优化控制理论在稳定矿区电网中的应用

应用优化控制原理选择控制作用,按要求的控制作用使系统在给定的时间内最大可能地接近目标值,应用哈密顿函数方法的最大值原理,对非线性微分方程组求解,解析出待求的最优控制量。以此来研究矿务局内部区域电网的合理稳定运行机理,并对全局电力系统负荷动态性能进行分析,在南网和北网共同实施稳定措施,有效地防止因负荷扰动引起的系统变化。

Application of optimized control theory to stabilize mine electric power network

With the application of the optimized control principle to select the control function,the required control function could make the system maximally reaching the target value within the given time.With the max value principle of the Hamilton function method,the nonlinear differential equation was resolved and a max control value required was obtained.All those obtained are for the research on the rational stable operation mechanism of the mine internal electric power network.The loading dynamic performances of the electric power system were analyzed.The south electric power network and north electric power network jointly with stable measures could effectively prevent the system changes caused by the loading interferences.
