信息融合技术在电力变压器故障诊断中的应用

Application of Information Fusion in Synthetic Insulation Fault Diagnose of Power Transformer

根据变压器运行原理和结构特点,将信息融合思想引入到变压器的故障诊断中,建立基于信息融合技术的故障诊断模式,即通过曲面拟合算法和证据推理技术从不同侧面,充分利用各种特征信息对变压器的故障进行诊断,来有效地提高确诊率。

Based on the fault principle of power transformer, the ideas of information fusion are introduced in this paper, the synthetic insulation fault diagnostic model of power transformers utilizing information fusion is proposed. That is, the paper discussed using the camber fitting methed and Dernpster-Shafer (D- S) evidence reasoning technique, it show clearly that the information fusion method upgrades diagnose precision fairly conspicuously.
