Transformer area user-transformer relation identification method and system

The invention discloses a transformer area user-transformer relation identification method and system. The method comprises the following steps: acquiring line loss state information of a target transformer area in a certain time period; according to the line loss state information, judging whether the line loss of the target transformer area is normal or not, and if not, obtaining the transformer area loss electric quantity; if yes, ending; performing correlation calculation on the lost electric quantity of the target transformer area and the lost electric quantity of the associated transformer area to obtain a first correlation result, and taking the associated transformer area of which the first correlation result is smaller than a set value as a selected transformer area; performing correlation calculation in the target area and the selected area to obtain a second correlation result and a third correlation result; the user with the second correlation result smaller than a set value serves as a first sele
