Physics-Structured POD–Neural Networks for Reduced-Order Modeling of the Three-Dimensional Temperature Field in HVDC Cables Across Operating Conditions
The temperature field of a high-voltage direct-current (HVDC) cable governs its current rating and insulation lifetime and must therefore be predicted accurately across diverse operating conditions. Finite-element (FE) simulation is accurate but too costly for repeated evaluation, whereas data-driven reduced-order mode...
