PROPOSTA DE OTIMIZAÇÃO PARA ACIONAMENTO FLEXIBILIZANDO TÉCNICAS DE CONTROLE E ECONOMIA ENERGÉTICA

Abstract

This work presents the study of a project implemented and in operation, on the drive for three - phase induction motor (MIT) used in two asynchronous motors with power of 125cv installed in a subsystem of hot air generation in the Kerry do Brasil food industry . It intends to update the same system by implementing techniques acquired in the Electrical Engineering course to start the motors through a frequency inverter which uses the method of frequency control and voltage supply using the technology of power electronics to replace the current model, a compensating switch that uses autotransformers to lower the electrical voltage in the static circuit minimizing the starting peak of the motors. The present study seeks to know the three-phase induction motor, to develop automation using ladder programming logic for speed control and improvement of the industrial process, contributing to minimize costs with electric energy and thermal energy from the burning of BPF 1A fuel oil, and thus also reflecting on the control of environmental impacts arising from industrial operations. The present work aims to evaluate and propose changes in the current drive with great expectation of energy saving. Through research and data collection, the improvement needs were presented, thus suggesting possible solutions through the automation system to be implemented.
