摘　　要：以李家峡双排机水电站为实例,开展双排机水电站综合优化运行研究,通过真机测试分析,得出了李家峡双排机水电站机组稳定性特征和机组效率变化规律,提出了双排机水电站优化运行模式。构建了双排机水电站运行综合优化模型,提出了机组效率、运行稳定性以及电站发电效益多目标同步优化策略。最后,采用实际运行数据对所提模型和方法进行了验证。得出的优化方案满足各项约束条件,并同步实现了多项预期目标,耗水率指标优化幅度达3.12%。结果对类似工程具有借鉴价值。Research on multi-objectives optimal operation of the hydropower station with two-row placed units is studied with an example of Lijiaxia hydropower station. Stability characteristics and operation efficiency of the tworow placed units is studied by real test and analysis. Optimal operation mode is also proposed. Optimal opertion model is constructed with efficiency and stability, generation benefit as the multi-objectives and synchronous optimal strategy is also put forward. Finally, the model and theory is verified by real data. Optimal solution satisfies all the restrictions and realizes the expected multi-objectives. Water waste rate is decreased by 3.12 percents.
