摘　　要：研究随机扰动下简单电力系统的可靠度反馈最大化.应用拟不可积哈密顿系统随机平均法和随机动态规划原理,导出以可靠度最大为目标的动态规划方程和以平均首次穿越时间最长为目标的动态规划方程.通过分别求解相应的动态规划方程,得到最优控制律,受控与未控系统的条件可靠性函数及平均首次穿越时间.最后应用Monte Carlo模拟验证结果的准确性.The feedback maximization of reliability of simple studied. The stochastic averaging method for quasi non-integrab power systems under random perturbations was le Hamihonian systems and stochastic dynamical programming principle were applied to derive the dynamical programming equation for the maximization of condi- tional reliability function and that for the maximization of mean first passage time. The optimal control, the conditional reliability function and mean first passage time of uncontrolled and controlled power system were obtained by solving the corresponding final dynamical programming equations. The proposed method was verified by using Monte Carlo simulation.
