FACTS-串联补偿 的基本思想是在输电线上串联接入设备，以改变线路的静态和动态特性，达到改善电网运行性能的目的。

串联补偿普遍应用的是无功补偿，一般是在线路中串入固定电容或电感。

-The basic idea FACTS- series compensation series-compensated transmission lines are connected in series on the access device, to change the static and dynamic characteristics of the line, to achieve the purpose of improving the performance of the grid. Series compensation is widely used reactive power compensation, usually in series with the fixed line capacitance or inductance.
