Abstract:To enable rapid and precise detection of abnormal discharge hidden danger in main transformer after trip and energization,an intelligent detection and early-warning system based on multi-source data fusion and deep learning is proposed. The deployment of UHF sensors,acoustic sensors,and temperature sensors facilitates real-time acquisition of acoustic,electromagnetic,and thermal signals in main transformer after trip and energization. The wavelet transform is used to extract the time-domain and frequency-domain features,and a hybrid deep learning model is constructed to achieve the recognition and classification of anomalous discharge signals. Test results confirm that the system can achieve intelligent detection and early-warning of abnormal discharge hidden danger in main transformer after trip and energization,enhancing the safety and reliability of power grid operation.
