基于FRCMDE与IBOA-LSSVM的变压器故障声纹诊断方法
Fault Voiceprint Diagnosis Method for Transformers Based on FRCMDE and IBOA-LSSVM
摘要
Abstract
In order to improve the sensitivity of multiscale dispersion entropy to signal evolution and raise the accuracy of transformer fault voiceprint diagnosis,the fractional-refined composite multiscale dispersion entropy(FRCMDE)was ap-plied to transformer voiceprint feature extraction.Firstly,the parameters of FRCMDE are determined and the FRCMDE en-tropy features of transformer sound signals in different states were extracted.Secondly,the Improved Butterfly Optimization Algorithm(IBOA)was introduced to optimize the parameters of the Least Square Support Vector Machine(LSSVM)to con-struct an IBOA-LSSVM model,which was used to classify data features for transformer fault voiceprint diagnosis.Finally,to verify the effectiveness of this method,its result was compared with that of other classical methods.The research results show that the proposed FRCMDE-IBOA-LSSVM model can effectively distinguish transformer's sound signals in 8 states,and the diagnosis accuracy reaches 99.69%,which is higher than other methods.This method may provide a reference for transformer non-stop monitoring and fault voiceprint diagnosis.关键词
