Title: POWER FACTOR DETERMINATION OF INDUCTION MOTOR FREQUENCY CONTROLLED DRIVES
Keywords: power factor measurement, induction motor, vector control, scalar control, IR-compensation.

Abstract: Some methods for determining the power factor in frequency controlled induction motor drives are analyzed. A novel approach is proposed for power factor determination only by measuring the stator currents and by using support frequency, equal to the frequency of the stator voltage without measuring this voltage. The approach is simple and can be described in an elegant mathematical way. The effectiveness of the approach is confirmed by software simulation experiments.
