梯级水库联合运行的水库水位控制方式是充分发挥梯级水库综合经济效益的重要课题,尤其是对具有较强调节能力的大型梯级水库,联合运行的梯级水库蓄水水位,消落水位控制方式的合理性和有效性决定了梯级电站综合效益的好坏.本文以雅砻江下游梯级水库为例,建立了梯级水库群优化调度模型,提出并采用二重逐步优化计算方法,探讨了蓄水起始时间,最低运行水位的确定等水位控制方式中的两个关键性问题,并以该成果为基础,得到了不同来水频率下的优化水库水位控制方式,所得结论可为雅砻江下游梯级水库实际运行中调度方案的制定提供参考.
Cascade reservoirs combined operation of the reservoir water level control is an important issue to give full play to the comprehensive economic benefits of cascade reservoirs, especially for large cascade reservoirs with strong regulation ability, cascade reservoir storage water level combined and reasonable water level control mode The effectiveness and effectiveness of cascade hydropower stations determine the comprehensive benefits of the cascaded hydropower station.Taking the Cascade Reservoirs downstream of the Yalong River as an example, an optimal scheduling model for cascade reservoirs is established, and a double-step optimization calculation method is proposed and used to discuss the effects of initial impoundment Time and minimum operating water level. Based on the result, the optimal reservoir water level control mode under different incoming frequency was obtained. The conclusion can be obtained from the cascade reservoir in the downstream of Yalong River The actual operation of the scheduling program to provide a reference.
