Abstract :
With increasing penetration of wind turbines in the utility grid new regulation codes have been issued that require them to have low voltage ride-through capability. In this paper, a passive resistive network, consisting of shunt and series elements are applied at the stator side of DFIG wind turbine is presented. The network is inactive during steady state operation and enabled for short intervals of time during the initiation of voltage sag and recovery events. Computer simulation and experimental results confirming the operation during balanced and unbalanced voltage sags are shown in the paper.
