The invention relates to a power distribution network fault treatment method and belongs to the technical field of power network management. A platform comprises a fault information acquisition system, a fault information study and judgment system and a fault clearing and power failure/supply information push system. The method is characterized by acquiring information of faults requested to be cleared, line faults and consumption acquisition faults in an existing 95598 system, a distribution automation management system and a power consumption information acquisition system, after receiving and verifying the information, carrying out equipment locating, fault information screening, line topology analysis, equipment operation information analysis and line switch analysis to determine and display the fault types, places and areas of influence in an existing GIS (geographic information system), guiding fault clearing according to the determined fault results and simultaneously pushing the power failure information and power restoration information to users. The platform and the method can be used for achieving centralized acquisition and advanced automatic study and judgment of existing various fault information, can be used for actively pushing the power failure and power restoration information to the users and can interact with the users.
