Three-phase asynchronous motors represent between 60% and 75% of world consumption. Their high incidence in the load curves of a country and, consequently, in the operation of electrical systems makes necessary the development of models that allow their analysis in an effective way and their use in software for the analysis of electrical networks. In any industry there are a large number of electrical machines located in Motor Control Centers all connected to the same busbar. It is possible to group all the motors that are connected to the same busbar forming a single equivalent motor. This paper presents a methodology for obtaining the parameters of an aggregate. From its application to three different case studies, the parameters of a universal aggregate model of a three-phase asynchronous motor for power system analysis are obtained.

Palabras clave : aggregate of electric motors; electrical power systems curve; three-phase asynchronous motor model.
