Title: Power Disturbance Analytics - Emerging Directions in Power Quality Research
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 in-formation about the conditions of a system and its equipment. As a result, initiatives that explore the "useful" as-pects 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 lo-cate 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. If time allows, other power quality research activities in U of A will also be discussed.
徐文远（Wilsun Xu）, 1989年毕业于加拿大不列颠哥伦比亚大学，获博士学位，1996年9月开始在加拿大阿尔伯塔大学电气与计算机系任教，现为终身教授，主要研究领域为电能质量和分布式发电。2003年2月被聘为教育部“长江学者”特聘教授。因在电力系统谐波分析、仿真和测量上的突出贡献，2005年当选为IEEE Fellow（国际电气电子工程协会院士），同时也是加拿大工程院院士，并担任IEEE多个技术委员会的委员以及期刊IEEE Transactions on Power Delivery和IEEE Power Engineering Letters编辑。
The presenter, Dr. Wilsun Xu, is currently a 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 in-dustry as a professional engineer. 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. He is also a fellow of the Engineering Institute of Canada. Dr. Xu serves frequently as a panelist, seminar speaker in IEEE and others conferences, and as a con-sultant for industry. He is currently a member of several committees of the IEEE Power Engineering Society and other institutions, including serving as the power quality editor for the IEEE Transactions on Power Delivery and IEEE Power Engineering Letters. In 2008, Dr. Xu was awarded the Senior Industrial Research Chair in Power Qual-ity by the Natural Sciences and Engineering Research Council of Canada.
