摘　　要：本文提出了一种对带有分布式电源(DG)的配电网发生相间故障时的故障定位方法,通过测量系统和分布式电源变电站处的电压和电流来实现故障定位。为了减少计算误差,提出将主变站和DG之间分段的思路。最后应用pscad软件进行仿真,该方法可以有效改善故障定位的性能,适用于相间故障定位。This paper proposes a method of phase to phase fault location in distribution network with distributed generations, reducing the calculation error by measuring voltage and current at systems and distributed power substation to realize fault location. In order to reduce the calculation error, and puts forward the method of segmenting between main transformer station and DG.Finally, this fault location method has been simulated using PSCAD/EMTDC, to show the method can effectively improve the performance of the fault location.
