A QUANTITIES METHOD OF INDUCTION MOTOR UNDER UNBALANCED VOLTAGE CONDITIONS
Abstract: The most complete
definition for the voltage unbalance is using complex voltage unbalance factor
(CVUF) that consists of its magnitude and angle. Unfortunately, the definition
did not distinguish between undervoltage and overvoltage unbalance conditions.
In this paper, the analysis of the motor is performed using the method of
symmetrical component and MATLAB software is used to investigate the
performance of induction motor. The simulation results show that the
International Electrotechnical Commission (IEC) definition of the voltage
unbalance can be applied to evaluate total copper losses precisely. However,
the phase angle of unbalance factor must be included for accurate predicting of
peak currents and peak copper losses of the phase windings of the motor.The
unbalanced conditions which distinguish between under and over voltage
unbalance must also be taken into consideration for assessing all the
quatities.
