Abstract

For conducting the fault analysis in a system with distributed generation, the sequence equivalent circuit is used. Due to the characteristics of distributed generation that reverse currents occur, the size of the fault current can be determined by the path where fault current can flow into the fault point in the negative sequence and zero sequence. In this paper, we calculate and compare the fault currents in the system with inverter-based distributed generation considering the topology of transformer winding. From the results, we can analyze the effect of the interconnection transformer in the fault analysis.
