| titleOfInvention | Wind turbine having an expanded voltage range |
| abstract | The invention relates to a wind turbine having a wind rotor (12), a generator (14) powered therewith for generating electrical energy, and a connecting line for delivering the electrical energy, optionally via a system transformer (2). The wind turbine is provided with a voltage expander (3) that expands the voltage range of the wind turbine by means of an auxiliary voltage source. The voltage expander (3) comprises a small transformer (30) of its own having a primary and a secondary winding (31, 32), and a switching mechanism (33). The small transformer (30) is looped into the connecting line (17) with the secondary winding (32), and the switching mechanism (33) is connected to the primary winding (31) of the small transformer (30), actuating the primary winding (31) in a switchable multi-stage manner. Thus, a multi-stage expansion of the voltage range of the wind turbine is achieved, wherein thanks to the arrangement of the small transformer lengthwise in the connecting line, the small transformer needs to have only a fraction of the nominal power of the wind turbine. |
