Outline
In freezing and icing environment, the field tests of 2 MW wind turbine blades by aerothermal antiicing/deicing method is carried out to verify the antiicing/deicing effect and energy consumption. Firstly, this paper analyzes the complex process of blade surface icing and then its icing distribution on the surface of NACA64618 airfoil is simulated. Secondly, the blade active aerothermal antiicing/deicing system for 2 MW wind turbine is constructed in the field demonstration project. Finally, three tests are finished with the help of the panoramic infrared thermal imaging detection, including the static deicing test, static antiicing test and production test with antiicing, and then evaluate blade antiicing/deicing effect and heating energy consumption. The test results show that the blade surface begins to melt and fall off after continuous heating for 2 hours when the ice thickness is 30 mm and the heating control temperature is 50 °C, and the heating energy consumption power is less than 50 kW, which can provide a reference for the design of engineering application system of aerothermal antiicing and deicing of wind turbine blade.
