A saturation model of induction machine by space vector

In this paper, a saturation model of an induction machine in terms of a space vector is presented. After the differences of stable and transient inductance of saturation are discussed, voltage equations by a space vector for the stator and rotor of an induction machine are derived which take account of the transient saturation of the main flux path. A torque expression by space vector in the same conditions is also discussed. Finally, a complete model of the induction machine by space vector is established. Some transient performances such as start-up of induction machine are simulated using this new model. The results of simulation show that the model presented in the paper is feasible
