  • Condition monitoring system for wind turbine generator and method for operating wind turbine generator
    Patent number: 7855469
    Abstract: A method for operating a wind turbine generator includes generating at least one of a plurality of rotor shaft angular displacement values, a plurality of rotor shaft angular velocity signals, and a plurality of rotor shaft angular acceleration signals. The method also includes determining a torsional moment within a rotor shaft, and modulating at least one of a wind turbine generator yaw orientation and a blade pitch orientation as a function of the determined torsional moment.
    Type: Grant
