3-Phase Fault Current Limiter for distribution systems

Abstract

An EMTP RV based study to limit fault currents in a distribution system using a 3-phase version of a solid-state fault current limiter (SSFCL) is presented. 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. Comparisons are also made with a single-phase version of the SSFCL which had been previously presented.
