嘉宾介绍：

 Dr. Wilsun Xu, is currently a research chair professor at the University of Alberta, Canada. He obtained B.Eng. from Xian Jiaotong University in 1982, M.Sc. from the University of Saskatchewan, Canada, in 1985, and Ph.D. from the University of British Columbia, Canada, in 1989. From 1989 to 1996, he worked in Canadian power industry. He joined the University of Alberta as a faculty in 1996.

Dr. Xu is an expert in the field of power quality. He was elected to IEEE Fellow in 2005 for contributions to the analysis, simulation and measurement of power system harmonics. Since 2008, he has been holding the position of Senior Industrial Research Chair in Power Quality awarded by the Natural Sciences and Engineering Research Council of Canada. Dr. Xu serves frequently as a panelist, seminar speaker in IEEE and other conferences, and as a consultant for industry. He is currently the Editor-in-Chief for the IEEE Transactions on Power Delivery.

 

主要内容：

Power quality is a field that deals with all sorts of power disturbances. Past power quality research and development activities have been focused on the disturbances’ “harmful” aspects. With the wide spread use of power quality monitoring tools, more and more users and developers start to realize that power disturbances can carry valuable information about the conditions of a system and its equipment. As a result, initiatives that explore the “useful” aspects of power disturbances have emerged. For example, short-circuit caused voltage sag disturbances have been exploited for fault location purposes, characteristics of capacitor-switching transients are used to determine and locate which feeder capacitors are operating normally, the harmonic signatures of home appliances are found useful for tracking the operating status of home appliances, and there are also proposals to use PQ data to detect electricity theft and anticipate the occurrence of feeder faults. Such information-oriented use of power disturbance data and monitoring techniques could emerge as an important field of the future smart grid. This talk will present some of the developments in this emerging field. In the second part of this presentation, the speakers will discuss some of the research projects going on at the University of Alberta.
