摘　　要：针对配电网中性点消弧线圈接地和小电阻接地方式存在的问题,提出一种新的接地方式——消弧线圈并联选线电阻接地,分析其运行原理和选线电阻选择的依据,利用电磁暂态计算软件(the alternative transients program,ATP)进行仿真,计算结果表明消弧线圈并联选线电阻的接地方式能较好地避开中性点消弧线圈接地和小电阻接地方式存在的问题,适于架空线路和电缆线路混杂的配电网。In view of the problems in distribution network neutral grounding through arc-suppression coil and small resistance, a new grounding mode via arc-suppression coil and line-selecting resistance in parallel is proposed. Its running principle is analyzed along with the basis for choosing the line-selecting resistance. The results of simulation computation using the alternative transients program （ATP） show that the proposed mode can effectively avoid the problems in neutral grounding through arc-suppression coil and small resistance, and adapts well to distribution network combining overhead lines and cable lines.
