摘要
梯级水库联合调度规律是指导梯级水库优化运行的重要手段,目前尚无完整的梯级水库群调度规律的理论体系。为此,提出一种可获取梯级水库群联合调度规律的改进调度函数方法,并应用逐步回归法对调度函数进行拟合及相关因子的选择。以乌江流域梯级水库群为例,开展其联合调度研究。结果表明,该方法计算结果较原设计方案,多年平均发电量比设计值增加了14.43亿kW·h,涨幅达5%,保证出力提高到2 431.9 MW,经济效益显著。
The cascade reservoir joint operation rules are an important mean to guide the optimal operation of cascade reservoirs. At present, there is not a complete theory system for cascade reservoir joint operation rules. An improved operation function method is proposed herein to obtain the rules, in which, the stepwise regression function is used to fit operation function and choose relevant factors. Taking Wujiang cascade reservoirs as study case, the cascade reservoir joint operation is studied. Comparing with original scheme, the new joint operation rule can increase average annual energy output of 1.443 billion kW.h or 5% and guaranteed output to 2 431.9 MW.
