Abstract (EN): In this paper it is presented an on-line dynamic hybrid transient stability formulation. This efficient and robust approach combines both a time domain integration method to compute the initial system trajectory with the extended equal area criteria to obtain the transient stability margins and the critical clearing times. The computer programs developed by the authors were applied to a multimachine power network. The results obtained with this hybrid formulation were compared with the solutions produced by a direct approch and by the Runge-Kutta method. Finally, some conclusions that provide a valuable contribution to the understanding of the multimachine power system preventive control are pointed out.
