Transient performance of a group of induction motors with terminal capacitors following supply disconnection

In this paper a model representing a group of three-phase induction motors, with terminal power-factor correcting capacitors, following disconnection of the group with its terminal capacitors as one unit from the supply, is derived. From this model the transient behavior of the motors of the group and the interaction between them, following supply disconnection is investigated and the effect of the terminal capacitors on the transient behavior of each motor of the group, regarding terminal voltage, stator currents, airgap powers, is shown.
