  • Controlling a wind turbine converter
    Patent number: 12027868
    Abstract: Provided is a method of controlling a converter, in particular of a wind turbine, the converter including a first converter portion connected to a generator, a DC-link, and a second converter portion connected to a utility grid. The method including: controlling the first converter portion and the second converter portion by a first control signal and a second control signal, respectively, both being derived based on a requested power signal, in particular requested active power signal, and a generator rotational speed, wherein the first control signal indicates substantially constant generator torque for rotational speed variations of the generator rotational speed above a frequency threshold.
