It is expected that a number of dispersed generators interconnecting with power distribution systems will be increased with progress of deregulation in electric power industry. In order to allow large capacity of the interconnection, a certain current limitation measure is required in present distribution systems because of allowable short circuit capacity as a restriction. One of effective measures is fault current limiter (FCL) which suppress short circuit current within a time of half cycle. However, a required performance of FCL applied to dispersed generators is not made clear. The authors look for necessary conditions on the FCL performance for above-mentioned purpose using EMTP simulation. This paper presents necessary performance of FCL, which includes a commutation type FCL with resistance and reactance as a limitation element.
