Estudo de eficiência energética no sistema de força motriz em indústrias de transformação de subprodutos do abate de animais

Abstract

This work presents the development of a standard diagnostic model for the evaluation of energy potential in the powertrain system in an animal slaughter by-product processing industry, which seeks a standard model for the other units of the company in question. With this aim, an energy efficiency study was carried out with the replacement of motors and the application of efficient drives of these and, at the same time, the quality of electric energy in the company was evaluated to find the best model according to the characteristics of the industry. In this way, we analyzed energy consumption through energy tariffs, energy quality with electrical quantity measurements of the engine control center (CCM) and two main electric motors, selected from their relevance and their highs consumption. The measurement in these two engines, besides being able to serve as an indicator of quality, was also used to evaluate the replacement of the start of these equipment’s, thus promoting energy efficiency. Based on the applied methodology, the demand contract was verified, which should be increased by 3.57% if no efficiency measures were taken. Finally, to validate the applicability of the model, it was estimated the reduction with the replacement of compensating keys by frequency inverters.
