Vector Control Analysis of Doubly-Fed Induction Generator in Wind Farms

This paper presents vector control of grid-connected wind turbines; also the second goal of this research is to survey the vector control for wind turbines with doubly-fed induction generators (DFIGs) when a short circuit faults in grid happens. In fact in this paper, vector control of stator-flux is applied for stator- and rotor-side converters in order to control of active and reactive powers simultaneously, and to keep the DC-link voltage constant. Also the method performances are tested in different cases.
