Prototype industrial system for monitoring electrical parameters of power supply quality/Prototipo de sistema industrial para monitoramento de parametros eletricos da qualidade de fornecimento de energia eletrica/Prototipo de sistema industrial de control de parametros electricos de calidad del suministro electrico

The quality of electricity supply is based on the continuity of the service, addressing interruptions caused by protection devices, network defects or maintenance activities (KAGAN; ROBBA; SCHMIDT, 2009). According to Faias and Esteves (2013), three main aspects are considered: continuity of supply, voltage quality and commercial quality. This aims to meet customer expectations and guarantee minimum levels of service quality. Monitoring the electricity network is essential for analyzing outages and assessing the continuity of the energy supply. The aim of this work is to develop a prototype industrial system for monitoring electrical parameters and the quality of the electricity supply. The system must acquire electrical parameters, process this data and send it for storage, allowing graphs to be generated with the parameters collected. This work also details the steps required to create the hardware and firmware prototypes, as well as the script for storing the data collected. As a result of the validation tests carried out during implementation, graphs generated from the collected measurements will be displayed and compared with measurements obtained from a commercial meter. Finally, the data obtained shows that the prototype system developed is capable of monitoring electrical parameters and the quality of the electricity supply, when compared to a commercial energy analyzer.

A qualidade do fornecimento de energia eletrica se baseia na continuidade do servico, abordando interrupcoes causadas por dispositivos de protecao, defeitos na rede ou atividades de manutencao (KAGAN; ROBBA; SCHMIDT, 2009). Segundo Faias e Esteves (2013) sao considerados tres aspectos principais: continuidade do fornecimento, qualidade da tensao e qualidade comercial. Isso visa atender as expectativas dos clientes e garantir niveis minimos de qualidade de servico. O monitoramento da rede eletrica e essencial para analisar interrupcoes e avaliar a continuidade do fornecimento de energia. O presente trabalho tem como objetivo o desenvolvimento de um prototipo de sistema industrial para monitoramento de parametros eletricos e da qualidade de fornecimento de energia eletrica. O sistema deve adquirir os parametros eletricos, processar esses dados e envia-los para armazenamento, permitindo a geracao de graficos com os parametros coletados. Neste trabalho tambem sao detalhadas as etapas necessarias para criacao do
