Monitoramento de interrupções de fornecimento em uma rede elétrica monofásica residencial utilizando microcontrolador e supervisório ScadaBR

Abstract

The aim of this work is to use a microcontrolled board Arduino Uno with a voltage sensor coupled to one of its analog inputs, performing the monitoring of the presence or absence of voltage in a residential single-phase power grid. These data collected by the Arduino Uno board and sensor are transmitted via the Universal Serial Bus (USB) using the Modbus protocol to the laptop computer with the monitoring software ScadaBR. Such interruptions are recorded in the supervisory software database can generate charts for confrontation with the values expressed in the electricity bill, an amount called the National Electric Energy Agency (ANEEL) as an indicator Duration of individual Interruption per unit Consumer (DIC).
