Method and device for generating power utilization characteristic portrait of transformer area

The embodiment of the invention discloses a method and a device for generating a power utilization characteristic portrait of a transformer area. The method provided by the invention comprises the following steps: acquiring a transformer area number, wherein the transformer area number is a unique identifier of a transformer area; querying a first-level feature tag which reflects power utilization features of the transformer area in multiple dimensions according to the serial number of the transformer area; determining at least one second-level feature tag according to the first-level feature tag; and filtering and comparing a label value in a first preset time and a label value in a second preset time corresponding to the secondary characteristic label to generate an electricity utilization characteristic portrait of the transformer area, the label value in the first preset time and the label value in the second preset time being overload electric quantity in a certain period of time. The power utilization c
