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 1):
A method of adjusting a wind-turbine power take-off, the method executable in a system including:\n a wind turbine; a synchronous electric generator operatively coupled to the wind turbine; an active rectifier and a down converter for controlling voltage and current settings of the synchronous electric generator; and a micro-controller configured to control operation of at least one of the synchronous electric generator, the active rectifier and the down converter, the micro-controller storing computer executable instructions, which instructions when executed are configured to cause the micro-controller to execute the method comprising:\n obtaining a measurement of a rotor rotation angle of the synchronous electric generator; \n based on the measurement, determining an actual rotation speed of a rotor of the synchronous electric generator; \n receiving a target energy value including one of a target consumer voltage and a target consumer current; \n executing an optimization algorithm to determine an optimized speed of the synchronous electric generator based on the target energy value; \n controlling the synchronous electric generator based on the optimized speed of the synchronous electric generator, the controlling being executed by at least one of:\n setting an electromagnetic torque T E  on a shaft of the synchronous electric generator, proportional to a linear value of a current value of the synchronous electric generator, determined by the phase currents i A , i B , i C  generated by the active rectifier; \n setting currents i A , i B , i C  in windings of the synchronous electric generator, the currents being in a sinusoidal form; and \n controlling the active rectifier boost converter function operating in conjunction with the down converter.
