Research on the network reconfiguration after distribution network fault

For the problem of the distribution network reconfiguration. This article describes the three network reconfiguration scheme. Adhere to the principle of “Step by Step” and gradually upgrade, the automation level of a system can be enhanced. The local intelligence mode is a foundation function, it is easy to implement without the communication system and the host station. On the basis of the local intelligence mode, it can automatically upgrade to distributed intelligence model and improve the automation level through adding the communication channels. When monitoring and controlling the line perfectly are needed or network structure is complex, the comprehensive automation of feeder can be realized by building the distribution control center and improving the channel of communication.
