[0020] Example 1:
[0021] (1) Use the feeder fault processing server to search online, and wait for 10 to 300 seconds after the feeder fault processing server receives the fault information sent by the FTU or the feeder outlet switch protection action information sent by the RTU in the substation. If new fault information or feeder outlet switch protection action information is received within the set waiting time, the waiting time will be reset to zero and the accumulated waiting time will start again.
[0022] (2) According to the records of the switches in the feeder line and the feeder outlet switch status before the fault occurs, use conventional methods to analyze the network topology and draw the network topology analysis conclusion;
[0023] (3) According to step (1) the fault information received from the FTU or the feeder outlet switch protection action information from the RTU in the substation and the conclusion of the network topology analysis obtained in step (2), use ...

[0029] Example 2:
[0030] (1) Use the feeder fault processing server to search online, and wait for 10 to 300 seconds after the feeder fault processing server receives the fault information sent by the FTU or the feeder outlet switch protection action information sent by the RTU in the substation. If no new fault information or feeder outlet switch protection action information is received within the set waiting time, use conventional methods to locate the feeder fault;
[0031] Steps (2) to (8) are the same as in Example 1.
