在综合考虑预防性试验结果、电缆工作环境、运行数据、检修记录情况的基础上，基于电力电缆线监测数据和历史数据应用层次分析法，构建了反映电缆运行状态重要特征的评估指标体系；采用相对劣化度表征指标恶化程度，使用混合方法建立定性指标和定量指标的隶属函数，利用模糊综合评判法建立电力电缆运行状态评估模型，通过对项目层、子项目层多状态因素进行评估，综合得到电力电缆的实时运行状态。某实例隧道内220 kV电缆的运行分析表明了该评估模型的合理性和有效性。

With some considered data, such as preventive experiments result, working surroundings, operation records, maintenance records, and so on, by using the method of analytic hierarchy process, an improved fuzzy synthetic evalua-tion assessment model for cables was proposed, the relative interiority indicator was adopted, and different methods were used to determine the membership functions for qualitative indices and the quantitative indices.Through assessing the layer and sub-layer factors, the comprehensive operating condition of cables can be achieved.Based on the actual monitor data for a 220 kV cable in power tunnel, analysis result shows the proposed assessment model was correct and effective.
