One of the variable speed wind turbines most commonly used today is the doubly feed induction generator(DFIG). A control scheme of DFIG is discussed in this paper. The power converter connected to the grid side (bus) is modeled and controlled using voltage vectororiented dq reference frame, whichguarantees that the active power can be controlled by the daxiscurrent component and consequently the DC bus voltage. The qaxis component is forced to be zero in order to ensurethe unitary power factor. Astator flux oriented control in the rotor circuit converter is used.A novel GDSC-PLL method is used in order to achieve an efficient synchronization with the grid.Onthe order hand, this paper presents an analysis about the DFIG (Double Feed Induction Generator) behavior during voltages sags

Palabras clave : doubly fed Induction generators; control system.
