In order to study the effects of icing on the aerodynamic performance of airfoils and the power generation performance of wind turbines, CFD (computational fluid dynamics) is used in this paper to simulate and analyze the airfoil before and after icing based on the numerical simulation of a NACA airfoil. Results of the analysis show that ice accretion on the airfoil causes the lift coefficient to decrease and the drag coefficient to increase, which results in a significant deterioration in the aerodynamic performance of the airfoil. To further verify the analysis results, real-time icing monitoring is carried out on a 1.5MW wind farm. Statistics show that after ice accretes on the blades, the power curve of the blades decreases overall, and the blades stall at a speed close to the rated wind speed.
