Digital power distribution network fault processing system and method

The invention discloses a digital power distribution network fault processing system and method, relates to the technical field of fault processing, solves the problem of misjudgment caused by the fact that linkage abnormity is not considered, monitors data of different nodes of a digital power distribution network, locks abnormal nodes on the basis of monitored specific values, and improves the fault processing accuracy. Determining whether the abnormal nodes belong to single-group abnormal nodes or linked abnormal nodes; for a single group of abnormal nodes, directly adopting the test current to carry out internal resistance heating test, determining an internal resistance heating curve, and generating and displaying a corresponding processing signal based on the numerical value change of the internal resistance heating curve; and aiming at the linkage abnormal nodes, the synchronous abnormal nodes are preferentially determined, and then gradual testing is carried out, so that other abnormal nodes do not ne
