Abstract

We have investigated an effect of a fault current limiter (FCL) which is installed at an incoming feeder of a customer system having a synchronous generator in a utility distribution system. It was assumed that either of two types of FCL were installed, a resistive type (R-type) FCL and an inductive type (L-type) FCL. A fault current out of the customer system and a line voltage in the customer system were calculated following a three-phase short circuit fault occurrence. It was found that the range of the limiting impedance for the L-type FCL to suppress the fault current out of the customer system and the voltage sag in the customer system is larger than that for the R-type FCL.
