Power Factor Improvement in Station No. 2 of the Al-Zawiya Oil and Gas Refinery

Abstract

This research addresses the importance of power quality and the problems affecting it, including induction motors that cause an increase in reactive power, resulting in a decrease in the electrical power factor and distortions in voltage and current waveforms, i.e., system instability. It aims to improve the power factor in order to minimize reactive power as much as possible at the generation side by using capacitors connected in parallel with induction motors to supply them with the reactive power they need, thereby reducing voltage drops in the network. A simulation model of substation No. 2 of the Al-Zawiya Refinery, which feeds the old refining unit, is designed using MATLAB software to raise the power factor value from 0.7–0.9 as much as possible using two methods of connecting capacitors: group connection and individual connection.
