| description | In this study, the Minjiang River Basin is selected as the research object, and the construction and operation of Shuangjiangkou Hydropower Station is taken as the time division basis, the SWAT hydrological model and the joint operation model of reservoir groups are constructed, and the impact of Shuangjiangkou Hydropower Station on the downstream cascade reservoir mass generation and shipping is compared and analyzed. The results show that after the operation of Shuangjiangkou Hydropower Station, the inflow flow of the downstream cascade power station has increased significantly, and the beneficial storage capacity of the reservoir has been effectively increased. The average power generation of the target reservoir group increased by 5.059 billion kW·h in the low water period each year, of which the average power generation of Shuangjiangkou reservoir during the low water period was 2.036 billion kW·h, and the economic benefit increased by more than 1.6 billion yuan. The average annual power generation of the target reservoir group has increased by 13.958 billion kW·h, of which the average annual power generation of Shuangjiangkou reservoir is 10.869 billion kW·h, and the economic benefit has increased by more than 4 billion yuan. In addition, the shipping flow of Minjiang High Terminal also increased under different guarantee rates: 15.48% under 90% guarantee rate, 13.11% under 95% guarantee rate, and 7.74% under 98% guarantee rate. The research results provide important decision support and theoretical guidance for the joint operation and navigation optimization of large reservoirs in low water period. |
