In order to improve the practicality of feeder automation, this paper adopts the hierarchical and divisional configuration scheme of feeder automation according to features of the distribution network. The feeder automation is divided into three layers from bottom to up: feeder layer, feeder island layer and system layer. On the feeder layer and the feeder island layer, different feeder automation schemes are suggested based on the regional characteristics. The FA mode without communication which is simple and reliable is adopted in the single power line. This paper combines the reclosing the breaker twice with opening the loader breaker to isolate the fault of the feeder’s branch line. A distributive and intelligent feeder automation method based on the sum of fault signals is proposed, which is simple and intuitionistic. This method is able to transform the judgment logic automatically between contact switch and section switch and adapt to the adjustment of the operating mode flexibly. On the system layer, this paper uses network topology and optimization operating to improve the reliability of power supply when the failed main network causes widespread power outage through the power supply of distribution lines. Furthermore, this method can optimize the network operating and reduce the power outage.
