Sistema de controle de demanda energética para indústria

Abstract

Since its invention, electrical energy has become indispensable in people’s life, domestic use – with the comfort generated by electricity – to the crucial role in production industrial process. Due to the environmental impact triggered by the generation of energy, it is important that it be used consciously. Furthermore, since the installed infrastructure is based on a specific demand, the energy consumption established between hiring and power distribution energy is an important topic to be appreciated, mainly in the industrial branch, where the factories are in constant expansion, due to the increase capacity of production. The demand control project proposed in this work aims to automate grain dryer fan motors, which they can be turned off according to the company's demand. For this system, a motor control logic was proposed to protect the transformer, optimize the drying logic and, mainly, control the energy demand obtained from distribution. For this, controllers, a market supervisory system and Modbus communication protocol were used. The results showed that the application of the automation system can generate considerable cost reduction for the company.
