A resonance damping system for a wind turbine having a generator connected to a power grid, the resonance damping system comprising:
- an adaptive resonance damper, operable to provide a control signal for the generator, wherein the variable torque signal of the adaptive resonance damper is automatically adjusted according to a parameter which represents a grid condition.
A vibration damping method for a wind turbine with a turbine rotor mounted on a tower and coupled to a generator by a drive train, the wind turbine being connected to a power grid, the vibration damping method comprising:
- determining a generator demand torque based on sensed rotational speed of the generator;
- modulating, by an adaptive resonance damper, the generator demand torque by providing a variable torque signal;
- detecting a grid condition represented by at least one parameter;
- and
- adjusting the variable torque signal of the adaptive resonance damper automatically according to a grid condition represented by at least one grid parameter.
A wind turbine having a generator connected to a power grid, with an adaptive resonance damping system, the resonance damping system comprising:
- an adaptive resonance damper, operable to provide a variable torque signal to control the torque produced by the generator, wherein the variable torque signal of the adaptive resonance damper is automatically adjusted according to a grid condition represented by at least one grid parameter.
