| 摘 要： | 首先介绍了配电网的3种接地方式(不接地、经电阻接地、谐振接地)的原理和特点,然后利用MAT LAB仿真平台,对某10kV配电网的这三种接地方式进行了仿真比较,针对该配电网的输电线单相接地问题给出了较为准确的数值仿真解,指出了中性点经消弧线圈接地方式是目前比较合理的接地方式。

| Abstract: | Theory and characteristic of three kinds of grounded modes including ungrounded,grounded through a small resistance,resonant grounded are presented. After simulating and comparing these three grounded modes of a 10 kV distribution network with the graphics simulating software MATLAB, this paper derives resonant grounded is a rather proper grounded mode. |

| Keywords: | distribution network resonant grounded extinction coil simulation |
