  • System, device, and method for acoustic and visual monitoring of a wind turbine
    Patent number: 8041540
    Abstract: A method for monitoring a wind turbine. A monitoring signal, including an audio signal and/or an image signal, is received from a monitoring device. Operating data are calculated based on the received monitoring signal. An operating condition and/or a deviation is determined by comparing the operating data to baseline data.
    Type: Grant
    Filed: December 9, 2009
    Date of Patent: October 18, 2011
    Assignee: General Electric Company
    Inventors: Lutz Kerber, Florian Doorenspleet
  • Tonal emission control for wind turbines
    Patent number: 8021110
    Abstract: A system for the noise reduction of wind turbines comprises at least one acoustic sensor provided at the wind turbine, a detection unit and a control unit, wherein said detection unit is adapted to detect tonal components in a signal of said sensor, and wherein said control unit is adapted to control wind turbine operating parameters in dependence of an amplitude of a tonal component.
