Title:
DETECTION METHOD AND DEVICE FOR BLADE BALANCE OF WIND TURBINE
Document Type and Number:
WIPO Patent Application WO/2023/272969
Kind Code:
A1
Abstract:
A detection method and a detection device for blade balance of a wind turbine, a readable storage medium, and a computing device. The detection method comprises: acquiring an image captured by a sliding rail camera installed at the bottom of a tower of a wind turbine; determining tower identification points of the wind turbine in the captured image on the basis of parameters of the image and physical parameters of the wind turbine; determining a static clearance distance of the wind turbine on the basis of the tower identification points; and detecting, according to the static clearance distance, whether blades of the wind turbine are in a balanced state. According to the detection method, the detection device, the readable storage medium and the computing device, by accurately determining the static clearance distance, the consistency of blade installation can be determined after blade hoisting is completed, and the wear of the blades can be confirmed during re-inspection of the wind turbine, thereby avoiding safety accidents caused by blade imbalance.
