【Abstract】 Based onthe analysis of the theory to realize selective leakage protection for a three-phase three-wire distribution network system, a theory to realize selective leakage protection for a mix-power supply load systemis proposed containing three-phase and single-phase load . The theoretical analysis , Matlab si mulation, various experiment with emphasis are made.The running conditions on spot indicates that this theory can realize selective leakage protection reliably.更多还原
