ABSTRACT:
Certain embodiments of the invention may include systems and methods for testing a wind turbine pitch control system. According to an exemplary embodiment of the invention, a method for testing a wind turbine pitch control system is provided. The method can include measuring tangential acceleration (At) of a wind turbine rotor, determining pitch angle of one or more turbine blades, and predicting torque applied to the one or more turbine blades based at least in part on the tangential acceleration (At) and the pitch angle.
