Abstract
A clearance monitoring system of a wind turbine, and a monitoring method and device are provided. The clearance monitoring system includes a processor and a millimeter wave radar in communication connection to the processor. The millimeter wave radar is installed on a left side portion of a nacelle of the wind turbine. The millimeter wave radar points to a movement area of the impeller and is used for monitoring movement data of each blade on the impeller in the movement area. The processor is used to receive the movement data. According to the movement data, blade clearance between each blade and a tower of the wind turbine is determined.
