Uma estratégia de retrofit para monitoramento de parâmetros elétricos em tempo real com base no metamodelo SmartLVGrid

Abstract

Electric energy management enables the planning and efficient use of this input to improve competitiveness, sustainability and to reduce costs to the final consumer. In addition, the Internet of Things (IoT) paradigm promotes the emergence of remote monitoring solutions to enable strategies for this type of management. However, these solutions can favor the disposal or replacement of outdated systems, but still necessary. Thus, a reference model that advocates the retrofit of pre-existing systems would be an alternative to implement monitoring resources to enable energy management. In this sense, this work presents a strategy for monitoring electrical parameters in real time from the retrofit of legacy electrical systems. This strategy consists of adapting the SmartLVGrid metamodel to systematize the insertion of remote monitoring resources in low voltage electrical circuits. Thus, the aim is to analyze the electrical parameters in the context of energy efficiency and energy quality. To validate the proposal, real-time embedded platforms were developed for monitoring the circuits of a power distribution board, integrated into a software application for visualization and storage of data in the cloud. In this way, this work presents an alternative to enable energy management through remote monitoring and maximum use of pre-existing resources. The results obtained present the individual monitoring of electrical parameters, energy demand, power factor and events associated with variations in product quality in the circuits of the legacy distribution board.
