In this paper, an evaluation method based on polarization and depolarization currents (PDC) multi feature weight for cable insulation ageing state was proposed. Firstly, on the basis of PDC method, several ageing characteristic quantities reflecting insulation state were extracted. Secondly, the ordered binary comparison quantization method and principal component analysis method were used to determine the weight of feature quantity from subjective and objective aspects, and on the basis of DS (Dempster/Shafer) evidence theory, the subjective weight and objective weight were fused effectively to get the fusion weight. Thirdly, on the basis of the fuzzy comprehensive evaluation method, the effective evaluation of cable insulation ageing state was realized by combining with the fusion weight. Finally, the effectiveness of the evaluation method was verified by an example. The results show that the proposed method can evaluate the cable insulation ageing status effectively and accurately, which can provide a new direction for the evaluation of cable insulation ageing status.

本研究提出一种基于PDC法多特征量权重的电缆绝缘老化状态评估方法。首先,基于PDC法测试提取出多个体现绝缘状态的老化特征量。其次,采用有序二元比较量化法与主成分分析法,分别从主观和客观两方面确定特征量的权重,基于DS(Dempster/Shafer)证据理论将主、客观权重进行有效融合获得组合权重。接着,基于模糊综合评估,结合获得的组合权重共同实现电缆绝缘老化状态的有效评估。最后通过实例验证评估方法的有效性。结果表明:所提方法能有效、准确地评估电缆绝缘的老化状态,可为电缆绝缘的老化状态评估提供一种新方向。
