Active power failure monitoring method and system for low-voltage transformer area in distribution network

The invention discloses a power failure active monitoring method and system for a low-voltage transformer area in a distribution network, and the method comprises the steps: obtaining multi-source information data of the low-voltage transformer area in the distribution network through accessing a big data platform; establishing a data operation platform to perform data modeling processing on each data source of the multi-source information data to obtain power failure associated data; performing voltage and current fault automatic monitoring analysis on the metering current and voltage operation data to obtain power failure fault type alarms, and eliminating power failure false alarms in the power failure fault type alarms to obtain current power failure alarms; and on the basis of the event merging priority and the power failure associated data, carrying out power failure event collection confirmation on the current power failure alarm to obtain a confirmed power failure event, and sending a power failure ea
