A Leakage Fault Diagnosis Method for Low-Voltage Distribution Areas Based on Multidimensional Feature Extraction and LightGBM
After photovoltaic (PV) generation is connected to a low-voltage distribution area, the residual current becomes more complex, noisier, and more variable in amplitude, which may cause conventional residual-current protection devices to mis-operate or fail to operate. To address this issue, this paper proposes a leakage...
