The theoretical line loss value acquisition module can calculate the theoretical line loss of the power transmission line according to the length, the material, the position and the air temperature of the power transmission line and calculate the line loss of each electrical element according to the model and the working environment of the electrical element, so that the theoretical line loss value acquisition module can calculate the theoretical line loss value of the power transmission line in a selected area according to the known data information of the power transmission line in the selected area. Because the real-time line loss value of the power transmission line in the region may be affected by factors such as actual air temperature, service life of electrical elements, working environment and the like, a certain deviation may occur between the real-time line loss value and a theoretical line loss value, so that a certain voltage loss may be generated in the process of transmitting electric energy by the power transmission line. The real-time line loss value acquisition module calculates the real-time line loss value of each power transmission line according to a real-time voltage drop method, namely calculates the real-time line loss value of each power transmission line according to the voltage drop generated in the real-time transmission process. Through comparing the real-time line loss value of each power transmission line with the corresponding theoretical line loss value, when the real-time line loss value exceeds the preset threshold range of the theoretical line loss value, the line loss monitoring and early warning module can send out early warning information to prompt relevant workers to pay close attention to or take corresponding treatment measures in time, so that the factors causing the line loss of the power transmission lines to be serious are eliminated, the power supply loss caused by the long-time serious line loss is avoided, and the efficiency and the quality of power supply are improved.
