Abstract :
This paper presents the results obtained from a PSCAD/EMTDC dynamic fault simulation of a grid connected Doubly-fed Induction Generator (DFIG). The transient stability performance of the DFIG is investigated; case studies which demonstrate the possibility of wind turbine generator torsional vibration, and the concept of Critical Clearing Time (CCT) for the DFIG are presented and the results are compared to those of a Fixed Speed Induction Generator (FSIG).
