(602) note abnormalities electrical parameter waveform when, abnormal electrical parameter waveform segment can be sent to exception by waveform segments contrast module (602)
Waveform locating module (7)；
S2, after unusual waveforms locating module (7) receives abnormal electrical parameter waveform segment, unusual waveforms locating module (7) can exist
Corresponding abnormal section is chosen in power distribution network circuit diagram (8), unusual waveforms locating module (7) can send out the circuit diagram abnormal section of selection
It send to real time fail locating module (9), real time fail locating module (9) can search circuit diagram in power distribution network map (10) at this time
The corresponding geographical location of abnormal section, can pass through behind the position that real time fail locating module (9) finds singlephase earth fault
Abnormal positioning is sent to base station processing center (3) by centre processing module (11)；
S3, can be by central processing module (11) by location information and phase after base station processing center (3) receives abnormal positioning
It closes failure to be sent to tasking module (12), location information and dependent failure can be sent to technology by tasking module (12)
Personnel screening systems (13), technical staff's information extraction modules (131) in technical staff's screening system (13) can be from skill at this time
The relevant information of art personal information library (4) extractive technique personnel；
Technical field screening module (132) in S4, technical staff's screening system (13) can sieve unrelated art personnel
It removes, fault distance screening module (133) can filter out the technical staff nearest with faulty section, after technical staff determines, technology
Personnel's determining module (134) can will send information to be sent to corresponding technical staff's task receiving by central processing module (11)
Module (14), when technical staff repairs trouble hunting, technical staff can pass through real time information feedback module (5) typing phase
The failure and repair message answered.
