This paper addresses the dynamic modelling of large (MW) capacity Doubly Fed Induction Generators (DFIG) wind turbines using Pscad/Emtdc™ and Matlab/Simulink™. Suitable speed and reactive power controllers are implemented and described. Application studies are conducted to observe the performance of the DFIG during power system disturbances such as three-phase faults developing in different points of the network. These studies are used to determine the DFIG's fault current contribution and power converter rating required for fault ride-through capability and protection requirements. Simulations results are presented and discussed using typical turbine and network data for wind farm facilities.
