Surrogate Model Based on POD-Kriging for Fast Analysis of Electrical Devices

The Finite Element (FE) analysis is widely employed to analyze electrical devices due to its remarkable accuracy. However, it can prove to be time-consuming, especially for multi-physics simulations. To overcome this challenge, a combination of proper orthogonal decomposition (POD) and Kriging interpolation is utilized to create a surrogate model, which can provide quick approximations of FE solutions. In this study, the POD-Kriging approach is implemented to examine the steady current-heat conduction transient problem in a dry-type transformer.
