Power distribution network power failure event analysis method and device and storage medium

The invention discloses a power distribution network power failure event analysis method and device and a storage medium, and the method comprises the following steps: obtaining multi-source businessdata from all levels of business systems of a power distribution network, wherein the multi-source business data comprises the real-time operation data and alarm signals of all levels of business systems; carrying out hierarchical study and judgment on the multi-source business data to obtain power failure events, and dividing the power failure events into deterministic power failure events and undeterministic power failure events; performing signal priority judgment on the deterministic power failure event and the undeterministic power failure event according to a preset priority rule, and outputting a corresponding power failure event decision result according to a judgment result. The limitation of existing power failure event analysis can be made up, and the accuracy of a power failureevent decision result is
