本文提出了一种用暂态最优控制来改善电力系统暂态稳定性的新方法，它是前一篇文章的继续。本质上，系统状态是通过bang-bang控制以无振荡的方式从暂态开始时的状态转移到暂态后的稳定状态。从而显著地有助于瞬态稳定性的改善。考虑了具有两条联络线的电力系统模型。它示出的控制过程可以实现与两个间歇工作串联电容器或电容器和电抗器。最优控制器的合成和现实的性能指标的评价结果与实际考虑一起沿着。
This paper presents a new approach to the problem of improvement of transient stability of a power system by means of optimal control of transients and is in continuation of the work reported in a previous paper.1 Essentially the system state is transferred from that at the beginning of the transient to a post-transient steady state in a nonoscillatory manner by means of a bang-bang control, thereby contributing significantly to the improvement of transient stability. A power system model with two interconnecting tie-lines is considered. It is shown that the control process may be implemented with two intermittent duty series capacitors or a capacitor and a reactor. Results of the synthesis of the optimal controllers and evaluation of realistic indices of performance are presented along with practical considerations.
