Abstract

This study presents an analysis of short circuit currents and double ground connection in high-tension and medium tension distribution networks integrated with dispersed generation. The calculation of regime parameters are done using special design simulator, giving characteristics of Bulgarian distribution networks. We evaluate the magnitude number of short circuit and a double ground fault when the dispersed generations are joined to distribution network.
