TITLE

Harmonic Resonance in Power Systems: Assessment & Mitigation

GUEST LECTURER

Dr. Wilsun Xu, University of Alberta, Canada

TIME

10:00 - 12:00

ABSTRACT

Harmonic resonance has become a common concern for power system planning and operation due to widespread adoption of power-electronic based devices at various voltage levels. This presentation will share research results on harmonic resonance assessment and mitigation from the perspective of power systems. One result shows that harmonic resonance is closely related to the eigenvalues of the network admittance matrix. Based this finding, methods to identify resonance locations and contributing components are developed. An index to quantify the severity of resonance is established. Another result introduces the concept and topology of resonance-free capacitor. Industry has found that it is an effective way to deal with shunt capacitor caused harmonic resonance problems. Finally, the presenter will share briefly his recent research activities related to power disturbance analytics, a field that makes use of power disturbances for stability monitoring of power system and condition monitoring of power equipment.     

ABOUT THE LECTURER

The presenter, Dr. Wilsun Xu, obtained B.Eng. from China in 1982, M.Sc. and Ph.D. from Canada in 1985 and 1989 respectively.  He worked in Canadian power industry for 7 years before joined the University of Alberta in 1996.  He is specialized in power quality which essentially deals with the assessment, measurement and mitigation of various power disturbances. Dr. Xu was elected to IEEE Fellow in 2005 and a Fellow of Engineering Institute of Canada in 2006 for outstanding contributions to power quality research. His research work has also resulted in several patents with three of them commercialized. 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. He is currently the Editor-in-Chief of the IEEE Transactions on Power Delivery and a board member of the Alberta Power Industry Consortium, Alberta, Canada.

THE GUEST LECTURE WILL TAKE PLACE AT Pon 101 in room 23 AND ALL ARE WELCOME.
