根据零序电流相位法故障定位的原理，可以判断配电网的故障区段。文中利用Matlab／Simulink中的仿真模块，对中性点不接地系统进行仿真分析。介绍了仿真模型的搭建，对不同状况下的接地故障进行仿真分析，包括改变接地电阻的大小、线路长度以及有无负载等，总结其影响因素。仿真结果与理论推导一致，从而为其实用化奠定了基础。

The fault section of a distribution network can be judged by the zero sequence current phase fault lo- cation. The article uses the simulation module in Matlab/Simulink to simulate the non-ground neutral system. It in- troduces the building of the simulation model, then simulates and analyses the ground fault in different conditions such as changing the size of the grounding resistance and the length of the line, and with or without load. The simu- lation results agree with the theoretical one, thus laying the basis for practical applications.
