Sistema de monitoramento de variações de tensão de curta duração em redes de distribuição de energia

Abstract

The high level of automation in the modern electric equipment, with an increase in the complexity of the functions that electric charges perform in the control of processes, made them more sensitive to fluctuations in the supply voltage. This type of problem can have consequences ranging from simple failures in home appliances to the complete interruption of a production line, causing a significant economic impact. Among the most common types of voltage fluctuations are the Short-Duration Voltage Variations, defined by its magnitude (interruption, sag or swell) and duration (momentary or temporary). Thus, the objective of this paper is the development of a robust, low-cost system, that performs the detection of the Short-Duration Voltage Variations. In addition, all the information about the voltage variation events is going to be saved and released online for consultation by the energy providers and clients.
