【 摘 要 】

Considering that the information uploaded by distribution terminal is often lost or wrong in actual operation, which leads to misjudgement, this paper proposes a new fault location method based on multi-source information fusion technology. The advantage of this method is that multi-source information is used for fault location, which can avoid misjudgement caused by an abnormality of single source information. Firstly, the information uploaded from the remote terminal unit of the distribution automation system is used, and the user complaint information is converted into binary information. The fault information is formed based on the improved binary particle swarm optimization algorithm, and then the improved D-S evidence theory is used to fuse the positioning results of each fault information to obtain the final positioning result. The case study shows that the proposed method is effective and feasible, and can solve the problem when multi-source heterogeneous fault information has unrecognizable anomalies.
