摘要： A method and device for determining a tower clearance of a wind turbine. The method comprises: acquiring an image of a wind turbine in operation (S10), the image comprising the tips of blades (2) and a tower (1) of the wind turbine; determining the positions of the tips of the blades (2) of the wind turbine in the image acquired (S20); identifying the edges of the tower (1) in the image acquired (30); and calculating, on the basis of the positions of the tips of the blades (2) and the edges of the tower (1) that have been determined, the distance from the tips (2) of the blades (2) to the edges of the tower (1) to acquire a tower clearance (S40). The employment of the method and device for determining the tower clearance for the wind turbine allows the real-time determination of the tower clearance for the wind turbine, thus effectively preventing the blades (2) from hitting the tower.

摘要： A tower clearance real-time monitoring system (100) and a method therefor. The tower clearance monitoring system (100) comprises an image capture device (101), a blade position processing device (102) and a core algorithm processing device (103). The image capture device (101) 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 (102) is used to determine whether the captured image represents valid data so as to send valid data to the core algorithm processing device (103). The core algorithm processing device (103) 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 (104) of a wind turbine.
