| Abstract: |
| Wind energy resources are very rich in high-altitude the plateaus and cold regions.It is easy for ice to form on the blade surface of wind turbines in this region.In order to solve the ice-covering problem of wind turbine blades in cold regions,the ice-covering mechanism and the main influencing parameters are defined in this paper firstly.Based on numerical simulation,the effects of environmental factors and blade geometric parameters on blade icing under freezing rain conditions were analyzed.The results show:when the wind speed increases from 2 m/s to 4 m/s,the maximum ice thickness increases by 117%,when the wind speed increases from 4m/s to 10 m/s,the maximum ice thickness increases by 0.9%.The ice mass increases linearly with the increase of wind speed.When the wind speed is constant and the temperature drops from -1℃ to -2℃,the ice mass and the maximum ice thickness on the blade surface increase by 71% and 24%.When the temperature changes from -2℃ to -5℃,the ice mass and the maximum ice thickness increase by 1.7% and 0.9%.When the temperature and wind speed are at a fixed value,the ice mass and maximum thickness increase with the increase of relative thickness and angle of attack of the blade. |
