Power quality impact on performance and associated costs of three-phase induction motors

This paper aims to present investigation results related to induction motors operation under nonideal supply conditions. The motors are of squirrel cage type and the nonideal conditions are associated to harmonics, unbalances, voltage sag and swell, etc. The studies are carried out using time domain modeling and the SABER simulator. Using this approach, computational results are derived in order to compare the nonideal motor performance to the ideal ones so that the real supply condition effect upon the motor behavior can be highlighted. In addition to technical aspects, the power quality impact on energy and financial waste and is also considered.
