| 摘 要： | 变压器运行状态的有效评估是指导电力变压器状态检修以及保证电力系统安全可靠运行的重要手段。在变压器智能组件得到的各类在线监测状态信息量的基础上,引入可拓理论,建立了基于在线监测的变压器状态综合评估模型。采用改进层次分析法与灰色关联分析相结合计算得到综合权重,指出该方法克服了单一方法确定指标权重的局限性;基于物元理论和关联函数理论构建变压器状态综合评估模型,实现对变压器状态定性和定量相结合的状态评估,为变压器的状态检修提供了决策依据。实例分析证明了该评估模型的准确性和有效性。

| Abstract: | Condition assessment of transformers is an important approach to provide guidance for the state overhaul of power transformers and improve the operation reliability of power system.On the basis of the on-line monitoring state information,a new transformer condition assessment model is proposed in the paper.Firstly,the synthesis index weights are figured out by means of improved analytic hierarchy process and gray correlation analysis,which overcomes the defect of a single method to ascertain the index weigh... |
