Realization of Intelligent Distribution Loop Service Mode in Urban Distribution Power Network

Combined with the project example of cable network retrofit in Guangzhou south district, the automation retrofit scheme of intelligent distribution loop service mode was introduced, which was formed by adopting intelligent swftchgear (such as re -closer and intelligent switchgear of ring - operated network). The structure and operation mode of the loop service network were introduced, and the implementation method of network for feeder line automation intelligent distribution was discussed. The practice shows that the intelligent distribution bop service mode in urban distribution power network based on the concept of local protection is economic and feasible.
