Bayesian model-based medium-voltage distribution network topology correction method

The invention discloses a medium-voltage distribution network topology correction method based on a Bayesian model. Relates to the technical field of operation and maintenance of power distribution networks, in particular to a method for topology correction of a power distribution network. According to the method provided by the invention, a judgment coefficient is extracted by utilizing a linear relation between voltage and power in a line, a Bayesian model is established according to a topological structure of the power distribution network, remote monitoring of a topological state is realized by processing online data, and in combination with previous records, rapid positioning is realized on actual positions which are not consistent with the records in topology, and a topology correction scheme is given. Under the condition of frequent line replacement, branch circuits with problems in the topological structure in the medium-voltage power distribution network are checked and corrected, the working efficie
