In order to overcome the limitations of complexity and large scale in the conventional operational inspection process of distribution networks,a fault localization model was proposed by combining information correction and Boltz-mann approach,and verification was carried out through simulative analysis and practical application.The results show that the localization time cost for a single fault node is mostly less than 2 s with the number of iterations less than 40.In multi-fault and multi-distortion cases,the proposed model is superior to the selected reference algorithm with an average localization time cost of 2.45 s.In the practical application of large-scale distribution network operational inspection,the model can detect 365 faults within 15 days with a correction rate of 92.33%no missed detection.The model performs well in terms of fault detection efficiency and maintains a localization deviation of less than 5 m.
