Abstract:
A method and a system for adjusting a wind-turbine power take-off are provided. The system comprises: a rotor position sensor operatively connected to a synchronous generator, a plurality of phase current sensors, an active rectifier, and a micro-controller. Instructions stored on the micro-controller, when executed, are configured to cause the micro-controller to execute the method comprising: obtaining a measurement of a rotor rotation angle; determining an actual rotation speed of a rotor of the synchronous electric generator; and executing an optimization algorithm to determine an optimized speed of the synchronous electric generator. The synchronous electric generator is controlled based on the determined optimized speed by at least one of: setting an electromagnetic torque on a shaft of the synchronous electric generator, setting currents in windings of the synchronous electric generator, and controlling the active rectifier boost converter function operating in conjunction with a down converter.

Claim (Index 9):
A system for adjusting wind turbine power take-off, the wind turbine being operatively coupled to a synchronous electric generator, the system comprising:\n a rotor position sensor operatively connected to the synchronous electric generator, the rotor position sensor being configured to determine a rotor rotation angle; a plurality of phase current sensors operatively connected to the synchronous electric generator, the phase current sensors being configured to determine phase currents at the output of the synchronous electric generator; an active rectifier being configured to generate an electromagnetic torque by forming sinusoidal in-phase currents in the phase windings of the synchronous electric generator; a microprocessor, operatively connected to the synchronous electric generator, the active rectifier and a down converter being configured to control operation of at least one of the synchronous electric generator, the active rectifier and the down converter, based on the rotor rotation angle and the phase currents.
