摘　　要：智能分布式馈线自动化是近年来提出的新型馈线自动化模式,具有无需主站参与、就地判断、自动恢复非故障区间供电的特点。目前智能分布式馈线自动化主要依靠光纤、5G等通信方式组网,但受光纤、5G信号覆盖范围的影响,应用范围受到一定程度的限制,同时在光纤断线、无线信号强度弱时存在终端之间通信受阻风险,造成自动化开关拒动,线路带故障运行。为此提出了基于电力载波的改进型智能分布式馈线自动化策略。该策略采用载波通信拓展了智能分布式馈线自动化实现方式,提高了终端通信的可靠性,改进了智能分布式馈线自动化故障判断及自愈策略,解决了传统分布式馈线自动化存在的问题。Intelligent distributed feeder automation is a new type of feeder automation mode proposed in recent years,which has the characteristics of on-site judgment and automatic restoration of non fault section power supply without the involvement of the main station.At present,intelligent distributed feeder automation mainly relies on communication methods such as optical fiber and 5G to form the network.However,due to the influence of the coverage range of optical fiber and 5G signals,the application range is limited to a certain extent.At the same time,there is a risk of communication obstruction between terminals when the optical fiber is disconnected and the wireless signal strength is weak,resulting in automatic switch action and line fault operation.In order to solve these issues,this article proposes an improved intelligent distributed feeder automation strategy based on power carrier technology.The new strategy adopts carrier communication to expand the implementation of intelligent distributed feeder automation,improve the reliability of terminal communication,improve the fault diagnosis and self-healing strategy of intelligent distributed feeder automation,and solve the problems existing in traditional distributed feeder automation.
