Design of deicing device for wind turbine blade based on microwave and ultrasonic wave

Abstract

Nowadays, wind turbine deicing has become a hot research topic. The traditional deicing method of blade has many problems, such as high energy consumption, low efficiency and low effect. In order to solve the above problems, the project team designed a wind turbine blade deicing device based on microwave and ultrasonic wave. During the operation, two deicing methods, namely microwave thermal energy, ultrasonic cavitation effect and thermal effect, were used to deice in stages to achieve the purpose of high efficiency and energy saving. The whole device is composed of walking system, microwave system and ultrasonic system, and the operation of the device is realized by the electrical control part. Compared with the existing deicing methods, the device can achieve the purpose of low energy consumption and high efficiency Deicing; in addition, the device has the advantages of flexible mechanism for control, less pressure on wind turbine blades, and low cost.
