Fault locating method, device, equipment and storage medium

Abstract

This application discloses a fault location method, apparatus, device, and storage medium, relating to the field of automated operation and maintenance technology. The method includes: collecting the remote signaling status of tie switches in a distribution network and electrical quantity data of the corresponding feeders; if the remote signaling status indicates a closed state, determining whether a high-resistance path anomaly exists in the tie switch based on the electrical quantity data; if a high-resistance path anomaly exists, correcting the topology model of the distribution network to an open-loop model; and locating the fault section in the distribution network based on the corrected topology model, generating a fault section location result. This application further detects tie switches characterized as closed states using actual electrical quantity data to determine whether they are truly closed to form an effective path. When a high-resistance path anomaly is determined in the tie switch, the topology model is corrected to conform to the actual distribution network state, thereby ensuring accurate subsequent fault section location.
