Wind turbines operating in cold and moist climates often suffer from icing events. Ice accretion on wind turbine blades threatens safe operation of wind turbines. Additionally, this phenomenon results in deterioration in power performance, which undoubtedly leads to economic losses. Ultrasonic guided wave anti-/de-icing technology has advantages of low energy consumption, light weight and low cost...
This paper proposes a non-thermal method for wind turbine blade de-icing. A lead-free lithium niobate compound is based to fabricate a light ultrasonic transducer as such material has a high Curie temperature of 1210 °C, compared with the commonly used piezoelectric ceramics (PZT). The detail of fabricating the transducer is provided, which includes an examination of the critical properties of the...
