Research and Application of Multi-Point Feeder Automation For Overhead Lines In Intelligent Distribution

At the present time, Distribution automation FA deployed at the outgoing intervals of the substation, In the event of a fault on the line, the fault is isolated by tripping the outgoing switch at the substation,But, Easily expanding the scope of fault when complex lines are involved, At the same time, the substation outgoing interval data can not be effectively direct mining led to distribution network,so, FA can not be put into normal operation, further resulting in an increase in the number of power outage users, In order to address the above issues, Deployment of FA on smart 5G switches with three-remote function for 10kV lines in distribution networks, And redesign the launch strategy of the FA, The occurrence of 5G switch tripping necessitates the implementation of protective measures on the line as the FA start condition. When faults accurt, Isolation of faults in close proximity by the 5G switch on the line, Reducing the scope of power outages. The program has been put into use in one of the Chinese districts with remarkable results
