摘要
Systems and methods for regulating voltage in a doubly fed induction generator (DFIG) system are provided. More particularly, the voltage of the auxiliary power feed in a DFIG wind turbine system can be regulated by outputting reactive power from a power converter to a reactive element coupled between the auxiliary power feed and a stator bus. The reactive element can include a winding of the transformer used to couple the wind turbine system to the electrical grid and/or an inductive element coupled between the output of the power converter and the stator bus. The voltage of the auXiliary power feed can be maintained within a reduced operating range while an increased operating range can be provided for wind turbine system.
