Evaluation of the Effects of the Regular Voltage Fluctuations on Induction Motors Behavior

Flicker is an important power quality index and is currently receiving increasing concern from power system engineers. The voltage fluctuations of the electrical power supply can generate many undesirable effects on both industrial and domestic apparatus. This paper presents the methodology and results of investigations undertaken to examine the response of an induction motor to small perturbations in the supply voltage. The aim of this paper is to evaluate the effects of the low-frequency voltage amplitude modulation on induction motors behavior. The work is based on small-signal model of induction motor to describe induction machine behavior. Furthermore the induction motor response to frequency of voltage fluctuations is examined. It will be shown that different induction motors have various behaviors with respect to regular voltage fluctuations.
