Description

technical field [0001] The invention relates to the field of anti-icing and deicing of wind turbines, in particular to a method for evaluating the performance of an electrothermal deicing system of a wind turbine. Background technique [0002] When a wind turbine is installed in a cold and humid area, the surface of the blades of the wind turbine will freeze. In my country, however, wind turbines are mainly installed in the northeast, north, northwest and southeast coasts, where blade freezing is very likely to occur. The icing of wind turbine blades will cause great harm to the operating efficiency of wind turbines and the safety of personnel. The icing of the blades changes the airfoil of the wind turbine blades, seriously affects the aerodynamic performance of the wind turbine, causes the wind turbine to shut down, and reduces the power generation of the wind turbine. Icing also increases the load on the wind turbine, destroys the dynamic balance of the rotating blades,...
