Abstract :
Our county distribution power network neutral point grounding modes are divided into three categories: Neutral non-earthing system, neutral-point indirect earthing system and direct neutral earthing system. Neutral-point indirect earthing system is divided into neutral grounded though a resistance and neutral grounding via arc suppression coil. This article is based on the MATLAB power system simulation mode of three kind of neutral grounding modes. The MATLAB create different wave forms when the single phase to ground fault happened, which under the 10kV voltage grade in different neutral-point earthing method of in distribution network. Summed up the application ranges of three grounding modes, which under the 10kV voltage grad in power distribution network.
