Simulation and Experimental Validation of the Core Temperature Distribution of a Three-Phase Transformer
发布日期 2014
This paper presents an application of COMSOL Multiphysics® software in the study of the temperature distribution of a 5kVA three-phase air-cooled transformer. A 3D, steady state model was utilized on the simulations. The interface with the surrounding air was modeled by Newton's Law of Cooling, discarding the need of solving the external air flow.
The simulation agreed with the experimental results with a margin of 2.3 degrees Celsius with a remarkable short amount of simulation time. Given the fact that the time constants associated with the heat flow are greater than the simulation time, real-time control strategies could be implemented in the future.
