Abstract (EN): In this paper it is used a hybrid approach to study and analyse the tripping effect of one or more generators in the transient stability of a multimachine power system. This efficient and robust approach combines the advantages of the time domain integration schemes to compute the initial system trajectory with the equal area criterion. The transient stability assessment is obtained using stability indices. Consequently, the time domain simulation is only computed during a short integration period. This early termination procedure reduces drastically the computing time. The software package TRANsySTEM developed by the authors was applied to a multimachine test power network. The results obtained with this hybrid formulation were compared with the solutions produced by a time domain simulation program. Finally, some conclusions that provide a valuable contribution to the understanding of the generators tripping effect in the transient stability problem are pointed out.
