Compared with fixed series compensation,the advantage of TCSC is that it can adj ust line impedance swiftly in response to the changes when the system is running without bringing SSR. Triggering precisely is the key point in realizing TCSC c ontrol.

• 可控串补 (TCSC)相对于固定串补的优势在于它可以快速灵活地调整线路阻抗以响应系统运行变化且不会引起次同步谐振 (SSR) ,而能否准确地触发 TCSC则是实现其阻抗控制的关键所在。
