EMTP RV-based study of solid-state fault current limiter for distribution systems

A fault current limiter (FCL) can reduce the fault current in a feeder system to a desired level and permit continuous power to be fed to loads. An EMTP RV based study to limit fault currents in a distribution system using a solid-state fault current limiter (SSFCL) is presented in this paper. For demonstration purposes, two types of distribution systems have been considered: a single-source radial system and a multiple source distribution system with a bus-tie. Simulations have been done for different types of faults to show that the SSFCL is effective for limiting fault currents
