Proposal of a power factor correction methodology in a nonlinear load scenario

This paper describes some strategies for power factor correction, which consist in the use of capacitor banks and/or tuned passive filters. The methodology is based on the power factor concept in the presence of harmonics, which takes into account the displacement factor and pollution factor. Curves can then be plotted in order to distinguish three regions, which are associated to power factor correction. Three hypothetical cases are properly evaluated in ATPDraw (Alternative Transients Program) environment, where power factor correction is performed at the low voltage side. The strategy has proven to be effective for all proposed cases, being a useful tool in an effective, safe, and economically viable approach.
