Abstract
A system and method are provided for determining deflection of a tower of a wind turbine, the wind turbine including a nacelle with a machine head and a rotor atop of the tower. A fixed location relative to the tower is established, and a total deflection of a geographic location (“geo-location”) of the fixed location is determined. Components of the total deflection are determined that are generated by non-thrust loads acting on the tower. The non-thrust loads deflection components are subtracted from the total deflection to determine a thrust loads deflection component corresponding to deflection of the tower from operational thrust loads on the rotor.
