A New Feeder Automation Scheme Implementing Single-Line-to-Ground Fault Location with Novel Smart Fault Indicators for China's Electric Distribution Networks

This paper introduced a new feeder automation (FA) scheme implementing single-line-to-ground (SLG) fault location with novel smart fault indicators (SFIs) for China’s electric distribution networks (EDNs). When the novel SFI detected a reverse SLG fault, it will send a sequence of event (SOE) via 4G to the distribution automation system (DAS) master station. The DAS master station locates the SLG fault section based on the SOEs from the SFIs. This FA scheme is tested hy the artificial SLG faults in the Joint Laboratory for Intelligent Application and Key Equipment of Distribution Network of State Grid Corporation of China by the Electric Power Research Institute of State Grid Henan Electric Power Company.
