Research on Line Loss Diagnosis of Low Voltage Station Based on Data Mining Technology

:In view of the huge amount of power data collected at the transformer end of the low-voltage substation area, it is difficult to analyze the line loss.The massive user data accumulated in the process of power information system marketing automation is analyzed in depth, and a reasonable and efficient line loss analysis mathematical model is established. By mining the useful information behind these data in the smart meter, we can detect the user''s abnormal electricity use behavior, and achieve the purpose of preventing electricity theft and leakage, so as to reduce the line loss. Using the weighted LOF algorithm data mining technology of power line power stealing layered detection method, we can analyze the massive user data weighted outliers, and more effectively complete the positioning of abnormal power users.
