Abstract
Certain embodiments of the invention may include systems and methods for determining an angular position of a wind turbine rotor. According to an exemplary embodiment of the invention, the method for determining an angular position of a wind turbine may include measuring tangential acceleration and radial acceleration of the rotor, measuring speed of the rotor, determining rotational tangential acceleration of the rotor based at least in part on the change of rotor speed over time, determining rotational radial acceleration based at least in part on the rotor speed, adjusting the measured tangential acceleration based at least in part on the determined rotational tangential acceleration, adjusting the measured radial acceleration based at least in part on the determined rotational radial acceleration, and determining an angular position of the rotor based at least on the adjusted tangential acceleration and the adjusted radial acceleration.
