摘要: 针对引汉济渭工程运行初期三河口水库研究不足，开展三河口水库多目标调度规律的研究。考虑工程调水、发电和生态需水等要求，建立水库多目标优化调度模型，采用NSGA-II求解模型。从调度指标、调度目标、影响因素和调水潜力等方面分析计算结果，揭示了多目标转化规律，量化了起调水位对发电量的影响，验证了优化模型计算结果的合理性和优越性。研究表明：1) 小幅降低发电量可显著增加调水量；2) 三河口水库在丰水年、平水年能够满足规划值，但枯水年不能满足；3) 起调水位对发电量影响显著；4) 典型年最大调水8.75亿m3；最小调水3.75亿m3。研究成果对水库运行、提高水资源利用效率和工程效益提供了重要参考。
Abstract: The multi-objective operation for Sanhekou reservoir is analyzed for the Hanjiang to Weihe River Water Transfer Project at early stage, which is rarely investigated. Considering the project demands of transferred water, power generation, and ecology, a multi-objective model is established, and NSGA-II is proposed to solve the model. The optimal results are analyzed from operation indicators, operation goals, influencing factors and water transfer potential; the multi-objective transformation rule was revealed; the initial operation water level on the impact of power generation is quantified; the rationality and superiority of the optimization model results are verified. Research shows: 1) The transferred water can increase dramatically with slight decrease in power generation; 2) Design values of Sanhekou Reservoir can be met in wet year and normal year, but can’t be met in dry year; 3) Initial operation water level has a significant impact on power generation; 4) The maximum transferred water in typical year is 875 million m3; the minimum transferred water is 375 million m3. The study results provide important reference for reservoir operation, improving water resource utilization efficiency and project benefit.
