Abstract

AbstractBased on the distribution network practical-test-platform, the research work on the realization technology of arc grounding fault in distribution network can be carried out. In this paper, the arc grounding fault model is established, the development process of intermittent arc grounding fault is described in detail, and an arc grounding fault simulation device and a simulation flow are designed. The simulation example of the distribution network practical-test-platform is built on the PSCAD software, and the intermittent arc grounding fault of the neutral ungrounded system and the low resistance grounding system is simulated and analyzed.KeywordsDistribution network practical-test-platformArc grounding faultNeutral ungrounded systemLow resistance grounding system
