This invention relates to the field of power equipment condition monitoring and intelligent diagnosis technology, specifically to a transformer fault location method and system based on a palladium thin-film hydrogen sensor array. The system deploys a palladium thin-film resistive hydrogen sensor array at multiple key locations in the transformer tank to collect real-time dynamic changes in hydrogen concentration in the oil. A virtual transformer fault dataset generated from a digital twin model of the transformer's operating state is used for training using artificial intelligence algorithms. The trained model can intelligently analyze and match features from sensor signals collected during actual operation, thereby achieving rapid identification and spatial location of internal transformer faults. This invention, by integrating the high sensitivity of palladium thin-film resistive sensors, the simulation capabilities of a digital twin system, and the data-driven characteristics of artificial intelligence algorithms, achieves early warning, fuzzy location, and intelligent diagnosis of transformer faults, offering advantages such as fast response, high accuracy, and strong scalability.

The application relates to the technical field of bridge monitoring, in particular to a windmill-bridge coupling response rapid prediction method for operation traffic flow, which comprises the following steps: step 1: performing traffic flow identification and bridge deck space-time distribution reconstruction processing on collected camera data and ETC data to obtain a bridge deck traffic flow load state sequence; and step 2: performing batch time domain solving processing on the unified coupling equation of the combination of different wind fields, traffic flows, vehicles, road surfaces and wind-induced working conditions to obtain a data sample library. The application solves the problem that the existing high-fidelity time domain dynamics method cannot meet the real-time prediction requirement in the operation stage due to high parameter dimension, large working condition combination quantity and long time consumption of single solving.
