7. a kind of fault location system based on platform area circuit topology relationship according to claim 2, which is characterized in that institute
Stating time interval is 100ms.
8. the Fault Locating Method based on any system described in claim 1-7, which comprises the following steps:
1) detection module, level-one collection module, second level collection module and center identification are installed at custom power data collection layer
Processing module.
2) voltage of detection module detection user terminal, current data, and address information is generated, detection module is to same time interval
5 groups of data be averaged, be compared with corresponding rated value, limiting value, then information of voltage stream and electric current believed
Breath stream is tentatively judged；It divides into emergency data stream and abnormal data flows to upper level upload.
3) the first collection module handles abnormal data stream, and generates detection module abnormal data stream, and on upper level
It passes.
4) the second collection module handles emergency data stream, and generates detection module abnormal data stream, and on upper level
It passes.
5) central recognition processing module carries out unpacking processing to fail address and detection module exception number address information.
9. Fault Locating Method according to claim 8, which is characterized in that the first collection module carries out abnormal data stream
Preliminary wrong report judgement；Second collection module carries out preliminary wrong report to emergency data stream and judges not.
10. Fault Locating Method according to claim 9, the wrong report judgement are specially；Level-one collection module will be abnormal
Voltage and current data flow handled；Voltage and current data in the same time are subjected to logical operation and obtain P1,
The rated power of user's incoming end is Pz, and the power limit of user's incoming end is Pmax, as Pmax >=P1 >=0.95%Pz, one
Abnormal voltage and current data stream and address packaged data are sent second level collection module by grade collection module；As P1 >=Pmax or
Person 0.95%Pz >=P1 does not send data to second level collection module.
