摘要
针对煤矿电网功率因数下降、电网传输效率降低的现状,提出了一种新的煤矿供电系统无功补偿技术,采用TSC(晶闸管投切电容器)及SVG(静止无功发生器)相结合的控制方案,利用混合补偿控制装置实现了对煤矿供电系统的无功补偿,具有补偿容量大、补偿灵活性高、连续输出性强的优点。
Aiming at the current situation that the power factor of coal mine power grid decreases and the transmission efficiency of power grid decreases,this paper proposes a new reactive power compensation technology for coal mine power supply system,combining TSC(thyristor switching capacitor)and SVG(static var generator)to realize the reactive power compensation of the coal mine power supply system by using the hybrid compensation control device,which has the advantages of large compensation capacity,high compensation flexibility and strong continuous output.
