Low-voltage distribution network topology identification method based on GIS and voltage waveform correlation analysis

The invention belongs to the technical field of low-voltage power distribution networks, and particularly relates to a low-voltage power distribution network topology identification method based on GIS and voltage waveform correlation analysis. The method comprises the following steps: firstly, acquiring GIS data and voltage data, then preliminarily evaluating the topology of a power distribution network based on the user longitude and latitude of a GIS and the power distribution transformer longitude and latitude of a transformer area, determining the user-transformer relationship of a non-overlapping area, then calculating the similarity between the user voltage and the power distribution transformer voltage of an adjacent transformer area for the overlapping area, judging that the user belongs to the transformer area, and judging that the user belongs to the transformer area. And finally, dynamically monitoring the transformer area change condition of the overlapping area. According to the low-voltage dist
