针对电气化铁路牵引变电站存在无功波动大、功率因数低的问题，提出了应用晶闸管控制高阻抗变压器(TCT)型静止无功补偿(SVC)进行动态无功补偿的解决方法。分析了TCT型SVC的补偿原理，以某铁路牵引变电站动态无功补偿为例，说明TCT型SVC投运后能快速跟踪负荷无功变化需求，功率因数明显提高，电压稳定性得到改善，并取得良好的经济效果。

For the existing problem of great reactive power lfuctuation and low power factor in the electriifed railway traction substation, this paper proposed to use the thyristor controlled high impedance transformer (TCT) type static var compensation (SVC) to compensate reactive power dynamically. The compensation principle of TCT type SVC was analyzed. The dynamic SVC of certain railway traction substation shows that TCT type SVC can fast track the load reactive power, the power factor is improved obviously, the voltage stability is improved and the economic effect is well achieved.
