DETECTION TECHNIQUE OF FAULT LOCATION IN DISTRIBUTION SYSTEM BASED ON DISTRIBUTION AUTOMATION SYSTEM

摘要

Ground fault in 23 kV distribution systems be related to a kind of method and apparatus be used to calculate distance the distribution lines to breakdown point only the present invention in the case of being withdrawn from from electric substation, predetermined position of the terminal device in the distribution substation and distribution lines for being mounted on distribution system, it remotely obtains operation information, using first is that the distribution system automated, when the ground fault in the distribution wire of waveform information that analysis is stored in these terminal devices is characterized in that calculating distance to from electric substation to the fault point of the distribution wire of the take-off stage in a central processing unit
