%X 随着堵河水库群完建并进入正常运行期运用，堵河流域形成了以潘口水库为核心的控制性水库群。为减少堵河流域水电站在汛末蓄水期无效弃水，提高水资源综合利用率和兴利效益，本文开展了水库汛末蓄水调度方式优化研究。首先采用K判别系数法，分析了流域梯级水库蓄水次序；进而针对来水较枯、潘口水库汛后无法蓄满的年份，提出了基于改进K判别系数法的梯级水库蓄水次序优化模型；并以蓄满率和发电指标对蓄水方案进行了评价。研究表明，改进后的梯级水库联合蓄水方案，可有效增加总发电效益约0.266亿kW·h。<br />
With the completion and being in practice of Duhe reservoir group, the operation of the key reservoirs represented by Pankou has begun to take shape. In order to reduce the ineffective water abandonment of cascade hydropower stations at the end of flood season and improve the comprehensive utilization rate of water resources, the optimal operation model of cascade reservoirs at the end of flood season is established. Firstly, the storage inlet order of cascade reservoirs is analyzed by K discrimination coefficient method. Then, for years when the incoming water flow is relatively less and Pankou Reservoir cannot be fully filled after flood season, the water storage sequence of cascade reservoirs is improved based on the K discrimination coefficient method, and the impound scheme is evaluated according to the full storage rate and power generation index. The joint operation of reservoir group can increase 26.6 million kW·h power generation annually.
