Beschreibung
Zusammenfassung:	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.
