Faculty Host: Professor Fransisco De Leon
This seminar deals with the author’s experiences in modelling complex winding arrangements encountered in large power transformers for the simulation of internal (very fast transient) voltage distribution. Models are based on RLCG lumped frequency-dependent parameters taking into account different combinations of windings and including the presence of the tap changer. Measurements were carried out and compared with simulation results.
Xose M. López-Fernández received master's and PhD degrees in electrical engineering (with first class honours) from Vigo University, Vigo, Spain, in 1992 and 1997, respectively.
He is currently a professor in the Department of Electrical Engineering, University of Vigo, and a Visiting Professor at the University of Artois, Béthune, France. He is interested in the design and heating aspects of electrical machines.
Professor Lopez-Fernandez is an IEEE and CIGRE member. He was chairman of the Organising Committee of International Symposiums on Electromagnetic Fields in Electrical Engineering held in Baiona-Spain in 2005 (ISEF2005), and a member of the Steering Committee of ISEF. He was a co-guest editor of issues of the Emerald journal COMPEL and a co-author of the book Electromagnetic Fields in Mechatronics, Electrical and Electronic Engineering, vol. 27 (IOS Press, 2006) ISBN 1-58603-627-0. He is publisher and co-editor of the e-monograph Transformers in Practice, ISBN: 978-84-609-9615-9.
Professor Lopez-Fernandez is the general chairman of the Advanced Research Workshop on Transformers, which was successfully held in 2004-Vigo-Spain and 2007-Baiona-Spain. Dr. Lopez-Fernandez received the Alfons Hoffmann’s Medal from the Polish Power Engineering Society in 2004. He acts as a consultant for Red Eléctrica de España (REE), Gas Natural-Unión Fenosa utility, EFACEC Energía, and Advisory Board Member of Centre of Excellence of the Electrotechnical Institute of Warsaw, Poland.
