| Zusammenfassung: | The invention belongs to the technical field of wind power generation, and particularly relates to a monitoring system and a monitoring method for preventing a blade from sweeping a tower. Segmenting the blade, measuring the deformation of each segment of the blade, comparing the deformation with the initial shape to obtain the deformation of each segment, and adding the deformation of each segment to obtain the total deformation of the blade; according to the deformation of each section and the comparison between the total deformation and the initial shape of the blade, the deformation of each section of the blade, the clearance distance of the whole blade and the clearance distance change rate are calculated, the clearance distance change rate is the change speed of the clearance distance in unit time, and the clearance distance refers to the vertical distance from the blade tip to the tower drum; the operation mode of the fan is controlled according to the clearance distance and the clearance distance chan |
