Abstract

The transition γ-Re_θ and k-ω SST turbulence model were used to calculate aerodynamic characteristics of the airfoil with vortex generators, based on the variation of the blade airfoil angle of attack under the turbulent condition, the aerodynamic angle of attack variation pattern of the blade under quasi-steady gust conditions was analyzed, the actual power and load characteristics of wind turbine with vortex generators were investigated in different turbulence and air density conditions. The results indicate that the airfoil stall characteristic of wind turbine blades can be affected by air density, ambient turbulence and rotor speed. Vortex generators an reduce the sensitivity of air density and turbulence intensity to wind turbine blades, as well as decrease blade load and vibration in edgewise direction.
