Item Impactos da inserção de geração distribuída no desempenho de funções de proteção de sistemas elétricos(2019-07-17) Guerra, Keylla Rayanne Albuquerque; Reis, Raphael Leite de Andrade; http://lattes.cnpq.br/1139577841043865; http://lattes.cnpq.br/8938549432716009From the need to expand the electric generation due to population and industrial growth, the connection of Distributed Generation (DG) with the electrical system has increased due to its several advantages, such as: minimization of transmission losses over long distances, location near consumer centers, minimizing environmental impacts and greater reliability. Despite being a trend, challenges to the protection system are imposed as contributions to short circuit currents may become more evident with the GD connection. In order to investigate the impact of GD on electrical power system protection functions, fault simulations were performed in the Alternative Transients Program (ATP) software, considering a 230 kV network reported in the literature. Short circuits were simulated along the evaluated power system as well as near the distance protection zone reaching, taking into account different types of disturbances. From the obtained results, the insertion of GD can affect the voltage and current signals measured by the protective device, as well as protection functions, leading them to misoperate if revisions on their adjustment settings are not performed.
