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) foor both the detection and the verification measurements. The captured images are then filtered and analysed, using different methods. The camera set-up is placed on the ground, targeting on the wind turbine blades. In addition, it is located at 4 o’ clock rotor position, in order to avoid the tower influence while the blade is passing from it.
Detection dynamic measurement
Verification dynamic measurement
This is visual confirmation of the significant importance of relative blade pitch misalignment detection & successful correction for
achieving the desired aerodynamic rotor balance.
