Desenvolvimento de circuitos para monitoramento do consumo de energia elétrica e auxílio na escolha do tipo de tarifa

Abstract

The white tariff modality was implemented in Brazil to encourage consumption of electricity outside of standard peak hours. The hours of greatest consumption of electricity are priced at different values due to the great demand requested from the generators at these times, requiring an increase in energy production to supply all consumption. It is a fact that forms of monitoring consumption are not distributed by day or hour, only monthly, therefore, in this study, the monitoring of the consumption of electrical appliances was evaluated to visualize the impact of the implementation of the white tariff on the consumer's energy bill. Arduino development board and complementary components were used to measure power, current and voltage in electrical installation circuits, to gather data. For this, two embedded systems were developed to perform the measurements of these quantities and perform the necessary calculations for the validation of the assertion made. To ratify the postulated thesis, tests were carried out to measure the equipment used, prior and definitive implementation of the assembled device. Within the evaluated, it can be observed that the circuits fulfill their objective of measuring current and voltage, generating data to provide the analysis of the implementation of the white tariff in the establishment.
