Abstract: Aiming at the unsatisfactory route selection result of traditional single grounding fault line selection device, this paper analyzed the development trend of small current grounding fault line selection system in intelligent substation and proposed a new kind of small current grounding fault line selection system. This system combined the intelligent substation composition structure with data transmission characteristics and finished the line signal acquisition through the interlayer protection device. By using the GOOSE message transmission mechanism through the station control layer network, the line signal was sent to the fault line selection device for fault judgment. The simulation results show that this system can judge the fault line quickly and correctly.
Key words: small current grounding fault line selection; GOOSE transmission mechanism; simulation test; accuracy
