. However, when a fault occurred in the parallel operation of main transformer, the fault currents could exceed the capacity of conventional protective device and might generate protective coordination problems. To solve these problems, the SFCL has been studied as the attractive device. Especially, in power distribution system on bus tie with SFCL, the effect of the resistance of SFCL could decrease the increased fault currents and could meet the capacity of conventional protective devices by them. Also, they could solve the protective coordination problems. Therefore, we analyzed the practical impedance of SFCL on bus tie in a power distribution system using PSCAD/EMTDC.
In this paper, the effects on the protective coordination of a superconducting fault current limiter (SFCL) with the protective devices were analyzed. The SFCL has been noticed as the best solution to limit fault current effectively, which has continuously increased due to the expansion of the power facilities for the increased power demand.
