The beneficial effects are that:

1. according to the scheme, the electric power network structure to be checked is combed, and the electric power network structure is converged, integrated and segmented according to the preset segmentation strategy by combining different node types, so that the data size of the power supply section of each segment is larger, and each power supply section has enough checking necessity. Meanwhile, the power supply section after segmentation is divided into a first power supply section and a second power supply section by combining the difference of a mains supply power supply node and a grid-connected power supply node. When the inspection is performed, the large-dimension inspection is performed firstly to obtain the first line loss information corresponding to all the first power supply sections and the second line loss information of each second power supply section, when the first line loss information or the second line loss information is abnormal, the fine-dimension inspection is performed, and when the first line loss information or the second line loss information is not abnormal, the fine-dimension inspection is not needed, so that the data processing amount of the inspection is reduced, and the targeted inspection for screening the power system is realized. In addition, after inspection, different inspection labels are added to the power supply sections according to inspection results of different power supply sections, so that workers can be assisted in quickly and efficiently inspecting abnormal information of the power system, and meanwhile, a maintenance strategy is preliminarily and automatically established.

2. When the connection lines formed by all nodes and the power transmission lines in the power network structure are segmented according to the preset segmentation strategy to obtain a plurality of power supply segments, the corresponding power transmission nodes are combined according to the first quantity and/or the sum of the first electric quantity of the power utilization nodes, so that the summary of the power supply lines is realized, and each power supply segment has enough checking necessity. Meanwhile, after the power supply sections are obtained, the power supply main section and the power supply branch section corresponding to each power supply section are determined. When checking, the different modes of calculation are carried out by combining different power supply sections to obtain the line loss information of the corresponding section, and when the line loss information is abnormal, the corresponding checking label and the corresponding abnormal positioning information are generated. Through the mode, the inspection processing amount can be reduced, and meanwhile, the inspection result can be correspondingly output.

3. When the scheme outputs the inspection result, the type of the power supply section is considered to be different, and the plurality of sub-sections in the power supply section are also considered to be different in the required corresponding maintenance group. For example, for grid-connected power supply nodes and mains supply nodes, the corresponding power supply types are different, and thus the corresponding maintenance groups also need to be different. For another example, the voltage intensity corresponding to the power supply main section is larger than the voltage intensity corresponding to the power supply branch section, and the voltage intensity corresponding to the power supply branch section is smaller. Therefore, according to the scheme, different audit labels are added for different power supply sections, so that the corresponding maintenance groups are determined to carry out targeted maintenance. The data processing amount is reduced, and meanwhile, a targeted checking result is output, so that workers are assisted to check abnormal information of the power system rapidly and efficiently.
