O aterramento ressonante como proposta para melhorar a continuidade no fornecimento de energia elétrica

Abstract

On the search of improvements in the quality of power supply, new technologies in the electrical system are constantly explored and adopted. The grounding systems during normal operation do not have much influence, however the chosen topology defines the power system behavior during faults. This paper aims to present the behaviors of different grounding topologies during a fault occurrence and to highlight the benefits of using resonant grounding. To perform the simulation was made the modeling of the components of a power system in textit software ATPDraw. Results show that resonant grounding eliminates high fault currents. Some disadvantages are found in the application of this topology, such as the cost of the reactor and the neutral overvoltage during the fault. However, this type of grounding brings safety to the distribution networks by controlling the magnitude of the fault current.
