Projeto para a correção de reativos do Centro de Eventos do Ceará utilizando controladores automáticos de fator de potência

Abstract

Electric energy is part of today’s society, being used from small domestic appliance to large machines in industries. From the increasingly abrupt growth of cities and appliance that run on electricity, several studies are carried out with the purpose of predicting the need for new electric power generators, however, in the same way that new power stations must be installed, it is also essential to use electricity as efficiently as possible. For the efficient use of electricity there is one among many variables that measures the energy being transformed into work and the amount being consumed in total, this is called the power factor. Therefore, this work aims to make an electrical project for the Ceará State Events Center for the application of automated capacitor banks for the effective power factor correction. Lastly, the result shows that the installation of automated capacitor banks through power factor controllers,with total reactive power of 1760kVAr divided into two types of stages (45kVAr and 25kVAr) to cover all the needs of each transformer, presents a much greater financial advantage for the Government, stopping to pay fines for low power factor, electricity bills suffer a considerable reduction in their gross value with an average of R$ 261.882,03 per year, and within one year the material costs of the capacitor bank of R$ 252.299,86 the equipment recover its market value.
