摘　　要：煤矿井下生产过程中大型设备运行所产生的无功对电网质量和煤矿监控设备造成了巨大的影响,需要使用矿用隔爆型无功补偿器(SVG)补偿无功以提高功率因数,井下660V电网环境同样需要多电平结构来降低开关管的电压应力。对二极管箝位型三电平结构作为主拓扑的矿用隔爆型静止无功补偿器SVG进行了研究,对控制系统延迟造成的电流环延迟于电压环而引起自身功率因数不为1的现象进行了分析,并提出了利用补偿电流环相位的方法补偿控制系统延迟的解决方案。Running medium-large size equipment created reactive which had great effects on power network quality and monitoring equipment during productive process underground coal mine. The effects require mining flame-proof reactive power compensator （SVG） to compensate the reactive power and increase power factor, and 660 V power grid environment requires multilevel structures to reduce voltage stress of switching tube underground coal mine. The authors studied the diode clamp tri-level structure as the main topology of mining flame-proof static reactive compensator （SVG）, analyzed phenomenon of control system delay caused current loop delayed in the voltage loop which gave rise to power factor of itself was other than 1, and put forward the compensation method of current loop phase delay compensation control system.
