The impacts of distributed generation growth on industrial systems protection schemes: Short circuit, coordination, selectivity and arc flash studies

Globally, aiming to supply the continuous growth of the demand for electric power, it has been implemented, more and more, the concept of distributed generation (DG). Although it brings on many advantages, the connection of DG in the electrical power system produces the augmentation of the complexities related to the protection, automation and control of the power system. Considering those issues, this paper sets forth an analysis on the impacts of DG growth on actuals protections schemes in an industry system that doesn't apply co-generation, whereas it is assessed the behavior of the coordination, selectivity and incident energy of arc flash, due to the rise of the short-circuit power at the point of common coupling between the entry bus and the industrial electric power system.
