Abstract:
A method and a system for adjusting a wind-turbine power take-off. The system comprises: a plurality of phase current sensors and a plurality of voltage sensors operatively connected to a synchronous electric generator, 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 generator's output phase voltages; determining rotor rotation angle based on the measured generator's output phase voltages; executing an optimization algorithm to determine an optimized speed of the synchronous electric generator based on a target energy value. 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 10):
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 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; a plurality of voltage sensors operatively connected to the synchronous electric generator and configured to determine phase voltages at the output of the 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; and 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 phase currents and the rotor rotation angle determined from the phase voltages.
