[0066] Example
[0067] Such as Figure 1 to Figure 10(b) As shown, the low-voltage power distribution system series fault arc identification method based on full-phase deep learning includes:
[0068] Under the low-voltage AC system, collect current signals for different loads in the low-voltage circuit;
[0069] Perform full-phase discrete Fourier transform on the collected current signal, extract the full-phase spectrum feature quantity of the load, and construct a full-phase spectrum feature vector;
[0070] Use the built full-phase spectrum feature vector to construct a deep learning neural network model based on Logistic regression, and conduct deep learning training on full-phase spectrum feature quantities under different loads and different operating conditions until the model converges;
