Análise da qualidade de energia no sistema elétrico da Universidade Tecnológica Federal do Paraná - Câmpus Pato Branco

Abstract

This analysis presents a theoretical-conceptual approach to evaluate the electric power quality of the electrical system of the Federal Technological University of Paraná - Pato Branco Camp. The analysis consists of monitoring the electrical system using a Fluke brand of energy quality analyzer and classifying the disturbances found by means of the Electric Power Distribution Procedures in the National Electric System, made available by the National Electric Energy Agency. Also, use some International Electrotechnical Commission standards to complement the work. The methodology used presents MATLAB and Power Log software for graphical and statistical analyzes and demonstrates the use of a field survey in which, through a questionnaire application, the electrical system was found by the consumer's vision. It presents a planning to carry out as measurements, based on field research and information acquired from the electrical system. It discusses the results based on the pertinent literature, our datasets acquired and the indicators of energy quality, resulting in a current situation of the energy quality of the analyzed electrical system, where it encounters some problems such as: voltage sags, voltage unbalances, current unbalances and voltage fluctuation.
