Simulation Study on Neutral Grounding Mode in Distribution Network

Xudong Fang

Abstract

There are three traditional grounding ways of neutral point in distribution network in China,i.e.isolated neutral,the neutral point by arc suppression coil grounding and neutral point grounded through the resistor.The paper describes the advantages and disadvantages of them.Single-phase ground fault is simulated in Matlab/Simulink.At last,the reasonable grounding modes for different situations are put forward.
