ABSTRACT:
A system for estimating a freestream wind characteristic for a wind turbine having a rotor includes estimating a nacelle wind speed for the turbine; determining, from the estimated nacelle wind speed, at least one angular position of the rotor for measuring a nacelle wind characteristic for the turbine; and measuring the nacelle wind characteristic at the determined angular position of the rotor.
