The invention provides an electric energy meter metering error estimation method and equipment based on a floating line loss model. The method comprises the following steps: mathematical modeling is carried out on an electric meter error of a transformer area based on energy conservation and floating line loss, and the total electricity consumption of the transformer area is the total meter metering electricity quantity; associating the line loss with the total electricity consumption, and establishing floating line loss; and adopting a solution space constraint least square algorithm to solve the metering error of the electric energy meter in the transformer area in real time. According to the method, the metering error of each user electric meter in the transformer area is solved by using the solution space constraint least square algorithm through the multiple groups of transformer area power consumption data, the function of monitoring the metering error of the transformer area electric meter can be reali
