摘　　要：目前水库中长期优化调度的研究主要集中在模型的构建和求解方面,对于最优调度结果的研究却很少。通过构建水库中长期发电优化调度数学模型,并采用离散微分动态规划法(DDDP)进行求解最优调度结果。以隔河岩为研究实例,提出4类水电站运行方式和6类水库运行方式,分析隔河岩水电站运行方式特性。结果表明,河岩水电站运行方式以最小出力和加大出力为主,而水库运行方式则是以“V型”和“上限水位型”为主;并且,“V型”和“蓄水型”运行方式中,不出现水电站的破坏出力运行方式,“上限水位型”运行方式中,不出现水电站的最小出力运行方式。The mid-long term reservoir operation mainly focuses on the construction and solution of models, and few studies discuss the optimal dispatch results. A mid-long term reservoir operation model which takes the maximum energy generation as objective function is established and uses discrete differential dynamic programming method (DDDP) to obtain optimal scheduling results. Taking Geheyan Reservoir as a Case study, 4 types of hydropower station operation modes and 6 types of reservoir operation modes are proposed and analyzed. The results show that the hydropower operation mode is mainly based on minimum output and increased output, while the operation mode of the reservoir is mainly based on “V-shaped type” and “upper-limit water level type”. Moreover, in the “V-shaped type” and “storage type” operation mode, the failure output operation mode of hydropower station does not appear. In the “upper limit water level type” operation mode, the minimum output operation mode of hydropower station does not appear.
