Problems solved by technology

Additionally, wind turbines often have to be shut down while personnel are inside the wind turbine, which reduces the production capacity of wind turbines currently undergoing inspection
[0004] Inspection of offshore wind turbines is also challenging, mainly due to the accessibility of the turbines

Embodiment Construction

[0048] In some configurations and with reference to figure 1 , the wind turbine 100 includes a nacelle 102 in which a generator (not shown in figure 1 middle). The nacelle 102 is mounted atop a tall tower 104, only a portion of which is shown in figure 1middle. Wind turbine 100 also includes a rotor 106 including one or more rotor blades 108 attached to a rotating hub 110 . although figure 1 The illustrated wind turbine 100 includes three rotor blades 108 , although the invention requires no specific limitation on the number of rotor blades 108 .

[0049] refer to figure 2 , various components are housed in nacelle 102 or in tower 104 of wind turbine 100 . The height of tower 104 is selected based on factors and conditions known in the art. In some constructions, one or more microcontrollers within the control panel 112 comprise the control system for overall system monitoring and control. Alternative distributed or centralized control structures are used in some conf...

Abstract

A method and system for inspecting a wind turbine is provided. The method includes providing at least one remotely operated aerial platform (ROAP), providing at least one non-destructive evaluation (NDE) device attached to the ROAP, and providing at least one distance measuring system attached to the ROAP. The distance measuring system is used for determining the distance between the ROAP and at least a portion of the wind turbine. The method also includes positioning the ROAP so that the at least one non-destructive evaluation device captures data used for inspecting the wind turbine.

Description

technical field [0001] The present invention generally relates to methods and systems for inspecting wind turbines. More specifically, the present invention relates to methods and systems employing remotely operated aerial platforms for inspection of wind turbines. Background technique [0002] Regular inspections of wind turbines are required to maintain their reliable and efficient operation. However, wind turbines are always damaged due to external influences (eg lightning, wind, rain, hail, etc.) or due to normal wear and tear which lead to fatigue of the various components. [0003] Inspections to the outside of the tower are difficult and large cranes are often required to provide access for critical inspection of various components such as blades. A technician can manually climb up the tower and lower it down, but this is a time consuming, labor intensive and dangerous activity. The inside of the wind turbine also needs to be inspected, and technicians must climb t...
