摘要
Abstract
Addressing the issues of difficulty and low accuracy in identifying DC arc faults in photovoltaic systems,this paper proposes a detection method based on deep learning.The current signal undergoes wavelet denoising and an improved adaptive noise complete empirical mode decomposition process.Time-domain features and entropy features are combined to construct feature vectors,followed by the introduc-tion of the CNN-BiGRU-Attention model to achieve the identification of arc faults.Experimental results show that the model achieves an accuracy rate of 98.57%in identifying arc faults,effectively enhancing the protection capability of photovoltaic systems against DC arcs.关键词
