Data input module 1 stores preset power consumption data, theoretical line loss rate data and real-time power consumption data on a monthly basis. The preset power consumption data includes basic information such as customers, transformers, lines and recorders, and Number, name, attributes and other data, real-time electricity consumption data includes power supply and electricity sales data;

Calculation and evaluation module 2, calculate the power loss value and actual line loss rate data according to the preset power consumption data and real-time power consumption data, and calculate the line loss difference rate data and differential power according to the theoretical line loss rate data and actual line loss rate data value, and judge whether the line loss rate in the station area is reasonable;
