Electric Power Distribution System Topologies: Radial, Ring, Parallel
An electric power distribution system can be classified based on the configuration of its feeder connection schemes, also known as
Ring network distribution network relay protection
In the ring distribution network, differential relays, which rely on communication between the protection relays, are used for the underground cable protection. To guarantee cable protection when communication is failed, an auxiliary protection by using directional overcurrent. This article introduces a new approach for validating directional overcurrent protection schemes in ring-topology electrical distribution systems with distributed energy resources (DERs). The proposed protection scheme incorporates overcurrent and directional functions and addresses DER-induced. The use of ring circuits in 6 – 35 kV distributed electrical networks can improve the reliability of power sup-ply. An incre...
