The image capture device () is used to capture an image of a wind turbine in an operating state, and the image comprises a blade portion and a tower portion; The blade position processing device () is used to determine whether the captured image represents valid data so as to send valid data to the core algorithm processing device (). The core algorithm processing device () is used to use valid data to calculate a tower clearance value for a blade, and to send a calculation result to a wind turbine main control system () of a wind turbine.

Tower clearance monitoring system and method therefor

Methods, apparatuses, and systems for collecting the installation error of the wind vane are provided. The image of the blades of the wind turbine and the outer rotor of the generator is obtained. It is determined whether the wind vane is aligned with the center line of the wind turbine, according to a relationship between the center line of the wind turbine and the orienting plane of the wind vane in the image. In a case that the wind vane is not aligned with the center line of the wind turbine, the deviation angle between the wind vane and the center line of the wind turbine is calculated, and a direction of the wind vane is corrected according to the deviation angle. Therefore, installation errors of the wind vane are accurately determined and corrected, and accuracy is improved for installation of the wind vane.
