The calculation module pre-processes the collected data, removes noise, and uses a moving average filter to smooth the data, thereby eliminating obvious noise points. The calculation module continues to extract the time series characteristics of the data, including the mean, variance, maximum value, minimum value, and peak value of each data. The time series data is converted into frequency domain features through the Fourier transform method, and the frequency components are extracted to calculate the data. Statistics, including mean, standard deviation, skewness, and kurtosis. The calculation module calls historical data from the storage module and analyzes the threshold values ​​of each data.

It analyzes the correlation between different parameters and identifies the combination conditions that may cause faults. Based on historical fault records, it identifies common fault types such as short circuit, disconnection, overload, etc. For abnormal data, it matches the fault model, selects the features most relevant to the fault type, constructs feature vectors, and generates fault information.

[0053] Finally, the backup power supply 8 supplies power to the DTU body 41, and the DTU wireless terminal in the DTU body 41 controls the backup power supply 8 to adjust the output current through the inverter 6, so as to adjust the data to restore the balance of the circuit, thereby improving the flexibility and stability of the power grid.
