摘　　要：针对确定性水库优化调度模型难以直接应用于实际操作的局限性,建立雅砻江流域“三库七级”梯级水库电站联合优化调度模型,采用Gaussian径向基函数提取各水库的调度规则,并率定和检验拟合效果。结果表明,雅砻江梯级水库电站联合优化调度运行的年均发电量为983.19亿kW·h,比设计多年平均发电量增加78.94亿kW·h(+8.73%);两河口、锦屏I级和二滩水库的优化调度过程呈现一定规律,Gaussian径向基函数拟合调度过程的决定系数R2均大于90%,能有效拟合其调度规则,且模拟调度结果相比设计值增发电量51.27亿kW·h(+5.67%)。A deterministic model of reservoir optimal operation is usually difficult to be directly applied to practical operation.To improve applicability,we develop a new joint optimal operation model for the Yalong River cascade reservoirs and use the Gaussian radial basis function(RBF)to extract operation rules,and then calibrate the rule and verify its fitting errors.The results show the annual power generation of the cascade is increased by 98.32 billion kW·h or an increase of 8.73%compared with its design value.The new operation processes optimized by the model for the Lianghekou,Jinping I and Ertan reservoirs follow certain common patterns.The determination coefficient of Gaussian RBFs is larger than 90%,and it can fit the operation rules effectively.This achieves a simulated power generation greater than the design value by 51.27 billion kW·h(+5.67%).
