The state of wind turbine blades directly affects the power generation efficiency of the wind turbine. Wind turbine blades are easy to freeze or freeze when operating in a low-temperature environment, and the icing of the blades will cause measurement errors, lead to energy loss, and cause the wind turbine to be overloaded and stop, and in severe cases, it will cause mechanical damage and electronic cable damage.
