Qualidade da distribuição de energia elétrica no Brasil.

Abstract

This paper aims to evaluate the performance of national electric supply companies regarding the quality of the product and services provided. The evaluation initiates presenting a typical power distribution system and describing the main disturbances that affect the quality of the electricity distributed. Regarding the current regulation’s standards, it describes the terminologies, the phenomena, the parameters and the reference values concerning disturbances of the voltage waveform, as well as it presents the continuity indicators, provided by ANEEL at PRODIST, whereby it is possible to measure the services’ quality. In sequence, it details some regulatory incentives adopted to increase electricity supply quality, and the impacts of these actions at the tariff arrangements. Lastly, it presents a comparison based on the electric supply companies about the voltages levels conformity indicators, continuity indicators and average service time to emergencies situations indicators.
