Advanced sensor for optimal orientation and predictive maintenance of high power wind generators

In this paper, a smart sensor for optimal orientation and predictive maintenance of high-power wind generator insensible to turbulent air flux is showed, which enables measurement of the incident wind direction and energetic transformation efficiency. In addition, it analyses characteristic parameters concerning to structural stresses useful for maintenance tasks. This new patented sensor (PCT n/spl deg/. 200100142) extracts the suitable information from the structural deformation caused by the effect of the wind over the blades. This deformation is function of the incident wind direction, force or velocity, as well as the vibration modes of the structure.
