Research on Low Voltage Power Supply Cable Fault Diagnosis Based on Multi-Source Information Fusion and One Dimensional Convolutional Neural Network
摘要
Abstract
[Objective]To address issues in traditional low-voltage power cable fault diagnosis,such as reliance on a single signal,insufficient feature extraction,and weak anti-interference capability,an intelligent diagnostic strategy is proposed that can achieve high robustness and high-precision identification under complex operating conditions.[Methods]An intelligent diagnostic method integrating variational mode decomposition-Hilbert transform(VMD-HT)and multi-source one-dimensional convolutional neural network(MS-1DCNN)was proposed.A time-frequency analysis framework was constructed using VMD and HT to adaptively decompose signals of different modes and quantify feature parameters.Meanwhile,the MS-1DCNN structure was designed to achieve unified modeling and diagnosis of multiple types of cable faults.[Results]The experimental results demonstrated that the proposed MS-1DCNN diagnostic model outperformed conventional methods in terms of fault feature separability,classification accuracy,and stability under complex noise conditions.Superior robustness to hyperparameter variations was also verified.[Conclusion]The proposed MS-1DCNN model significantly enhances the reliability of fault identification in low-voltage cables,making it suitable for online monitoring and early warning scenarios in actual power grids.It provides a scalable technical solution for ensuring the operational safety of low-voltage distribution systems.关键词
