摘　　要：本文提出了一种用晶闸管开关装置———串联变压器改变电容端电压调节无功的补偿方法。阐明了这种补偿装置原理 ,分析了装置功率特性 ;估计了晶闸管开关换接过程的断态过电压和过电流大小 ,指出了降低这种过电压和过电流技术实现完全可能。并以实例和TSC进行了比较 ,指出了这种装置成本要比TSC低得多 ,宜于在高压电网中使用。This paper advanles a method for VAR compensation using a device of thyistor switch series transformer changing capacitance voltage. The principle of the compensation device is described and power characteristic is analysised. Only a little power passing through thyristor is pointed out, so the less capacity of thyristor is needed. Overvoltage and overcurrent in the proceeding of thyristor switch converted is estimated. Indicate it is possibility for reducing overvoltage and overcurrent. By comparing with TSC, points out the cost of device is less than TSC. The device is suit to high voltage power network.
