Good Agreement

The effects of magnetic saturation on the operation of induction motors driven by static converters are analyzed. A mathematical model based on magnetic harmonic functions is used to account for saturation. Distortions on the air gap flux due to non-linear magnetic characteristics lead to appearance of space harmonics in the resultant flux density distribution. This causes specific distortions in stator and rotor time quantities, which are different from those due to static converter. Operation with six pulse and sinusoidal PWM converters under saturated conditions is considered. Comparisons of experimental and simulated results are presented and found to be in very good agreement.

This paper deals with two methods of including magnetic saturation in induction machines d–q equations. The first one, based on the main flux saturation, is characterized by the well-known phenomenon called cross-saturation. The second avoids such phenomenon consisting of magnetic coupling between orthogonal axes d and q. It was proven that, if the nonlinear static and dynamic machine inductances are suitably modeled, both methods give exactly the same results whatever the mode of operation motor or generator. As unusual, comparison between models shows that the second method without d–q cross-coupling is the advantageous and thus advised.
