Science and Education Publishing American Journal of Electrical and Electronic Engineering 2328-7357 4 5 2016 11 30 New Methodology for the Prediction of Motor Starting Effect on Bus Voltages of Interconnected Power Systems 139 147 EN Alexis Polycarpou Hassan Nouri Power Systems, Electronics and Control Research Laboratory, UWE Bristol BS16 1QY, UK Ali Azizpour AJEEE2016453 10.12691/ajeee-4-5-3 2016 8 30 2016 10 6 2016 11 28 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.
