Abstract

See full text

A method for operating a wind turbine determines reliability of an azimuth measurement system by measuring loads with load sensors during operation of the wind turbine. Based on the measured loads, in-plane moments generated on the blades at a rotational speed frequency of the rotor are determined. The azimuth measurement system has reduced reliability if the angular phase of the in-plane moments at the rotor rotational speed frequency of the rotor deviates from an angular phase measured by the azimuth measurement system by more than a first threshold value. The method generates a warning signal or changes operation of the wind turbine when it is determined that the azimuth measurement system has reduced reliability.
