What is Machine Learning in Electrical Fault Diagnosis?
Machine Learning in Electrical Fault Diagnosis applies SVM, neural networks, and deep learning to classify faults in power systems using features from transient waveforms and wavelet transforms.
Research employs models like LVQ-NN, PSO-SVM, and convolutional neural networks on PV systems and transmission lines. Over 1,000 papers exist, with top works including Lu et al. (2019, 140 citations) on DA-DCGAN for DC arc faults and Yadav and Dash (2014, 95 citations) on ANN for transmission line protection. Focus areas include real-time detection and predictive maintenance in smart grids.
Why It Matters
ML fault diagnosis enables predictive maintenance in PV systems, reducing outages and fire risks as shown in Wu et al. (2020) review of hotspot effects and DC arcs. In transmission lines, ANN methods by Yadav and Dash (2014) provide instant fault isolation for system stability. Applications in smart grids support IoT integration for fault prediction, per Mahmoud et al. (2021) systematic review.
Key Research Challenges
Imbalanced Fault Data
Rare fault types like series arcs lack sufficient training data, degrading ML model performance. Lu et al. (2019) use DA-DCGAN to generate synthetic samples for DC arc detection in PV systems. Real-world variability in environmental conditions further complicates balanced datasets.
Real-Time Processing
Extracting features from wavelet transforms for transient signals demands low-latency inference. Qu et al. (2019) apply LVQ-NN and PSO-SVM for series arc faults but note computational overheads. Edge deployment in power systems requires optimized models for microsecond responses.
Feature Extraction Complexity
Selecting robust features from I/V curves and waveforms under noise remains challenging. Basnet et al. (2020) analyze PV faults via I/V parameters in winter conditions. Gao and Wai (2020) propose CNN-RGRU but highlight dependency on high-quality preprocessing.
