Abstract
In order to give full play to the power generation benefits of the Three Gorges Project, this paper based on the concept of floodwater utilization, studied the flood control modes of the Three Gorges Reservoir in flood season by combining the hydrological forecast in the middle and upper reaches of the Yangtze River. The benefit and risk of flood resource utilization was compared. The results show that through the implementation of flood control and utilization scheduling of the Three Gorges Reservoir in flood season, under the controllable of flood risk, the power generating capacity of the Three Gorges Reservoir in flood season can be increased by 933 million kW · h, and power generation overflow decreased 4.1 billion m3 per year, which can effectively raising the power generation benefit of the Three Gorges Reservoir and providing important technical support for the scientific dispatch of the Three Gorges Reservoir.
