In this dissertation, the rotor harmonic response recorded by sensors already installed on wind turbines is further exploited to develop two new methodologies. The first one estimates the ambient wind conditions, in terms of vertical and horizontal shears and misalignments, starting from blade bending moments, while the second detects and remotely corrects for rotor imbalances using main bearing accelerations. Both methods were successfully validated with synthetic and wind tunnel data. In addition, a first field validation of the wind sensing technology is also presented.
