This study presents the quantitative transient stability assessment and comparison for conventional synchronous generator (SG) and wind turbine generators (WTGs) by studying the impact of the fault clearing time the grid coupling the inertia constant the generator terminal voltage sag and the slip on fault responses. The assessment and comparison is performed by evaluating the transient stability index through the modified transient energy function. Simulation results show WTGs exhibit different transient responses on the occurrence of faults as compared with conventional SG. This justifies the necessity of study in greater depth for reliable operation of conventional power systems with the integration of large wind power.
