O USO DA ENGENHARIA DE AUTOMAÇÃO NA REDUÇÃO DO CONSUMO DE ENERGIA ELÉTRICA EM UM SISTEMA DE IRRIGAÇÃO POR PIVÔ CENTRAL

Abstract

This work describes the possibility of the use of Programmable Logic Controller (PLC) in set with Variable Drive Frequency (VDF), in systems of irrigation for central pivot, with the objective to increase the use of the efficiency of the electric energy, using nets Modbus-RTU, Zigbee and Compobus®, for communication between the equipment. The increase of the consumption of the electric energy in the agricultural way this directly associated with the technological development of agriculture is known that. Therefore the modern job techniques that optimize the rational use of the electric energy is basic in all the fields. The experiment was conducted on the campus of the Federal University of Lavras - UFLA within the Ph.D. program in Agricultural Engineering, resulting in a 19% reduction in power consumption of the system, having support of CNPq and FAPEMIG.
