Abstract:In order to solve the problems of high loss rate of the platform area and low distribution efficiency in the power system, the paper conducts an overall research on the electricity consumption information collection system, and combines the collected actual data and theoretical data to design the station area line loss analysis platform to analyze and study abnormal line losses. To verify its effectiveness, an abnormal line loss case analysis of a power supply company was used to verify the feasibility and effectiveness of the technology. Analyze the causes of abnormal line loss of 0.4kV and 10kV partial voltage lines, and combine the actual situation of the region and the theoretical line loss data, put forward targeted solutions to provide a scientific basis for the line loss management of power companies.
Key words:analysis platform; line loss in station area; multi-source data complementation; distribution network
