“…However, most of them are connected directly to the electric power distribution system and they are exposed to unbalanced voltages. In theoretical point of view, the unbalanced voltages induce negative sequence current which produces a backward rotating field in addition to the forward rotating field produced by the positive sequence one [18]. The interaction of these fields produces pulsating electromagnetic torque and ripple in speed [19], [20].…”

This paper presents the application of MATLAB ® Simulink as a useful tool for predicting the performance of an induction motor. The influence of power quality problem on the performance of an induction motor is critically investigated. Mathematical modelling of an induction motor subjected to an unsymmetrical voltage conditions are presented. The results obtained from the simulation reveal the presence of rotor noise and vibration during operation of induction motor under voltage unbalance.

“…For U.S. industries, the cost associated with phase unbalance problems is up to $28 billion a year [11]. Industry typically employs several techniques for mitigating phase unbalances, including using switching to transfer loads among various circuits [12], properly selecting and configuring system components [13], and installing passive reactances that balance nominal load impedances [14]. Power electronic devices are particularly well-suited for correcting time-varying phase unbalances [15], [16].…”
