Problems solved by technology

[0003] The conventional implementation mode of feeder automation is the centralized control type, which requires a communication channel and a control master station. The communication system is the link between the master station system and the terminal equipment of the distribution network. When a fault occurs, the control master station receives the feeder terminal ( Feeder Terminal Unit (FTU) collects fault information, locates faults, and issues control commands. All operations are performed by the master station, so the burden on the master station is heavy, and the speed of processing faults slows down. At the same time, the FTU Upload information to the master station, the master station sends control information to the FTU, and the information needs to be transmitted back and forth between the master station and the FTU, which results in prolonged fault

Abstract

The invention discloses a feed line automation system which comprises a main station system, a point-to-point equity communication network and a distribution automation terminal FTU (Feeder Terminal Unit). The FTU connects to the point-to-point equity communication network. The main station system connects with a communication processor CP which connects to the point-to-point equity communication network. The point-to-point equity communication network is used for realizing direct communication between adjacent FTUs. The FTU is used for positioning a fault, isolating the fault and recovering power supply of a non fault section. The CP is used for forwarding FTU data to the main station. The main station receives the FTU data forwarded by the main station, and the data is provided to work personnel of the main station as time processing sequence soe information.

Description

technical field [0001] The invention relates to the technical field of power system automation, in particular to a feeder automation system. Background technique [0002] At present, in order to reduce the failure time of the medium-voltage power grid, the feeder automation has been widely valued by people. Feeder automation refers to the automation of feeder lines between substation outgoing lines and user equipment. It is used for user detection, data measurement and operation optimization under normal conditions, as well as fault detection, fault isolation, transfer and restoration of power supply control under accidental conditions. [0003] The conventional implementation mode of feeder automation is the centralized control type, which requires a communication channel and a control master station. The communication system is the link between the master station system and the terminal equipment of the distribution network. When a fault occurs, the control master station ...
