Item Desenvolvimento de Estudo de Proteção para Conexão de uma Usina fotovoltaica de 1.194kWp(2023-09-21) Oliveira, Maria Eduarda Araújo de; Alves, Denis Keuton; Ando Júnior, Oswaldo Hideo; https://lattes.cnpq.br/7109075850257262; https://lattes.cnpq.br/8911684468319565The generation of photovoltaic energy presents a different profile from the generation of conventional energy (hydroelectric). This is due to the characteristics inherent to the photovoltaic generation process, such as intermittent generation, in which fluctuations in energy generation occur, adding greater complexity to the protection system. Therefore, this work analyzes current regulations and recommendations for preparing a study on the protection and selectivity of photovoltaic generators. This work used a real case study with a 1MW generator connected to the local utility through a coupling transformer and inverters. The protections and adjustments were selected to assess the reliability of the proposed generator and ensure connection to the distribution network with the minimum quality parameters required by regulations. From the results obtained, it was verified through graphic analysis of the coordination that the method used was effective in the protection and selectivity study, attending to current regulations.
