Overview

Randomized trial demonstrates improved temperature calculations in UHV transformers, suggesting a better efficiency method.

Key Points

  • This research aims to develop a rapid and accurate model for calculating temperature fields in ultra-high-voltage transformers under extreme conditions.
  • Established a full-order model for electromagnetic-fluid-thermal coupling.
  • Developed a reduced-order model using proper orthogonal decomposition and Kriging for efficiency.
  • Analyzed temperature field calculations under various operating conditions.
  • Maximum relative error of the ROM was 2.92%.
  • Single-step calculation time reduced to 1.02 seconds.
  • Computational efficiency increased by 8894 times compared to the full-order model.
