Abstract
Concerns for wind energy as alternative energy have been highly increased. In this paper, the mechanism between mechanical wind turbine and power generating system is presented to specify the relationship of the energy transfer. Grid-connected DFIG could achieve unity leading power factor, in addition to variable speed operation at the wide sub-synchronous and super-synchronous shaft speed range and also its independent control of torque and reactive power is possible.
