Voltage Effects on Electric Power Systems Generators via Iterative Methods

Abstract

The determination or control of Voltages present at different points within the electric power system generators is very important for the smooth running of the power system operation. In this work, we examine the effect of high voltage on electric power generators with Y admittance bus matrix via iterative techniques, precisely Gauss- Seidel and Newton-Raphson method. Practical problems were solved for better understanding of the system. The results obtained shows that voltage had a great effect on the performance of the system as an increase in voltage increases the rate of convergence and make the slack bus to supply or generate more power than its limit capacity which may amount to breakdown of the system.
