  • Patent number: 11982695
    Abstract: A transformer area identification method determines a corresponding electric meter mounting relationship by identifying a power jump characteristic based on a power statistic of each node in a power supply network of a transformer area, thereby eliminating the influence of line loss power and increasing identification accuracy. In addition, the identification is performed based on change characteristics of unidentified total power and power of an electric meter in a to-be-identified domain, to reduce interference of a power fluctuation of an identified electric meter to the identification and increase the identification accuracy. Moreover, iterative identification is used, so that the to-be-identified domain is smaller and a convergence speed is faster. The transformer area identification method uses a power jump algorithm to identify the transformer area, thereby eliminating the influence of the line loss power and increasing the identification accuracy.
