  • 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.

  • Patent number: 11774472
    Abstract: A transformer area identification method includes: performing data acquisition on all sub-meters and a master meter in an identification domain to obtain a steady-state load, and generating a steady-state load jump curve; and performing load jump feature matching between steady-state load jump curves of all the sub-meters and a steady-state load jump curve of the master meter, and obtaining attribution of the sub-meters with a load jump according to matching results. A method for constructing transformer area line topology is further provided. A load jump identification technique is utilized to acquire a load value of each node in a transformer area power supply network, so as to form a load jump curve for each node. By performing load jump feature matching between load jump curves of all sub-meters and a load jump curve of a master meter, a mounting relationship of a corresponding electric meter is determined.
