Power Factor Compensation on Distorted Low Voltage Power Systems

V.Bhanu, Shaik Rafi Kiran

Harmonic resonance has become a major hurdle for performing power factor compensation in commercial power systems, due to the proliferation of harmonic producing-loads. This paper presents an intelligent controller for power factor compensation that can perform power factor correction under varying demand conditions without exciting harmonic resonance. Practical and robust control algorithms are proposed using micro-controller. The controller relies on common low cost sensing devices and hence can be constructed as a retrofitting device to replace existing power factor correction controllers.
