结合黄河中上游梯级水库，本文研究了多年调节水库起调水位对联合调度的影响，提出了获取多年调节水库年末消落水位控制规则和风险分析方法。该研究对多年调节水库调度运用具有重要的实用价值。 Combined with the cascade reservoirs in the middle and upper reaches of the Yellow River, this paper studies the effect of adjusting the water level of the reservoir for many years on the joint dispatch, and puts forward the control rules and risk analysis methods for attaining the year-end fluctuation level of the multi-year regulating reservoir. This study has important practical value for regulating reservoir operation and utilization for many years.
