Power consumption abnormity monitoring method and system based on big data analysis

The invention discloses a power consumption abnormity monitoring method and system based on big data analysis, and particularly relates to the technical field of power consumption abnormity monitoring, and the processing method comprises the following steps: obtaining similar information, replacement time information and power consumption abnormity information of equipment, building an equipment matching index, evaluating equipment in other regions, and determining the power consumption abnormity of the equipment. The equipment with the highest matching degree with the newly-replaced equipment in other areas is screened out, the power utilization abnormity monitoring strategy is applied to the newly-replaced equipment, the situation that the original overall monitoring strategy is vulnerable due to sudden replacement of the equipment is avoided, and the power utilization abnormity monitoring accuracy is improved; the power consumption data information of the equipment in the area is obtained, the comprehensiv
