As power station dispatching faces higher comprehensive utilization requirements, power generation benefit cannot be ignored for river basins with navigation and ecology requirements. In this paper, the Shuibuya Hydropower Station is adopted as the engineering background, and a multi-objective optimization model with power generation, navigation and ecology as the objectives is constructed. The RSEA algorithm is adopted to obtain a scheme set. By comparing the typical schemes, changes in power generation have less impact on navigation and ecology. The optimized benefits can be sacrificed at the expense of a small part of the power generation. In the model calculation, a large weight coefficient should be allocated to the power generation, and the optimal solution set is still obtained. The result can provide reference for how to balance multi-target weight coefficients of similar hydropower stations.
