Design of Distribution Network Feeder Automation Terminal System
The traditional feeder automation system has the problem of imperfect monitoring function,which will lead to frequent and large-scale power outage due to delayed fault processing.Therefore,based on the combined application of intelligent terminal feeder equipment and main station,this paper designs a new feeder automatic terminal system.This system has both local and remote control functions,and can implement relay protection and mechanical performance monitoring with the support of new feeder terminal units.It can also monitor multiple parameters such as contact displacement,opening and closing speed during switch switching in real time,timely detect and effectively deal with switch safety hazards,reduce the occurrence of power outages,and promote the automation development process of the distribution network.
