摘要
特征信息提取作为电力电子电路故障诊断的重要环节,直接影响到诊断结果的有效性。阐述了目前常用的各种故障诊断提取方法,结合实际应用对各个方法进行了优缺点评价。在此基础上,提出了未来特征提取方法的新思路,即构造能够发挥各自优点,实现功能互补的特征提取方法,为进一步提高故障诊断的准确性提供参考。
Feature information extraction, which directly influences the validity of diagnosis result, is an important link in power electronic circuit fault diagnosis. This paper summarized some methods of fault feature extraction in common use and evaluated the advantages and disad- vantages of each method with the combination of practical application. On the basis of this, this paper proposed a new idea for future feature ex- traction methods, which constructed the feature extraction method to bring each advantage into play and to realize the complementary function, to provide reference for further improving the accuracy of fault diagnosis.
