Description
Summary:	This paper shows a Deadbeat controller for a wind generator during a balanced voltage sag condition. The control is made with a Stator Field Oriented Control technique using the DSOGI-QSG applied on the estimation of positive sequence of stator voltage vector and the stator current vector. The control strategy used is fully explained, and then it is tested using Matlab/Simulink, considering two scenarios: for the ﬁrst one, the generator must be forced to generate reactive power and maintain the active power in zero, during voltage sag condition according with the new network requirements. For the second test, the generator must maintain rotor currents within safe levels to prevent damages for the windings during voltage sag. Simulation results and conclusions about controller perfomance during the voltage sag condition are presented.
