Sheffield Delegates Visited EE College

Edited byzx Date:2016-10-17 16:04

Prof Z.Q.Zhu and his collegue Prof David Stone from the Univeristy of Sheffield, UK visited EE College last Friday on Oct 14, 2016.

Prof Z.Q.Zhu and Prof David Stone visited EE labs on the morning of Oct 14, 2016.

They first had a tour to Lab of Microgrid Experimental Platform that was attached to Zhejiang Provincial Key Laboratory of Electrical Equipments & Systems on Marine Renewable Energy, labs of Electrical Machines, Drives and Renewable Energies, and labs of Power Electronics. The two professors highly valued the cutting-edge research conducted by the College after they went deeply into EE’s research projects in areas of Island Renewable Energy Generation, DC Micro-grid Technology, Energy Storage System, Super UPS System, New Power Electronic Devices, and Wireless Electric Vehicle Charging Technology.

Later that afternoon, the two professors shared their research experience with EE students and faculties. Prof Stone started the presentation with an introduction to Power Electronics and Drives Control Research at the University of Sheffield for various applications from deep sea removed operated vehicles to aerospace applications. In his second presentation”Energy management and battery health monitoring in stationary and vehicle applications”, he stressed that increasingly energy management was playing a crucial role in both stationary and vehicle applications with the rapidly increasing uptake of EV’s and grid connected energy storage. In some ways the requirements for energy management and battery health monitoring were identical in both applications, and in other ways, there were significant differences. He further discussed new and existing approaches to energy management and battery health monitoring in these applications, highlighting opportunities for innovation and simplification.

Prof Zhu then with his talk-Novel High Frequency Signal Injection Based Sensorless Control of PMSMs-brought forward various high frequency signal injection based sensorless control techniques for permanent magnet synchronous machines and then introduced a recently developed novel sensorless method based on zero sequence voltage using either pulsating or rotating high frequency injection. The new method and features were then described in details and compared with those of conventional methods.
