摘要: 乐昌峡水库原设计从10月1日开始蓄水，导致水库蓄满率很低。本文根据水库蓄水调度控制线，计算蓄水期分期设计洪水和防洪控制水位，建立多目标水库优化蓄水调度模型，并采用NSGA-II算法求解。结果表明：在防洪限制水位的约束下，蓄水时间越提前，水库的综合利用效益越大。与原设计方案相比，8月1日和9月1日起蓄方案蓄水期发电量分别提高了21.62%和13.49%，蓄满率分别提高了10.40%和9.96%，多年平均蓄水量分别增加了4979和3647万m³。在确保防洪安全的前提下确定关键时间节点及对应水位，可为提前蓄水调度提供技术参考。
Abstract: The designed impoundment scheme of Lechang reservoir was started in October 1, which results in a low impoundment efficiency. In this study, the seasonal design floods and flood control limited water level during the impounding period were calculated. Based on the reservoir impoundment operation lines, a multi-objective operation model was established and solved by the NSGA-II algorithm. Compared with the designed impoundment scheme, the advance impoundment scheme for August 1 (or September 1) can increase 21.62% (or 13.49%) power generation, 10.40% (or 9.96%) total impoundment efficiency, and 4979 (or 3647) million m³ water resources, respectively. Determining key time nodes and corresponding water levels can provide technical reference for advance impoundment operation on the premise of ensuring flood control safety.
