The cascade methods of doubly-fed induction machine for generator system

This paper presents two solutions to cascade the doubly-fed induction machines in power generator systems. The first solution is a traditional one with control circuit located on stator-side. second new rotor-side. After analysis and evaluation, it shown that rotor side has advantages over Therefore, authors chose which study, analyze in-depth run simulation. results show proposed very good quality, output voltage of always follows grid-voltage even when changing gird-voltage or speed generator.
