A low-voltage distribution network topology self-healing identification method based on complex impedance space-time evolution constraint comprises the following steps: perturbation characteristic synchronous extraction of multi-source heterogeneous data flow; complex impedance fingerprint modeling based on dynamic current grading; global mapping residual analysis of topology-impedance coupling; topology self-healing optimization based on heuristic evolution algorithm; topology identification verification based on residual analysis. The application excavates the internal mapping relationship between end node voltage, current time sequence characteristics and physical path impedance, and constructs a progressive verification system of "dynamic current grading-complex impedance characteristic fingerprint-global voltage field residual". The core logic is to shield nonlinear interference by using current grading, extract unique complex impedance "fingerprint" as physical constraint, and thus convert the complex topology identification problem into an optimal path search problem of solving the global voltage deviation minimum value under the space-time constraint set.
