摘　　要：为提高煤矿井下供电系统的供电质量,文章提出了一种基于选相投切技术的自动无功补偿装置,专门针对如何实现在电压过零的时刻闭合真空开关、在电流过零的时刻断开真空开关进行研究。对三相电容器组进行了理论分析,通过MATLAB仿真煤矿井下关断电容器组时刻的过渡过程,得出了电容器组选相投切的最佳相位。In order to improve the power supply quality of the mine power supply system in the underground mine,an automatic reactive power compensation device base on a phase controlled switching technology was provided.A study was conducted on how to close an vacuum switch when the voltage was over 0 and disconnect the vacuum switch when the voltage was over 0.A theoretical analysis was conducted on the three phase capacitor banks.The MATLAB software was applied to simulate a transition process when the capacitor banks was disconnected in the underground mine.An optimized phase of the phase switching was obtained for the capacitor banks.
