Transformer fault detection system applying artificial intelligence to smart power grid

The invention relates to a transformer fault detection system applying artificial intelligence to a smart power grid, which comprises a preprocessing server, a data analysis server, a graph model construction server and an anomaly detection server, wherein the servers are in communication connection. The preprocessing server preprocesses the abnormal voltage and current data and inputs the abnormal voltage and current data into an abnormal frequency model to output an abnormal characteristic frequency. The data analysis server obtains voltage and current frequency domain data based on the voltage and current data so as to construct a current and voltage spectrogram. The graph model construction server establishes a voltage and current sequence graph model by taking each abnormal characteristic frequency of the current and voltage spectrogram of each transformer in each period as a vertex and taking a difference value of amplitudes of the abnormal characteristic frequencies as a weight coefficient. The anomaly detection server carries out graph aggregation and graph decomposition on all the voltage and current sequence graph models to generate an anomaly detection graph model so as to carry out real-time monitoring and anomaly detection on each transformer.
