基于小波和关联维度特征提取的雾霾天绝缘子泄漏电流分析

Analysis of Insulator Leakage Current under Fog and Haze Based on Wavelet and Correlation Dimension Feature Extraction

随着气候雾霾污染问题加剧,绝缘子在雾霾条件下的工作也出现和传统环境下不同的情况。通过实验模拟绝缘子在雾霾条件下的工作状态,测量绝缘子雾霾天的泄漏电流,提出利用小波分析和关联维度特征值对雾霾天的泄漏电流进行对比分析。同时,给出关联维度分析方法的缺陷以及改进办法。

With the aggravation of fog and haze pollution,the work of insulators in haze condition is different from that in the traditional environment. The working state of insulator under fog and haze condition was simulated,and the leakage current of haze days was measured. The leakage current of haze days was compared and analyzed by using the wavelet analysis and the eigenvalues of the associated dimension. Meanwhile the defects of the correlation dimension analysis method and the improvement method were given.
