Based on the advanced metering infrastructure （AMI） user measurement data, this paper aims solve topology verification of city LV power distribution network. Firstly, the typical structure of city lv power distribution network was analyzed, and belonging topology and phase topology were defined. Then the topology verification models were researched, including circuit model and math model, and the method of multi-variate linear regression is studied. Combining the power network operation, topology verification framework was given, and the detail verifications of belonging topology and phase topology were proposed. Finally, taking the three typical communities in Hefei as an example, the verification results were demonstrate. The example shows that the accuracy of belonging topology verification is 100%, and that of the phase topology is 95%.
