Abstract

The invention belongs to the technical field of wind turbine inspection and relates to an inspection method and system for a wind turbine. The inspection method of the wind turbine comprises the following steps that: the first point cloud set of the surface of the wind impeller of the wind turbine is collected; the space position model of the blades of the impeller is calculated according to the first point cloud set; the first boundary lines of an unmanned aerial vehicle pre-flight area path are calculated according to the space position model of the blades of the impeller, wherein the boundary lines comprise an inner boundary line and an outer boundary line; the unmanned aerial vehicle pre-flight area path is determined according to the inner boundary line and the outer boundary line; and an unmanned aerial vehicle performs inspection according to the unmanned aerial vehicle pre-flight area path. The inspection system of the wind turbine comprises a visual range finder, a monitoringunit, a data processing unit and an unmanned aerial vehicle control unit. With the inspection method and system for the wind turbine of the invention adopted, the crack and expansion conditions of theblades can be accurately judged, and accidents are avoided.

Description

technical field [0001] The invention relates to the technical field of wind turbine inspection, in particular to a wind turbine inspection method and system. Background technique [0002] The blade is the most basic and critical part of the wind turbine, and its good design, reliable quality and superior performance are the decisive factors to ensure the normal and stable operation of the unit. Because the whole is exposed outside and the working conditions are harsh, accidents of blade loss and failure occur from time to time. When a blade failure accident occurs, especially a single-piece fracture accident, the balanced rotation state of the three blades is destroyed, and the generator set vibrates violently instantly; hazard, and may cause the entire unit to burn. [0003] Therefore, it is necessary to conduct regular inspections on the blades, find defects in time, take effective measures to eliminate or prevent the expansion of defects, and eliminate accidents in the ...
