摘　　要：针对电力变压器故障现象、故障机理具有不确定性和模糊性,从而难以客观有效地评估等问题,以110 kV油浸式电力变压器为研究对象,提出了用集成算法构建变压器状态综合评估模型,即利用德尔菲法、层次分析法、灰色理论以及模糊理论等算法的优点和适用性,实现了对变压器状态的综合评估。通过实例分析,并且与模糊综合评判法进行对比分析。Realizing the evaluation of transformer＇s running state accurately and timely is not only the premise of State maintenance but also the requirement of the power grid intelligence reformation. Because transformer＇s fault phenome- na and fault mechanism are uncertain and fuzzy, it is hard to evaluate it objectively and effectively. A 110kV oil im- mersed type transformer was analyzed in this paper, DHGF integrated algorithm was proposed to build a transformer＇ s comprehensive state assessment model. Using the advantages and adaptation of Delphi, analytic hierarchy process, Grey Theory and Fuzzy mathematics to evaluate transformer＇s state. By analyzing an example and comparing with fuzzy comprehensive evaluation, it proves effective and reasonable to use this method that using DHGF can provide theoretical basis for the implementation of condition maintenance.
