RESUMO
The spread and the interconection of Electrical Power Systems have been stressed the employment of dynamic equivalents by Electrical Power Companies for representing system áreas that they are not responsible for at planning and operation studies. Due to system model dimension reduction, studies have become faster with reduced costs and computational task requiriments. Besides, dynamic equivalents overcome computational system limited memory capability problems ant fit easily into the up-to-date phisical and coceptual structure of the minicomputers. As an aid to Electrical Power System Stability studies, the objective of the dynamic equivalents is to simulate external system. The great merit of this lind of overcoming is its ability on revealing the system dynamic trend. This research shows a method of computing dynamic equivalents for transitory stability studies based con the agregation of the generators that oscilate together from an initial perturbation on. The reduced model, got from topological transformations, is built of parameters that are similar to usually employed on Electrical Energy System modeling been numerically stable. At the end, some results are shown as an attempt to test the performance of the method.
