  • Vibration damping method for variable speed wind turbines
    Patent number: 7423352
    Abstract: A vibration damping technique for a wind turbine system is described. The wind turbine system includes a vibration damper, which provides a variable signal to control torque produced by a generator of the wind turbine system. The variable signal is based on generator speed and has a first local peak value based on a resonant frequency of tower side-to-side oscillation.
    Type: Grant
    Filed: November 15, 2007
    Date of Patent: September 9, 2008
    Assignee: General Electric Company
    Inventors: Shashikanth Suryanarayanan, Aaron Avagliano, Corneliu Barbu

  • System and method for upwind speed based control of a wind turbine
    Patent number: 7342323
    Abstract: A method for controlling power output of a wind turbine generator in response to an anticipated change in wind speed is provided. The method includes sensing wind speed at a desired distance from the wind turbine generator in a direction of the wind. The method further includes controlling pitch of a blade of the wind turbine generator based upon sensed transient wind speed in advance of a change in wind speed at the wind turbine generator.
