New methodology for the prediction of motor starting udeffect on bus voltages of interconnected power systems

摘要

A new methodology is proposed in this paper capable of predicting the impact of induction motor load starting on the bus voltages of an interconnected power system. The profile of the voltage sag is predicted for each bus, which is used to improve the power quality of a system. The methodology is investigated with the use of a four bus, as well as fourteen bus IEEE interconnected system. Mathematical and simulation results demonstrate the effectiveness and applicability of the proposed methodology for the application.
