Abstract (EN): In this paper it is simulated the effect of the circuit breakers reclosure in the transient stability of an electric power system using a new hybrid approach. This efficient and robust formulation combines both a time domain integration scheme to compute the initial system trajectory with the equal area criterion to obtain the transient stability margins and the critical clearing times, In this hybrid approach it is used a stop criterion to provide automatic and early termination of the simulations as soon as post-fault (un)stability are detected. The early termination algorithm assess the transient stability of the multimachine power network based on the concept of the dot products from the potential energy boundary surface method. The computer programs developed by the authors were applied to a multimachine test power network. The results obtained with this new 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 auto-reclosing effect in the transient stability problem are pointed out.
