Research on multi-physics coupling calculation and fast computation method of power equipment

The application of artificial intelligence and digital twin technology in intelligent decision-making and control of power grid has attracted much attention, which raises the demand for panoramic state perception and dynamic and flexible regulation of power equipment. Transformers are widely used in power grid, but the transformer equipment is prone to high local temperature, which seriously affects the safe and stable operation of power system. Therefore, in order to ensure safe and stable operation, it is necessary to analyze the temperature distribution of the transformer. This paper firstly obtains the temperature distribution under different working conditions through the multi-physical field coupling calculation of the transformer, and then obtains sample data on this basis, and then builds a proxy model to realize the rapid calculation results of the temperature field of the transformer winding.
