| Abstract: | To solve the problem of locating single-phase grounding fault section of 10 kV feeders in power distribution system,this paper presents a virtual value method based on zero-sequence current of sections. Simulation experiment with ATP-EMTP and data processing with Matlab demonstrate that the proposed method is correct.The method is simple in theory,and not influenced by grounding resistance, fault time,and sampling nodes. It has some practical values. |
