Abstract: Zhexi Hydropower Station is located in the Zishui River Basin,central Hunan Province,and it undertakes important task of flood control and power generation for Hunan Province.In recent years,due to the impact of global climate change,frequent rainstorms have led to water abandonment in reservoirs,and even threatened the safety of downstream flood control.At present,some researches have been carried out on rainstorm prediction,inflow and water level prediction in Zhexi Reservoir Basin,but a complete optimal operation system for flood control and power generation in Zhexi Reservoir has not yet been formed.In this paper,an optimal operation strategy for flood control and power generation of Zhexi Reservoir is proposed,which covers the analysis of long-term situation of rainstorm in the reservoir basin,the prediction of location and intensity of rainstorm,the calculation of distributed runoff generation and confluence,and the formulation of multi-objective dispatching scheme for flood control and power generation,which provides technical support for the optimal operation of flood control and power generation of Zhexi Reservoir.

Key words: optimal dispatch for flood control and power generation, rainstorm forecast, runoff generation and confluence, Zhexi Reservoir;
