Abstract
The invention discloses a lightning stroke failure disconnection positioning method based on information interaction. When lightning stroke failure occurs on a power transmission line, the geographic position of the lightning stroke breakpoint can be positioned by collecting section switch voltage data, tapping switch voltage data and intelligent meter voltage data, judging the collected voltage data, inputting the judged abnormal data to a geographic information system (GIS) system and combining line device topology information in the GIS system. By means of the lightning stroke failure disconnection positioning method, real-time monitoring and geographic positioning on the lightning failure can be achieved, time, labor and cost for line maintenance are greatly reduced, simultaneously safety hazards caused by all factors like the fact that the lightning stroke breakpoint cannot be judged from the outside of the cable and working staff are not careful can be avoided, and safety in power transmission is effectively improved.
