Dynamic and Static Visual Inspection Measurements.
Case study: Dynamic and Static Visual Inspection Measurements.
Key facts regarding relative blade pitch misalignment:
Key benefits from correcting relative dynamic blade pitch misalignment:
In order to detect relative blade pitch misalignment between the wind turbine blades, visual inspections of the wind turbine are performed while in operation (Dynamic) and in still stand (Static). The captured images are then filtered and analysed, using different methods.
The camera set-up is located on the ground, targeting on the wind turbine blades. For the static measurement the camera is located at 6 o’clock rotor position, while for the dynamic measurement the camera is located at 4 o’ clock rotor position, in order to avoid the tower influence while the blade is passing from it.
