Aiming at the problems of the confusion of user meter data in the distribution network and the difficulty in identifying the relationship, a creative method of identifying the topological structure of the station based on the conservation of current and energy is proposed. Through the calculation of the current data relationship, a mathematical relationship model based on energy conservation is established for the topological scene of the station. After constructing the mathematical model, through a series of transformation methods, the model is transformed into a convex optimization problem. By solving the model, the topological relationship of the station is finally obtained. Through the experimental verification and analysis of real data, the model algorithm proposed in this paper has higher accuracy and higher efficiency than manual screening, and has deeper research value.
