TL;DR: In this paper, a power impedance topological graph generation method and system for a power distribution area is described, and the method comprises the steps: firstly obtaining the A/B/C three phases of the power distribution transformer side and the time sequence voltage data of each user load node, determining the phase relation of each load node through a K-means clustering method, and constructing a feature coefficient matrix for the divided three phases; generating a single-phase topological adjacency matrix of the transformer area with line impedance information and geographic information coordinates to form an electric
