摘要
本文将变结构控制系统理论引入大规模电力系统暂态稳定控制,研究了大规模电力系统暂态稳定的变结构控制系统的滑动运动,构造了变结构控制函数和开关函数,提出并证明了大规模电力系统暂态稳定变结构控制系统滑动运动的存在性和稳定性定理,及系统的渐近稳定性定理。在理论研究的基础上,进行了考虑发电机调速系统和不考虑调速系统两种情况的模拟计算,并均得到了较好的结果。
A new control approach is proposed for multimachine power systems during transient crises. The variable structure control system theory is applied to choose an appropriate switching function where each component of control is assumed to undergo discontinuity, to design the control law, and then to analyse conditions for the existence of multimachine power systems. The cases containing fast valving of generators or not are simulated to show the effectiveness of the control approach for the systems during transient crises.
