摘　　要：木里河是雅砻江中游最大支流,目前已形成两库四级梯级水电站群,充分利用梯级末端立洲水库的反调节能力,将有效提升流域整体发电效益。为分析梯级水电最优运行方式,以流域梯级枯期最小出力最大和梯级年发电量最大为目标函数,建立了木里河流域两库四级的优化调度模型,并采用逐渐优化算法(POA)求解,最大化利用末端水库反调节能力。结果表明,通过立洲水库的反调节作用,木里河流域梯级枯水期的可靠出力得到有效改善,发电效益得到有效提升。Muli River is the largest tributary of the middle reaches of the Yalongjiang River, which has formed a cascade hydropower station group with two reservoirs and four stages. By taking full advantage of the reverse regulation ability of the Lizhou Power Station at the end of the cascade, the overall power generation efficiency of the basin will be effectively improved. In order to analyze the optimal operation mode of cascade hydropower stations, a four stage inverse regulation optimal operation model of muli river two reservoirs was established by taking the maximum value of minimum output of cascade hydropower stations in dry season and the maximum value of annual power generation of cascade hydropower stations as the objective functions, and it was solved by using POA algorithm. In this way, the inverse regulation capacity of terminal reservoirs was maximized, and the annual power generation and reliable output of cascade hydropower stations was improved. The results show that the reliable output of cascade in dry season was effectively improved, and the power generation benefit was effectively improved.
