Problems solved by technology

[0003] 1. There are many types of equipment in the low-voltage distribution area, and the large number leads to low efficiency of line loss analysis: the power supply department often needs to measure and calculate the equipment in the area one by one, although this can improve the accuracy of the analysis to a certain extent. However, this repetitive mechanical redundant work is not simple enough, which reduces the work efficiency of the enterprise

[0004] 2. The existing line loss analysis methods mostly use various simplified and approximate theories, such as the clustering method and regression method of load statistics, etc., but there are still low precision and inaccurate situations

[0005] 3. The existing methods for the screening and analysis of typical station areas lack systematic standards, are subjective, cumbersome, and inefficient, and are prone to errors and omissions. Comprehensive Analysis and Evaluation
