%X 以雅砻江中下游河段的两河口、杨房沟、锦屏I级、锦屏II级、官地、二滩和桐子林等7座梯级水库为研究对象，建立雅砻江梯级水库联合优化调度模型，并采用DPSA-POA算法求解。利用1956年6月~2013年5月的旬径流资料进行优化调度和对比分析。结果表明：与单库运行相比较，梯级水库联合优化调度运行的年均发电量可达936.96亿kW？h，提高发电量75.06亿kW？h (+8.7%)；年均弃水量为373.67亿m<sup>3</sup>，减少弃水135.74亿m<sup>3</sup> (？26.6%)；二滩和锦屏I级水库作为中、下游河段的龙头水库，具有明显的梯级水库库容补偿效益。<br />
Taking the Lianghekou, Yangfanggou, Jinping-I, Jinping-II, Guandi, Ertan and Tongzilin cascade reser-voirs in the middle and down Yalong River basin as the case study, a joint optimal operation model of cascade reservoirs was established and solved by DPSA-POA algorithm with ten-day runoff data from June 1956 to May 2013. Compared with single reservoir operation, the joint operation of cascade reservoirs can generate 93.696 billion kW？h hydropower annually, which is increased 7.506 billion kW？h (or +8.7%); the average annual abandoned water volume is 37.367 billion m<sup>3</sup>, which is reduced by 13.574 billion m<sup>3</sup> (or ？26.6%). Ertan and Jinping-I reservoirs located in the middle and down river have obvious storage compensation benefit.
