摘要
本文首次建立了电力系统中非同期合闸过电压的时延控制系统的数学模型，得到了相应闭环系统的稳定性以及振动性，同时利用时延控制系统次优控制的灵敏度系数研究方法，得到了该系统的次优控制设计方法及相应的次优控制设计过程，最后我们结合采样数据，利用泛函微分方程的分布迭代方法进行数值计算，得到了均优于已有文献的结果．
The control systems model of over-voltage produced by nonsynchronous closing was first set up in the power systems, the oscillation and stability of the closed-loop system of the model are obtained by using analysis 1 and by using the sensitivity coefficient method of time-delay control systems,we obtain suboptimum and its designing process of the model,and by using the fractional iterative methods of functional differential equations,the obtained theory results and computing results are better than the one from other appeared models that already presented results.
