Estudo de caso: proposta de melhoria técnica e econômica por correção do fator de potência em uma indústria alimentícia.

Abstract

The power factor is an index that measures the efficiency in the use of electrical energy. When the power supply to an inductive load is activated, a phase shift phenomenon occurs between the voltage and current waves, causing the emergence of Reactive Power. This lag is calculated by the Power Factor (PF). One of the ways to improve energy efficiency in an industry sector is by reducing the surplus of reactive energy, thus causing several improvements for it. The objective of this work is to carry out a case study of the financial and technical benefits of installing a new Capacitor Bank to replace the old one that no longer works for years. For the development of the study, a factory in the food sector was chosen, where it is necessary to correct the power factor, thus reducing the fine received for exceeding the minimum allowed power factor. For this, technical data were collected referring to the current, voltage, power and power factor used for dimensioning the capacitor bank that is carried out in this study.
