Resumo-O presente trabalho apresenta uma metodologia para detecção, a partir de imagens, de quatro tipos de isoladores utilizados em redes de distribuição aéreas de média tensão (RDAs). Para isso, foi utilizado o dataset OPDL, que possui imagens de isoladores íntegros e defeituosos em ambiente externo e em ambiente controlado (laboratório), como entrada para os detectores baseados em Deep Learning (DL). Foram utilizadas diferentes variações da arquitetura You Look At Once Versão 5 (YOLOV5), que foram avaliadas considerando sua influência na melhoria da acurácia de detecção dos isoladores e no tempo de resposta. Os resultados obtidos mostram que o detector proposto oferece alta acurácia e uma rápida resposta.
Hybrid energy production systems provide greater stability, constancy and reliability to the generation system by implementing different energy sources. However, there are technological and regulatory challenges that need to be overcome. The article aims to present the concept of technology applied at a global level, through a literature review of patents published in the last five years. Identifying hybrid power generation systems with varied configurations and arrangements between energy sources. The high potential for expansion of the hybrid plant can be seen in the creation of technologies and development of control systems, aiming at future consolidation in the energy market.
