Improving the Power Factor at Unbalanced Consumers

Abstract

Unbalanced consumers have led to power quality problems. It is therefore necessary to have on hand solutions and equipment capable of improving the power quality. This paper provides a comparison on improving the power factor at unbalanced consumers by using two methods the installation of a capacitor in the PCC (point of common coupling) – analysis made through analytical method; and installation of a shunt active power filter in the PCC – analysis made through simulation using Matlab/Simulink software.
