The current fault section positioning method in distribution networks faces challenges in accurately locating fault segments when a large area of measurement data is missing or distorted at distribution terminals. Therefore, a method for locating high-fault-tolerant fault segments in distribution networks based on multi-source information fusion and verification is proposed. Firstly, the electrical characteristics of measurement information are used to divide Feeder Terminal Units (FTU) and Transformer Terminal Units (Transformer Terminal Units). TTU) and the reliability level of the electricity meter in the station area, so as to reduce the dimension solution space, and use remote measurement to verify the remote signal quantity of FTU and TTU with low reliability to reduce the occurrence of misjudgment; Then, the basic distribution probability of the fault hypothesis variable was calculated by the distortion information sequence, so as to account for the influence of missing and false positives on the location results. The location results were verified by the consistency of the segment and port location results, so as to make the location results more accurate. Finally, an example is provided to demonstrate the superiority of the proposed method in terms of convenient implementation and robust fault tolerance, especially in scenarios involving multi-information distortion.
