Method and device for monitoring and judging voltage loss of plant station, equipment and storage medium

The invention discloses a method and a device for monitoring and judging voltage loss of a plant station, equipment and a storage medium. The method comprises the following steps: acquiring the system voltage of a plant station; determining whether the system voltage of the plant station meets a voltage loss judgment starting condition or not, wherein the voltage loss judgment starting condition comprises that the system voltage is changed to be lower than a voltage loss threshold value within a preset time interval and the duration that the system voltage is lower than the voltage loss threshold value exceeds a preset duration; if yes, when the plant station is not in the whole-station maintenance state, determining whether the system voltage meets a preset voltage loss rule and a preset false alarm rule or not, wherein the preset voltage loss rule comprises that the system voltage is lower than a voltage loss threshold value and the duration exceeds a preset duration, and the preset false alarm rule compris
