Dispositivo microcontrolado para medição de qualidade da energia elétrica

Abstract

This present work consists at the implementation, test and viability analysis of a micro-controlled device able to measure power quality, obtaining the measurement of: RMS values of voltage and current; real, reactive and apparent power; power factor based the fundamental frequency; proportional total harmonic distortion over the phase voltage at the electric network. The implemented prototype at this project aims to present a low-cost configuration, integrating the acquisition, processing and communication functionalities into the ARM Cortex-M3 microcontroller so that cost optimization and easiest implementation at the electric energy distribution network. After a theoretical analysis over the base concepts for the Project implementation, the objectives and motivation just like the detailing and methodology of the present items of this project. Under its development, the described and implementation over the hardware and software sections at this project so then a test sequence realization, aiming the developed prototype's efficiency over this project. Through the tests result analysis a conclusion is made based on the national standard specification.
