Abnormality detection method and device, electronic equipment and storage medium

Abstract

The invention discloses an anomaly detection method and device, electronic equipment and a storage medium, and the method comprises the steps: collecting the state measurement information of an isolation knife switch at the current moment, and obtaining the knife switch state information of the isolation knife switch at the previous moment; according to the disconnecting link state information of the disconnecting link at the previous moment, state prediction information of the disconnecting link at the current moment is predicted; determining disconnecting link state information of the disconnecting link at the current moment according to the state measurement information at the current moment and the state prediction information at the current moment; and when the disconnecting link state information at the current moment is matched with a preset disconnecting link abnormal condition, abnormal alarm information is generated and an alarm is given. According to the scheme, the accuracy of state determination of the isolation switch is ensured, so that the position of the isolation switch is accurately detected, distribution faults in the power distribution process of a power distribution network caused by misjudgment of operation and maintenance personnel are avoided, and the safety of operation of the isolation switch is improved.
