technical field [0001] The invention relates to the field of electricity safety, in particular to a method for finding line loss problems in low-voltage station areas based on multi-factor state distribution. Background technique [0002] The low-voltage station area is the terminal organization of the power system, involving a huge number of users, and its loss accounts for a considerable proportion of the power grid. At the same time, the operation and maintenance and management workload of the station area is heavy, and it is impossible to achieve full coverage. It is an effective way to alleviate the shortage of operation and maintenance resources by proposing reference guidance for the investigation of abnormal line loss in the low-voltage station area. [0003] In recent years, with the further development of the economy and society, the types of household appliances have become more and more abundant, and the electricity consumption of households has increased signifi...

However, the overall volume of the low-voltage station area is huge, and there are differences in the organizational norms, the number of service users, and the daily transmission power of each station area. The cause of the abnormal loss of the station area has become a difficult task in the daily management of the station area. It is an important indicator to consider the operation and maintenance management of the station area. Therefore, it is necessary to invest energy in researching the method of finding the cause of abnormal line loss in the station area to help improve the pass rate of line loss in the station area.

[0004] In the traditional way, the line loss problem of the low-voltage station area is found by modeling and calculating the line loss. The quality requirements of the basic data of the low-voltage station area are very high, resulting in a limited scope of application of the method, and it is difficult to popularize and apply it in batches.
