The invention relates to a wind turbine comprising a wind rotor (13) for driving a generator (14) comprising a converter (15) for generating electric power, a controller (2) and an internal power supply unit (4), for which an auxiliaries transformer (3) is provided which is connected at the feed-in connection (31) thereof to the generator (14) and/or converter (15) via a power link (17) and supplies power to the internal power supply unit (4) via the low-voltage connection (41) thereof. A switching device (6) for the auxiliaries transformer (3) is provided which is designed to reverse a power flow through the auxiliaries transformer (3) in a reverse operating mode. For this, in the reverse operating mode the feed-in connection (31) of the auxiliaries transformer (3) is switched as output and is connected to a high-voltage consumer, and an output connection (32) of the auxiliaries transformer (3) is switched as input and is fed from the low-voltage connection (41) of the internal power supply unit (4). Therefore, by virtue of the power flow through the auxiliaries transformer being switched over to a reverse operating mode, said auxiliaries transformer can be used to generate the high-voltage level required on first operation, for which is was previously necessary for a separate booster transformer to be provided. |
