| dc.description.abstract | Voltage sag is one of the primary concerns in power quality disturbance, even though there are several ways to characterize voltage sag, two basic characteristics i.e. sag magnitude and sag duration are the two most commonly used. Electromagnetic torque generated by an induction motor is directly proportional to the square of the voltage. Due to the wide use and popularity of induction motors, this thesis investigates the effect of voltage sag duration, loading conditions, and power rating on the performance of induction motors under different voltage sags at various points of sag initiation. In the MATLAB Simulink environment, simulations of two different rated induction motors under various voltage types of sags of magnitudes (0.2 pu,0.5 pu, and 0.8 pu) and duration 10 cycles (instantaneous sag) or sag of duration 1 sec (momentary sag) are performed. Results of the simulations have been compared based on torque peaks and current peaks. It has been found that the torque peak for an instantaneous sag is similar to the torque peak for a momentary sag for each type of voltage sags. Whereas current peaks were affected by the sag duration it has been found for momentary voltage sag of Type A, Type C, and Type D the magnitude of the current peak increases in comparison to instantaneous voltage sag. The effects of loading conditions and power rating are also investigated. | en_US |
