The invention discloses a method for controlling the line loss rate of a station area, comprising the following steps: a distribution transformer arrangement step for reducing the theoretical line loss rate of the station area, a distribution network configuration step, a distribution transformer calibration step, a reactive power compensation step, a meter configuration step for reducing the management line loss rate, a line loss analysis step and a power consumption inspection step. The technical effect is: this paper analyzes the reasons and designs the countermeasures from two angles of managing line loss rate and theoretical line loss rate, It is helpful for the subsequent power consumption inspectors to analyze the abnormal situation of line loss rate in the station area, and to formulate countermeasures from the management and technical point of view, which can effectively reduce the level of line loss rate in the existing station area and enhance the professionalization of lineloss management in the station area.
