渠道梯级电站群优化调度

Optimal Operation of Cascaded Hydro-power Stations on Irrigation Canal

本文在经验总结与理论分析基础上,提出了渠道梯级电站群优化调度的分解协调模型,并采用模拟与动态规划相结合的方法,求解了海南松涛灌区东干渠上五级电站群的优化调度问题,采用了以站前水位变幅为控制变量的站内及站群系统调控方式,方法简单可行,经济效果较好。

A 2-level decomposition and coordinate approach are established based on a theoretical study of optimal operation of cascaded hydropower sta-tions on irrigation canal, which is solved with combined technique of a sim-ulation algorithm for the first level and a dynamic programming for the sedond. This approach has been used for 5 cascaded hydro-power stations in East Main Canal of Song Tao Irrigation Area, Hai Nan Province, with the controlling variable of water head variation at the inlet. It has been proved that this approach is very simple in controlling and beneficial in economy.
