Estudo de qualidade de energia elétrica nas subestações do Instituto de Computação(ICOMP) e Faculdade de Tecnologia(FT) da Universidade Federal do Amazonas

Abstract

Electrical power quality is an essential concern for various sectors of industry and society, as electrical phenomena resulting from poor power quality can result in large economic losses and significant damage to electrical equipment and systems. Ensuring the quality of the energy supplied is essential for the proper functioning of industrial equipment, systems and processes. In this context, this study proposes to analyze the quality of energy delivered by the substations of the Institute of Computing and the Faculty of Technology, based on Prodist Module 8 and the IEEE Standard for Harmonic Control in Electric Power Systems. The proposed study evaluated charging levels, harmonics, power factor and steady-state voltage over three days, being able to detect anomalies such as short and long-term overloads, precarious and critical voltage levels, and current harmonic variations. above specifications. In addition, energy consumption characteristics were analyzed, allowing more effective monitoring of electrical quality. The work began with the installation of analyzers at selected substations to meet measurement requirements and the generation of the database. Then, the data was processed using Python to prepare reports with diagnoses of the measured energy quality. The work is organized into four chapters, which cover everything from theoretical concepts about substations and energy quality to the analysis of results and conclusions.
