With the widespread application of onshore wind power in low wind speed areas, the efficiency of the blade aerodynamic shape of traditional wind turbines under low wind speed conditions can no longer meet the power generation requirements. This study proposes an improvement scheme for the blade aerodynamic shape. By optimizing the blade shape and adjusting the aerodynamic performance, the power generation efficiency under low wind speeds is improved. Aiming at the working environment of wind turbines in low wind speed areas, this paper verifies the gain effect of the improved blade design in a low wind speed environment through computational fluid dynamics (CFD) simulation and analysis of the actual working data of wind turbines. The improved blade aerodynamic shape can effectively increase the power generation of wind turbines under low wind speeds and enhance their overall economic benefits. This study provides new ideas and methods for the optimized design of the wind power industry in low wind speed areas.
