  • Control method, program and system for controlling the bearing preload of a wind turbine and wind turbine comprising such control system
    Patent number: 10215227
    Abstract: A control method configured to control the preload of a bearing includes estimating the preload on the bearing; comparing the estimated preload with a predetermined acceptance range; and correcting the preload on the bearing when the preload is outside the acceptance range.
    Type: Grant
    Filed: August 6, 2013
    Date of Patent: February 26, 2019
    Assignee: WINDFIN B.V.
    Inventors: Matteo Casazza, Thomas Kaessner

  • WIND POWER TURBINE AND WIND POWER TURBINE CONTROL METHOD
    Publication number: 20140356162
    Abstract: A wind power turbine control method, the wind power turbine having an electric machine, in turn having a stator, a rotor rotatable about an axis of rotation with respect to the stator, and a mechanical bearing assembly configured to couple the rotor in rotary manner to the stator; the stator having at least one winding to interact electromagnetically with the rotor; and the control method including the steps of: estimating at least one quantity selected from a group including a distance between the rotor and the stator, the variation over time in the distance, and misalignment between the rotor and stator; defining a localized additional magnetic force as a function of the selected quantity; and regulating the selected quantity using the localized additional magnetic force defined.
