Abstract
A wind turbinehas a back-to-back AC/DC/AC power electronic converter chain in which the grid side converteris connected in series with DFIG stator windings The machine side converteris fed from the rotor windingsof the DFIG Series connection of the grid side converterenables 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.
