为提高XLPE电缆绝缘诊断精度，结合电缆绝缘在线监测技术研究现状，提出一种以模糊理论为基础，将模糊层次分析法应用于模糊综合评估的XLPE电缆绝缘诊断方法，建立了相应的绝缘综合评估模型。该模型采用模糊层次分析法代替层次分析法对绝缘参数进行权重分配，改进了层次分析法中存在的判断矩阵一致性问题，同时在模糊综合评估过程中引入相对劣化度概念，利用模糊分布建立绝缘参数相对劣化度的隶属函数，从而使模糊评判矩阵更贴近XLPE电缆绝缘的实际老化情况。算例分析表明，基于模糊理论的绝缘综合评估模型用于XLPE电缆的绝缘状态评估是有效、可行的。
To improve the insulation diagnosis accuracy of XLPE cable, an insulation diagnosis method based on fuzzy theory was proposed in combination with on-line monitoring technology research status, in which fuzzy analytic hierarchy process(FAHP) was applied to the fuzzy comprehensive assessing, and the corresponding insulation comprehensive assessing model was established. The model used FAHP to re-place analytic hierarchy process(AHP), improving the judgment consistent problem in AHP. Meanwhile the concept of relative deterioration degree was introduced in the fuzzy comprehensive assessing process, and a membership function of relative deterioration degree of insulation parameter was built using fuzzy distribution, making the fuzzy assessing matrix be closer to the actual aging condition of cable insulation. The example analysis shows that the insulation comprehensive assessing model can effectively and reason-ably assess the insulation condition of XLPE cable.
