基于多源信息的变压器故障诊断与状态评价方法研究

Multisource Information-based Fault Diagnosis and State Evaluation of Transformers

针对变压器结构复杂、故障种类多、状态量多的特点,建立了基于多源信息的变压器故障诊断与状态评价模型,按照故障类型故障指数评估→部件状态评估→设备状态评估的层次逐级进行状态评价,为变压器的综合诊断提供了有效的判断方法。同时,针对变压器的故障诊断,提出了一种多维度的故障诊断方法,通过故障指数量化评价变压器故障的严重程度,对其相对劣化程度和故障程度提供了科学合理的评估方法。

In view of complex structure,diversified fault types,and multiple states of transformers,this paper establishes a transformer fault diagnosis and state evaluation model based on multisource information.The state evaluation is carried out step by step according to the hierarchy of fault index evaluation,component state evaluation,and equipment state evaluation,providing an effective judgment method for comprehensive diagnosis of transformers.Moreover,for transformer fault diagnosis,this paper proposes a multi-dimensional fault diagnosis method that quantifies the severity of transformer faults through fault indices,providing a scientific and rational evaluation method for their relative deterioration and fault severity.
