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 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 generator's output phase voltages; \n determining rotor rotation angle based on the measured generator's output phase voltages; \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; and \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.
