State the advantages of Double Fed Induction Generator

Answer»

efits of supplying the rotor circuit of a DOUBLY Fed Induction Generator (DFIG) by the Modular Multilevel Matrix Converter (M3C) are presented. The M3C allows higher rotor voltages, lower rotor currents and a higher REDUNDANCY compared to existing SOLUTIONS. Filters are dispensable due to the generated multilevel voltages. In CASE of a line voltage drop the M3C arm voltages can be used to generate temporarily higher rotor voltages which may help to control the rotor currents during faults. subconverter 1
