Abstract
A method for braking a wind turbine including at least one rotor blade coupled to a rotor. The method includes selectively controlling an angle of pitch of the at least one rotor blade with respect to a wind direction based on a design parameter of a component of the wind turbine to facilitate reducing a force induced into the wind turbine component as a result of braking.
Claims18
A method for braking a wind turbine including at least one rotor blade coupled to a rotor, said method comprising:
- individually controlling an angle of pitch of the al least one rotor blade with respect to a wind direction based at least in part on a design parameter of a component of the wind turbine to facilitate reducing a force induced into the wind turbine component as a result of braking;
- and
- linearly varying a rate of change of the at least one rotor blade pitch angle.
A wind turbine system configured to couple to a power grid, said wind turbine comprising:
- a rotor comprising at least one rotor blade;
- a blade pitch actuator;
- and
- a processor coupled to said blade pitch actuator, said processor programmed to:
- individually control an angle of pitch of the at least one rotor blade with respect to a wind direction based at least in part on a design parameter of a component of the wind turbine to facilitate reducing a force induced into the wind turbine component as a result of braking;
- and
- linearly vary a rate of change of the at least one rotor blade pitch angle.
