Harmonic Emission of Non-Linear Loads in Distribution Systems - A Computer Laboratory Case Study

Abstract

In this research a typical university computer laboratory was simulated, using experimental results obtained from actual non-linear loads tested, to determine the extent of the current and voltage harmonics produced by the simulated laboratory in a best (least harmonics) and worst (most harmonics) case when compared to IEEE standards on harmonics. A way to mitigate the harmonics through passive filtration techniques was proposed. The benefit of applying power factor correction was also considered.
