Abstract


Our country generally uses small current grounding system (the neutral point no direct grounding system). Due to the fault current is too small to identify. So the distribution network operators have been plagued by this kind of fault line selection accuracy. This research establishes simulink model to analyze the fault of single-phase grounding system with matlab. The simulation and the results are used to guide the fault line selection.
