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 qua...

The major purpose of this work is to design the controllers for controlling variable speed, pitch wind turbine (WT) with doubly fed induction generator (DFIG). Vector control strategy adopted DFIG active and reactive power. Generator torque provide regulated real power minimum fluctuation. fixed gain proportional-integral (PI) controller designed converter rotor side grid has limited operating ...

Voltage dips are brief but frequent disturbances that can be defined as the most important problem affecting all electrical grids, it cannot completely avoided and represent main priority for industry. This study remains part of monitoring quality energy’s field. Its aim is to apply two approaches signals improving failure recognition in wind turbine conversion chain. One based on combination s...
