Métodos geradores de eficiência energética: um estudo de caso na companhia de água e esgoto do Ceará

Abstract

Everything related to energy efficiency and renewable energies has been increasingly addressed and disseminated within the various aspects of electrical engineering and related areas of technology as a whole. Moreover, this is due to the climatic adversities worldwide in recent years, which has led to a decrease in the volumes of reservoirs, among other environmental complications. Another key factor to leverage issues has been the population growth and technological advances are again a great demand for energy, making of the electric sector return to a better energy use in residential, commercial and industrial scale. The objective of this study is to carry out the energy efficiency analysis combining the theoretical, technical and economic points of view to generate measures to reduce energy waste. A huge number of practices are now available in the market with such purposes, and here the power factor correction, the implementation of high-efficiency motors, the adjustment of lighting and the possible installation of a photovoltaic system were here observed in an in-depth way. For that, a case study, on the CAGECE Company, where was applied, analyzing the energy history of the consumer units, surveying the installed load, analyzing the motors installed in the units. The feasibility of all the aforementioned applications in which it was verified, as well, in the case of the photovoltaic system, due mainly to the excellent geographic location for this purpose, however, and they can be used separately or even together, although they presented economic and miscellaneous paybacks.
