The invention belongs to the technical field of power supply management, in particular to a method for quickly distinguishing transformer area user-transformer relations. The line loss electric quantity and the user electric quantity are analyzed by using a Pearson correlation coefficient method; particularly, correlation analysis is carried out on a negative loss transformer area, abnormal userscan be quickly found, the number of field check users is reduced, a user marking unit is designated as a unit, the unit is a meter box (generally one meter box represents the same power supply point,namely the same transformer area), the daily power consumption of the meter box is calculated according to the relationship between the meter box and the users, and then the transformer area relationship of the user meter box is checked; a 'genetic algorithm' is adopted to solve a 'combination problem', one population has a plurality of individuals, and each individual has a chromosome and a corresponding gene and is similar to a knapsack problem in the genetic algorithm.
