摘要
基于数学形态学基本原理,构造了一种多结构元素并行复合形态滤波器,并应用于MOA泄漏电流的提取,首次提出了基于形态谱的MOA早期故障诊断方法。MATLAB仿真和实测数据的分析表明,该滤波方法可以准确提取泄漏电流信号,大幅度提高信噪比。形态谱为MOA早期故障诊断提供了一种新思路。
In order to extract the leakage current, a parallel-composed morphological filter with multiple structuring elements based on the principle of mathematical morphology is designed. Also, pattern spectrum is first used in the early fault diagnosis for MOA. MATLAB simulation and experimental data analysis demonstrated that the filtering algorithm can gain the real leakage current precisely and enhance the SNR （signal-to-noise ratio） greatly. The pattern spectrum gives a new idea for the early fault diagnosis of MOA.
