Zusammenfassung: | A wind turbine and operating method include a double-fed induction generator with a generator rotor and a generator stator, a power conversion assembly having respective rotor-side and line-side power converters, and a load. The generator rotor is coupled to the rotor-side power converter. The line-side power converter and the load are coupled to a grid via a low voltage winding of a transformer. A first sum of a rated current of the generator rotor and a rated current of the load is more than an upper current limit of the low voltage winding. When operating the generator at a sub-synchronous speed, a first current is provided to the generator rotor that is less than a normal generator rotor current, and a second current is provide to the load, wherein a second sum of the first current and the second current is equal to or less than the upper current limit of the low voltage winding. |
