基于网络模型的输电线路缓变故障诊断方法
Soft fault diagnosis method of transmission line based on network model
摘要
Abstract
The failure mechanism of soft fault is vague, and fault timely diagnosis is difficult as well as simulation. The soft fault diagnosis method of transmission line based on network model is proposed. The modularity concept of cluster structures in a complex network is introduced to resolve the problem on the similarity measure between the state division and partition criteria. The failure status and characteristics are reflected by network structure, then the fault diagnosis network model is established, and fault diagnosis of the transmission line is transformed into sub-networks to detect problems. For various fault signatures of the same fault, multi-sensor can collect different characteristic value in multi-level and multi-field. High sensitivity state information can be selected to analyze the fault diagnosis better. The experimental results show that the proposed algorithm can achieve higher diagnosis accuracy and has better fault tolerance.关键词
