摘　　要：对三峡梯级和清江梯级组成的混联式水电站群进行联合优化调度研究,建立了以梯级发电量最大为目标的水电站群联合调度模型,采用POA方法计算两个梯级单独运行和梯级联合调度时电量补偿效益。结果表明,丰、平、枯三个典型年的年电量分别增加了15.14亿、17.25亿、4.41亿kW·h,两梯级联合优化调度在提高非汛期发电量、减少主汛期弃水量等方面效益明显,联合运行对清江梯级的电能补偿效益更为显著。The joint operation of the Three Gorges cascade and Qingjiang cascade reservoirs was studied in this paper. Choosing maximum hydropower generation as objective function, an optimal model was established for individual or joint operation of cascade reservoirs. The Progressive Optimality Algorithm was applied to calculate the electricity compensation benefits for the individual and joint operation of two cascades. The research results showed that the annual electricity amount in three typical hydrologic years, i,e. wet, normal and dry year, increases 1.514, 1.725 and 0.441 billion kWh respectively. The joint optimal dispatching of two cascades could obviously enhance power generation during non-flood season and decrease water escape amount during main flood reason. The compensation benefit of the Qingjiang cascade is more significant.
