Experimental Study on Electro-Impulse De-Icing of Wind Turbine Blades

Wind turbine blades may be ice-covered in winter, which may lead to wind farm outage, resulting in huge social impact and economic damage. At present, there are few technologies and experiences on de-icing of wind turbine blades at home and abroad. According to the characteristics of the fan blade, this paper proposes an electric pulse de-icing method, winding the distributed pulse coil of electric pulse de-icing, and obtaining the reasonable winding of the coil through the measurement and analysis of the coil current waveform. Using COMSOL software to conduct electrodynamic simulation analysis on the aluminum plate, the distribution of the impulse force is obtained. Through the simulation test of the artificial climate chamber, it is shown that the electric pulse technology can effectively remove the ice of the contact rail through the reasonable parameter coordination, and it has the characteristics of fast deicing speed, high efficiency and low energy consumption.
