Application of SMES Unit to Enhance the Dynamic Performance of DFIG during Misfire and Fire-Through Faults

M.Baby, R.Pari

The modern wind turbines are based on doubly fed induction generators (DFIG) with a rotor side converter (RSC) and grid side converter (GSC) connecting the rotor winding to the grid. Misfire and fire-through are the commonly occurred faults in the rotor side converter (RSC) and grid side converter (GSC). The superconducting magnetic energy storage (SMES) unit is used to supply power to the system during Misfire and fire-through faults in order to maintain its dynamic performance. Simulation results without and with SMES connected to the system are presented, compared, and analyzed
