Abstract

A system and method for supplying increased frequency supporting current from a doubly fed induction generator (DFIG) to assist in maintaining grid stability is provided. The output capability of a line side converter associated with the DFIG is enhanced by significantly increasing the current handling capacity of electric switches forming the converter. A dynamic brake is also provided across a DC link bus coupling the line side converter to another converter coupled to the rotor of the DFIG. The dynamic brake is controlled based on the voltage across the DC link bus.
