Research on Key Technologies for Environmental Noise Identification of Distribution Transformer
A noise recognition method based on wavelet transform,Support Vector Machine(SVM),and noise feature library is proposed to address the complex and variable environmental noise of distribution transformers.This method first uses wavelet transform to preprocess the noise signal,then uses SVM to extract noise features and classify them,and finally combines the noise feature library to comprehensively determine the type of noise.The experimental results show that the noise recognition accuracy,recall rate,F1 value and other indicators of this method are superior to traditional methods,providing a new idea for precise noise reduction of distribution transformers.
