windcomp-fig-1A Tool to Avoid Aerodynamic Imbalance

The accurate synchronisation of rotor blades is an important requirement for the optimal operation of wind turbines in relation to both generation and loads. Because of the lack of appropriate measurement devices that allow easy and timesaving inspection, the problem has long been underestimated and neglected at the same time. However, with the development of new, highly efficient wind turbines with extremely long rotor blades, misalignment has become a greater problem due to the substantial surplus loads caused by aerodynamical imbalance. The subject shifted into the focus of manufacturers and operators and caught growing interest as it applies to all wind energy converters.
