Wensheng Song received the B.S. degree in electronic and information engineering and the Ph.D. degree in electrical engineering from Southwest Jiaotong University, Chengdu, China, in 2006 and 2011, respectively. From September 2009 to September 2010, he was a Visiting Scholar with University of California at Irvine, USA. From July 2015 to December 2015, he was a Visiting Scholar with University of Alberta, Canada. He is currently a Full Professor with the School of Integrated Circuit Science and Engineering, Southwest Jiaotong University. Dr.Song is IEEE senior member, Director of Youth Profession Committee, in China Power Supply Society. In addition, He is the Chair of Technical Program Committee in IPEMC2024-ECCE-Asia. His current research interests include power electronics, motor drives, health monitoring, and reliability of railway traction drive systems. He has published more than 50 IEEE journal papers, hold more than 20 China patents.

Recently, digital twin technology is an interesting and hot topic for high-end equipment manufacturing and maintenance. For railway transportation, electric traction drives system is the heart of high-speed EMUs or locomotives, which is consist of single-phase AC-DC PWM rectifiers, three-phase DC-AC inverters, and motor drive system. Its service status monitoring and safety are the focus of attention in the field of rail transit. Thus, this topic will focus on the application of digital twin technology in electric traction system. we will discuss how to develop the digital twin model of the electric traction drives system, how to use this model to monitor the health status of the key comments, and to realize the parameter identification and fault diagnosis.
