  • Method for controlling an electrical generator of a wind turbine
    Patent number: 12603591
    Abstract: The present disclosure relates to a method for controlling an electrical generator of a wind turbine, the generator having a rotor and a stator, and the stator being controlled by a stator current. The stator current has a main component being characterized by a fundamental signal with a fundamental frequency and a fundamental phase angle, and a fractional harmonic current component being characterized by a fractional harmonic signal having a fractional harmonic frequency and a fractional harmonic phase angle. The method includes providing a compensation current having a compensation amplitude and a compensation phase angle, and determining the compensation phase angle depending on an absolute rotational position of the rotor.
