Icing seriously affects the operation of wind turbines, constraining the development of the global wind power industry. However, the existing anti-icing methods cannot meet the demand for speed and low consumption. This work proposes electric-impulse de-icing method for wind turbine blades and carries out the electric-impulse de-icing experimental research of 2mm, 5mm, 10mm icing in the artificial climate chamber. After multiple electric-impulse de-icing cycles, the de-icing of 2 to 10 mm glaze can be achieved, and within 1 minute, the de-icing of an area of nearly 6000 cm2 on the surface can be completed (with an average de-icing power consumption of 66W). The feasibility of the electric-impulse de-icing method for wind turbine blades has been verified, which helps to further enhance the ice accretion defense capability of wind turbine blades in high humidity and low-temperature environments.
