Abstract
A wind turbine generator controller is described. The controller comprises switching circuitry, for selectively activating and deactivating one or more transducer circuits, and overcurrent detection circuitry, for detecting an overcurrent state in relation to one or more of the transducer circuits. The switching circuitry is responsive to the detection on an overcurrent state to selectively deactivate one or more of the transducer circuits.
Claims16
A wind turbine generator controller, the controller comprising:
- switching circuitry, for selectively activating and deactivating one or more transducer circuits;
- and
- overcurrent detection circuitry, for detecting an overcurrent state in relation to one or more of the transducer circuits;
- wherein
- the switching circuitry is responsive to the detection on an overcurrent state to selectively deactivate one or more of the transducer circuits.
(canceled)
A method of controlling transducers in a wind turbine generator control system, the method comprising:
- detecting an overcurrent state in relation to one or more transducer circuits;
- and
- responsive to the detection on the overcurrent state, selectively deactivating one or more of the transducer circuits.
(canceled)
A wind turbine comprising:
- a tower;
- a nacelle disposed on the tower;
- a rotor extending from the nacelle;
- a plurality of blades coupled to a distal end of the rotor;
- a wind turbine generator controller, comprising:
- switching circuitry, for selectively activating and deactivating one or more transducer circuits;
- and
- overcurrent detection circuitry, for detecting an overcurrent state in relation to one or more of the transducer circuits;
- wherein the switching circuitry is responsive to the detection on an overcurrent state to selectively deactivate one or more of the transducer circuits.
