摘要

随着交联聚乙烯电力电缆使用寿命的延长，如何确定资产更换时间，避免因老化造成的事故已成为一个重大问题。本文证明了双聚类补全(BC)原理可用于恢复矩阵的缺失元素，并首次应用于电缆寿命评估。选取负载伸长率、永久伸长率、断裂伸长率、差示扫描量热峰值温度、击穿试验率、绝缘电阻等6项指标对交联聚乙烯电力电缆的寿命进行评价。仿真结果表明，该算法在精度和鲁棒性方面都优于传统的反向传播算法和回归算法。

A novel life evaluation algorithm of XLPE Power cables based on biclustering

With prolonged operation durations of XLPE power cables, how to determine asset replacement time to avoid the accident caused by aging has become a major issue. In this paper, the biclustering completion (BC) principle is proved for restoring missing elements of a matrix and is firstly applied in the cable life evaluation. Six indicators such as load elongation, permanent elongation, breaking elongation, differential scanning calorimetry peak temperature, breakdown test rate and insulation resistance are selected to the life evaluation of XLPE power cables. The simulation results show that the biclustering algorithm is better than the traditional backpropagation algorithm and regression algorithm in accuracy and robustness.
