ABSTRACT:
A wind turbine36has a back-to-back AC/DC/AC power electronic converter chain in which the grid side converter48is connected in series with DFIG stator windings64.The machine side converter56is fed from the rotor windings54of the DFIG44.Series connection of the grid side converter48enables voltage sag ride-through capability via control of the stator flux.In the event of a grid voltage sag, the series converter allows for a controlled response in the stator flux and electromagnetic shaft torque, protects the machine side converter and enables continued power delivery to the grid.
