The method comprises the following steps of: acquiring data of intelligent electric energy meters in a transformer area; intelligently identifying a power failure branch line or a user; and analyzing and comprehensively judging the alarm of the metering master station. Customer power failure events are collected and analyzed based on the edge computing technology, power failure alarm data are comprehensively verified through operation data of the intelligent metering terminal on the edge side and uploaded to the metering automation master station, the metering automation master station carries out multi-dimensional comprehensive analysis and judgment, and therefore the accuracy of power grid power failure recognition is improved, and the power failure recognition efficiency is improved. The requirements of dispatching power distribution network fault monitoring and first-aid repair and power supply quality reliability are met.

Description

technical field [0001] The invention belongs to the technical field of alarm monitoring, and in particular relates to a quasi-real-time monitoring method and system for power outage events based on edge computing. Background technique [0002] At present, the existing user power outage modeling technology is affected by some factors, mainly including the uncertain relationship between affected users, terminal performance quality, communication quality of collection points, power outage data supplementary collection mechanism, and power outage event judgment rules, etc. Moreover, all power outage-related events are analyzed and judged by the master station, and there are problems such as low calculation efficiency, false positives, and missed negatives. In view of the above phenomenon, an effective model algorithm is needed to migrate the data calculation and analysis tasks from the main station to the terminal equipment on the edge side, effectively reduce the calculation ta...
