Analysis and simulation of a 1.5 MVA doubly fed wind-power in MATLAB SimPowerSystems using crowbar during power systems disturbances

The performance of a 1.5 MVA wind-power doubly fed induction generator (DFIG) under network fault is studied using simulator developed in MATLAB-Simulink. The simulator consists of the DFIG analytical model, the detailed frequency converter model including passive crowbar protection, and model of the transformer. Simulation results show the transient behavior of the doubly fed induction generator when a sudden voltage dip is introduced with and without the crowbar implemented.
