摘　　要：随着乌东德、白鹤滩水库的相继蓄水,金沙江下游-三峡梯级水库联合调度模式逐渐由四库向六库转变,相应梯级水库联合调度策略将发生变化。将水库全年调度时期划分为消落期、汛期、蓄水期,对近5 a不同调度时期溪向-三葛梯级四库调度策略进行总结分析,就金沙江-三峡梯级六库联合调度策略进行研究。结果表明:梯级水库在不同调度时期的调度任务和调度策略不尽相同。随着四库到六库的转变,各个调度时期,在完成调度任务的前提下,调度策略均需要发生一定的转变。研究成果可为后续梯级六库全面联合调度做铺垫。With the successive impoundment of Wudongde and Baihetan reservoirs, the joint operation mode of the cascade reservoirs from lower Jinsha River to Three Gorges reach is gradually changing from 4 reservoirs to 6 reservoirs, so the corresponding joint operation strategy of cascade reservoirs will change.The whole operation year of the reservoir was divided into drawdown period, flood season and impounding period.The operation strategy of Xiluodu Reseroivr-Xiangjiaba Reservoir and Three Gorges Reservoir-Gezhouba Reservoir cascade in different operation periods in recent 5 years was summarized and analyzed, and the joint operation strategy of 6 cascade reservoirs from lower Jinsha River to Three Gorges reach was studied.The results showed that the operation tasks and strategies of cascade reservoirs were different from operation periods.With the transformation from 4 reservoirs to 6 reservoirs, the operation strategy needs to change in each scheduling period on the premise of completing the scheduling task.The research results can pave the way for the comprehensive joint operation of the cascade of 6 reservoirs.
