Optimization of Operating Water Level of Wuqiangxi Reservoir in Main Flood Season Based on Forecast and Pre-discharge
Optimizing the dispatching mode during flood season is a crucial step in enhancing the comprehensive benefits of Wuqiangxi Reservoir.On the premise of ensuring flood control safety,we employed the method of fore-cast and pre-discharge to investigate the range and starting conditions for dynamic control of water level,and the operation mode of pre-discharge for Wuqiangxi Reservoir during the main flood season.Additionally,we calculated the comprehensive benefits of uplifting operational water level in flood season.Case studies on the flood season oper-ations in 1996 and 2019 demonstrate that dynamic control of operating water level during flood season increased power generation head by 0.48 and 0.54 meters,reduced wasted water by 853 million and 956 million cubic me-ters,and boosted power generation by 126 million and 134 million kW·h,respectively.The results indicate that under controllable risk conditions,dynamic control of operating water level in Wuqiangxi Reservoir during flood season significantly improves power generation efficiency while reducing the likelihood of unit output blockage and water waste.
