摘要
Abstract
Based on the principle of acoustic imaging,the acoustic signal generated by the partial discharge of power equipment is measured by the microphone array.The acoustic imaging algorithm is used to locate the sound source of partial discharge and achieve the purpose of partial discharge location detection.On the basis of the comparison and analysis of several acoustic imaging algorithms,an improved acoustic imaging algorithm based on the orthogonal matching pursuit deconvolution approach for the mapping of acoustic sources(OMP-DAMAS)is proposed for the partial discharge localization.The experimental verification shows that the OMP-DAMAS acoustic imaging algorithm can not only maintain high precision positioning,but also significantly reduce the calculation time of the algorithm,which is suitable for the partial discharge positioning detection of power equipment.关键词
