梯级水库消落运用方式是充分发挥梯级水库综合经济效益的重要课题,如何科学控制各电站枯期消落水位、兼顾梯级总发电效益并控制弃水是梯级水库枯水期联合调度的关键。本文在分析屏山水文站枯水期及汛前径流规律的基础上,探讨了金沙江梯级近期水平下溪洛渡和向家坝电站不同消落深度对总体运行调度的影响,提出5月、6月分旬控制消落的金沙江梯级水库枯期消落方案,并对不同频率来水情况下不同消落方式的发电效益进行了比较,然后,以金沙江下游乌东德、白鹤滩、溪洛渡和向家坝四库梯级电站群为研究对象,对金沙江四库联合运行时枯期消落方式进行初步研究,所得结论可供金沙江梯级水库在实际运行中制定调度方案参考。
How to control cascade reservoirs’ comprehensive economic benefits is an important issue. How to scientifically control the water level of each station during the dry period, taking into account the total power generation efficiency of cascades and the control of abandoned water are the keys to the combined operation of cascaded reservoirs. Based on the analysis of the runoff at the Pingshan hydrological station and the runoff before the flood season, this paper discusses the effect of the different runoff depths of the Xiluodu and Xiangjiaba hydropower stations on the overall operation schedule under the recent level of the Jinsha River runoff. In the lower reaches of the Jinsha River, Wudongde, Baihetan, Xiluodu and Xiangjiaba hydropower stations were compared. Siqu County cascade hydropower station as the research object, during the Jinshajiang four-bank joint run-up during the dry-up and fall of the initial study, the conclusions for the Jinsha cascade reservoir in the actual operation of the scheduling program reference.
