Medium-voltage Distribution Feeder model and network topology

Some of the inherent features of electric distribution systems are that the system includes an extremely large number of equipments and few links between different feeders. Based on these features, a network topology algorithm feeder oriented is proposed in this paper. A Circuit is a collection of conducting equipments, branch-circuits, and pole-mounted switches and is divided into a number of feeder segments by section switches. A Circuit generally starts with a switching device, located in a substation to an open switch (radial circuit), or to a second substation (ring circuit). It proposes modified models for distribution lines such as Ring, Circuit, and Circuit Section based on the IEC 61968/61970 CIM model. Using these models, topology processing is divided into three steps: feeder Analysis, ring analysis, and network analysis.
