Abstract: In the existing verification methods of low-voltage distribution network topology, most of smart meter voltage sequence data of customers in the most recent period of time are extracted from the Advanced Metering Infrastructure (AMI), and the correlation between the voltage sequence data is calculated to measure the similarity between voltage sequence profiles of different customers. However, the existing Local Outlier Factor (LOF) detection algorithm cannot detect the outliers. Therefore, a low-voltage distribution network topology verification algorithm based on ring outliers factor (ROF) detection algorithm is proposed in this paper. ROF algorithm verifies the customer with inaccurate connection of the transformer by correlation coefficient of voltage sequence data, and analyzes the degree of abnormality in the customer's ring domain, which can effectively verify the topology connection between the customer and the transformer in the GIS system.
