The invention discloses an adaptive local type feeder automation fault processing method based on the area serial number, which comprises the following steps: the area range is delimited; The circuitbreaker at the outlet of the substation is connected to the contact switch, and the end of the line is delimited as a logic area; A logical sequence numb is allocated, and that segment switch in eachlogical region independently allocates the sequence number; Switch is provided with unified parameter; Adaptive adjustment of operating parameters is preformed; fault isolation is performed; restore power to non-faulty areas is performed. after the method of the invention is applied, when the distribution network is affected by the changes of the network topology such as the newly added branch lines and the adjustment of the multi-connection operation modes, the original tuning parameters are not considered to be changed, and the automation system can be adaptively operated. At the same time,when the terminal algorithm can not identify the fault due to the large grounding transition resistance, the method can cooperate with the centralized grounding line selection trip or manual trip in the substation to complete the isolation and recovery operation of the high-resistance grounding fault.
