中文摘要：

引汉济渭调水工程是缓解关中地区缺水，改善渭河生态的重要措施之一。黄金峡、三河口水库群、泵站群的调水模式直接决定了工程总调水量和调水效益。以多年平均调水15亿m^3为目标，设置“黄金峡水库先调水三河口水库补充调水”和“三河口水库先调水黄金峡水库补充调水”两种调水模式。通过长序列计算，对比不同调水模式下总调水量、泵站耗能和电站发电量等各项评价指标。研究结果表明：在“黄金峡水库先调水三河口水库补充调水”的情况下，引汉济渭工程可调水量15．55亿m^3，梯级总发电量5．53亿kw·h，梯级总耗电量4．91亿kW·h，净发电量为正值；在“三河口水库先调水黄金峡水库补充调水”的情况下，引汉济渭工程可调水量14．45亿m^3，梯级总发电量6．24亿kW·h，梯级总耗电量10．86亿kW·h，净发电量为负值。研究结果对于引汉济渭工程的调度具有重要参考价值。

英文摘要：

Hanjiang-to-Weihe River Valley Water Diversion Project is one of the important measures to alleviate the water short- age in Guanzhong Area and improve the ecology of Weihe River. The total water transfer amount and the water transfer benefit of the project are directly decided by the water transfer modes of Huangjinxia and Sanhekou reservoir group and pumping station group. Taking the yearly average water transfer amount of 1.5 billion m3 as the target, two water transfer modes, i. e. transferring water from Huangjinxia Reservoir at first and then additionally transferring water from Sanhekou Reservoir, and transferring water from Sanhekou Reservoir and then additionally transferring water from Huangjinxia Reservoir, are made up. Through a long series calculation, the evaluation indexes of all the items of the total water transfer amount, energy consumption of pumping station, power generation of hydropower station, etc. under different water transfer modes are compared. The study result shows that un- der the operation condition of transferring water from Huangjinxia Reservoir at first and then additionally transferring water from Sanhekou Reservoir, the water amount of 1. 555 billion m^3 can be transferred through Hanjiang-to-Weihe River Valley Water Diversion Project with the total cascade power generation of 0. 553 billion kW·h and the total cascade energy consumption of 0. 491 billion kW·h, for which the net power generation is positive, while under the operation condition of transferring water from San-hekou Reservoir and then additionally transferring water from Huangjinxia Reservoir, the water amount of 1. 445 billion m^3 can be transferred through Hanjiang-to-Weihe River Valley Water Diversion Project with the total cascade power generation of 0. 624 billion kW·h and the total cascade energy consumption of 1. 086 billion kW·h, for which the net power generation is nega- tive. The study result has an important reference value for the operation of Hanjiang-to-Weihe River Valley Water Diversion Project
