Wind turbine anemometry compensation

摘要

A method (50) of estimating a freestream wind characteristic for a wind turbine (2) having a rotor (8) is disclosed. The method includes estimating a nacelle wind speed for the turbine; determining, from the estimated nacelle wind speed, at least one angular position of the rotor (8) for measuring a nacelle wind characteristic for the turbine; and measuring the nacelle wind characteristic at the determined angular position of the rotor.
