可控串联电容器已被提出来抑制双机电力系统中大瞬态干扰引起的功率波动。在本文中，作者提出了一种时间最优串联电容器控制来抑制多机电力系统中的区域间模式。为了找到切换线，他们将慢相干变换应用于全电力系统，并将从轨迹反转方法找到的慢子系统轨迹投影到主要区域间模式上。通过对具有两种区域间模式的六机电力系统的时间仿真来说明该方法，并显示出给出了期望的结果。
Controllable series capacitors have been proposed to damp power swings resulting from large transient disturbances in two-machine power systems. In this paper, the authors propose a time-optimal series capacitor control to damp interarea modes in multi-machine power systems. To find the switching line, they apply the slow coherency transformation to the full power system and project a slow subsystem trajectory found from the trajectory reversing method onto the predominant interarea mode. The method is illustrated by the time simulation of a six-machine power system with two interarea modes and is shown to give the desired result.
