摘　　要：随着城镇化民生用水需求迅速增加,水库调度面临巨大的挑战,兼顾民生与发电用水需求的调度策略成为保障工程高效运行的重要软技术手段。通过NSGA-Ⅱ算法建立水库运行的多目标优化调度模型,开展水库需求改变后的调度策略研究,并以缺水度衡量水库调度策略的优劣。按照综合最优目标,在优先保障民生用水的前提下,运行调度策略不仅可以增加发电量,还可以减少用水需求重大改变后对自然水资源的依赖,提高水库效能利用水平,达到提升整体工程经济效益的研究目标。With the rapid increase in the demand for water,for urbanization and people’s livelihood,reservoir dispatch is facing huge challenges.The dispatch strategy that takes into account the people’s livelihood and the demand for power generation water has become an important soft technical means to ensure the efficient operation of the project.The NSGA-Ⅱalgorithm is used to establish a multi-objective optimal scheduling model for reservoir operation,to carry out research on the scheduling strategy after the demand of the reservoir changes,and to measure the pros and cons of the reservoir scheduling strategy by the level of water shortage.According to the comprehensive optimal goal,under the premise of giving priority to the protection of people’s livelihood water,the operation scheduling strategy can not only increase the power generation,but also reduce the dependence on natural water resources after major changes in water demand,and improve the efficiency and utilization of the reservoir to achieve the research goal of improving the economic benefits of the overall project.

关 键 词：水库调度策略 多目标优化调度 水资源高效利用 NSGA-Ⅱ算法 发电效能
