Estudo de caso da correção de fator de potência industrial

Abstract

Increasing the consumption of electric energy requires a more efficient use of it. In this context, the aim of this paper is to study two cases of power factor correction in the industrial sector, once this leads to a decreasing demand for reactive energy supplied by the generating units and releases its capacity to supply active power. Two methods will be discussed and exemplified for power factor correction, one of them when the industry is in the design phase and the other one is operating. Through these methods, the capacitor banks were designed and their economic feasibility was evaluated by obtaining a return of capital in 2 years for the first case and 7 months for the second one.
