Beschreibung
Zusammenfassung:	A wind turbine comprises a permanent magnet synchronous generator, a main converter, a main converter controller, a wind turbine master controller and an electrical power supply stage comprising an electrical energy storing device. A startup of the wind turbine can be performed using electrical energy from the electrical energy storing device independent from a power supplying grid and/or a combustion engine. After startup, the wind turbine can be operated in an island mode by controlling an intermediate voltage of the main converter by the main converter controller and retrieving power from the synchronous generator independent from the electrical energy storing device.
