摘　　要：为分析南水北调西线工程上下线组合调水方案和下线调水方案对洮河梯级水电站发电影响,分别针对南水北调西线工程不同调水方案、不同调水模式,研究对洮河干流梯级水电站扩机、发电等的影响。结果表明:南水北调西线工程调水可大幅增加洮河梯级水电发电效益,其中,基于下线调水方案的增加值约为上下线组合调水方案的2倍,而丰多枯少调水模式对洮河梯级水电增加效益小于均匀调水模式。The Western Route of South-to-North Water Transfers Project is a major strategic infrastructure in the national"four horizontal and three vertical"water resources allocation pattern,diverting water from the upper reaches of the Yangtze River into the Yellow River.In 2020,the Comparison and Demonstration of Planning Schemes for the Western Route of South-to-North Water Transfers Project was examined and approved by the General Institute of Water Planning of the Ministry of Water Resources,and following schemes were formulated:the upper route(UR),the upper and lower combination routes(ULR),and the lower route scheme(LR).The water diversion for the first phase of the Western Route Project is 8 billion m^(3).Two water transfer processes were set up in each scheme to study the influence on power generation of the cascade hydropower stations in Taohe River based on the ULR and the LR schemes.At the same time a maximum power generation scheduling model and a guaranteed output calculation model of cascade hydropower stations were constructed.The two-layer improved invasive weeds optimization(TIIWO)algorithm was used to solve the above models.Meanwhile,a method for assessing the expansion potential of the cascade hydropower stations was proposed.The results showed that the expansion potential of cascade hydropower stations in the Taohe River was greatly enhanced by the first phase of the Western Route Project.The installed scale of the cascade hydropower stations in the Taohe River was increased to 1,128.62 MW and 1,642.12 MW,respectively,by the ULR and the LR schemes in the uniform water diversion mode,and to 1,109.12 MW and 1,603.62 MW respectively,by the rich and poor water diversion mode without altering the installed utilization hours of the hydropower stations.Considering the expansion potential of the cascade hydropower stations in the first phase of the West Route Project,the power generation of the cascade hydropower stations in the Taohe River was increased by 105.13%and 194.87%by the ULR and the LR schemes,and
