ANÁLISE DA QUALIDADE DE ENERGIA ATRAVÉS DE UM ESTUDO DE CASO

Abstract

Electricity is considered a commercial product, and like any commercial product, its quality is demanded by consumers, mainly the consumers of higher powers, who are responsible for a considerable part of the consumption of electric energy. The sensitivity of some equipment used in certain sectors of the electroelectronics test the quality of the energy, these equipments are sensitive to variations in the parameters that define the quality of electric energy, it is necessary that the electric energy is continuous, free of variations and disturbances. The energy is distributed and marketed by concessionaires, who to supply energy with quality, are regulated by a national body, in Brazil, this body is denominated as National Agency of Electric Energy (ANEEL). ANEEL establishes the necessary procedures for the concessionaires to commercialize electric energy. This work was developed to evaluate the consumption of electric energy of a coffee trading company, in relation to consumption measured by the concessionaire. According to the company, the value measured by the concessionaire is excessive in relation to the installed electric plant. This monograph was prepared based on bibliographic studies, based on the procedures required by the regulatory agency in effect, and presenting, through a case study, the results of an energy quality analysis at the company's General Distribution Point (Q.D.G.). In order to carry out an assessment of possible improve
