摘　　要：为有效利用水能资源,苏北灌溉总渠沿线高良涧闸、运东闸、运西分水闸及阜宁腰闸4座水闸两侧均装设了水轮机组,组成了成梯级混联式布置水电站。为获得最大经济效益,实现站间最优水位组合调度,采用期望值模型构建法建立由4个水电站组成的水电站群总发电效益模型,应用动态随机最优控制中极值理论分析研究了水电站机组流量和水头及上下游电站间水位的联系,计算出发电效益最大的联合最佳水位,以实现4座梯级混联水电站联合优化调度。In order to utilize the hydropower resources effectively, the hydropower turbines were installed on both sides of the sluices along the Subei irrigation canal, including Gaoliangjian sluice, Yundong sluice, Yunxi diversion sluice and Funingyao sluice. The 4 sluices formed cascade hydropower stations. In this paper, it establishes the model of the total power generation efficiency of the 4 hydropower stations by the expected value model construction method, studies the relationship between the flow rate and the water level of the hydropower stations by extreme value theory in dynamic random optimal control, and calculates the optimal combined water levels of the maximum power efficiency. The conclusions present the joint optimal operation of the 4 cascade hydropower stations to achieve maximum economic benefits and the optimal combined water levels scheduling.
