Induction motor equivalent circuit for dynamic simulation

Abstract

until now the use of equivalent circuit for induction motor has been limited for steady state analysis. The equivalent circuits for dynamic simulation proposed until now, are not able to obtain the transient response of the induction motor, because they lack of mechanical component representations. Complex non-linear matrices are used instead. Here electrical analogy of mechanical system is integrated with d-q equivalent circuit derivates from the stator frame of reference to create a complete equivalent circuit for three-phase induction motor which is suitable for dynamic simulation. Finally this paper presents results that validate the proposed circuit by comparing it with that obtained with mathematical models.
