Line loss control system

The invention belongs to the field of a power system and automation and particularly relates to a line loss control system. The system comprises a data acquisition unit, a processing control unit and an output display unit, wherein the acquisition unit is used for acquiring basic data for line loss calculation; the basic data comprises equipment parameter information, equipment state data, actually measured data, state estimation data and electric quantity data; the processing control unit is used for receiving the basic data acquired by the acquisition unit and carrying out online calculation and result analysis on an actually measured load, line loss, network loss and the like; and the output display unit is used for receiving and displaying calculation and result data of the processing control unit. According to the line loss control system, multi-dimensional network loss management, normalized load actual measurement, multi-dimensional online statistics on the line loss rate and calculation analysis and m
