Abstract
A number of key problems in the modeling and application of engineering electromagnetic and thermal fields, involving the advanced material property modeling under complex working conditions, the efficient analysis method and simulation software, and the rigorous examination of the effectiveness and usefulness of large-scale modeling and simulation, are briefly outlined. Based on the industrial background in large power transformers, considering the rapid development of modern transmission and transformation technology and equipment, the major and very challenging research projects, mainly concerned with the modeling and prediction of transformer core loss and stray-field loss, and the multi-physics simulation requirements, for addressing the heating and cooling issues, are highlighted. This chapter provides a short overview of the evolution of modeling and simulation worldwide and stresses that today the simulation of the electromagnetic and thermal fields can be performed with considerable accuracy, even though there are still some important studies that need to continue. Finally, the overall composition of this book is introduced.
