摘　　要：摘要:介绍了中性点经小电阻接地方式和经消弧线圈接地方式的发展状况,比较了这两种接地方式的优缺点,给出了选择中性点接地方式的一般思路,分析了电网结构、变压器连接组别对中性点接地方式的影响,针对接地电阻阻值的选择、安装位置、消弧线圈补偿形式的优化提出了新观点。The development situation of two kinds of neutral grounding via small resistance and arc suppression coil is described, the advantages and disadvantages of the two grounding modes are compared and the general thinking to select the neutral grounding mode is given. The influence of power network layout and transformer winding connection schemes on neutral grounding modes is analyzed. The author's opinions on the selection of grounding resistance value, its installation position, the optimization of the compensation of arc suppression coils are presented.
