Abstract

A wind turbine blade deicing system and a control method therefor. The wind turbine blade deicing system comprises temperature sensors, a control component, and deicing components; a temperature sensor is arranged in each blade; a deicing component is arranged in each blade; the control component receives signals from the temperature sensors and can separately control the deicing component in each blade. The control method comprises a time-sharing cycle control method and a time-sharing area-based control method for blade heating, and a limit temperature protection strategy for blades. The system and the control method therefor can reduce the instantaneous electric power during blade heating, reduce the design requirements for a slip ring, and improve the deicing efficiency.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a wind power blade deicing system and a control method thereof. Background technique [0002] Wind power generation is a wind power method that converts the kinetic energy of wind into electrical energy. In places where the air temperature drops or the humidity is high, the fan blades often frost and freeze. When a large number of blades freeze, the efficiency of the fan will be reduced, the output power of the unit will be reduced, and the operation safety of the power grid system will be affected. Therefore, it is of great significance to the stable operation of the wind power generation system to be able to detect the icing of the fan blades in time and effectively, and to remove the ice in time. [0003] At present, the existing active deicing technologies for wind turbine blades are mainly divided into gas-thermal, electric-thermal, and gas-electric combinati...
