     Sherif O. Faried  B.Sc., M.Sc., Ph.D.

    Professor of Electrical and Computer Engineering


    Dr. Faried received the B.Sc. and M.Sc. degrees from Ain Shams University, Cairo, Egypt, in 1979 and 1984, respectively, and the M.Sc. and Ph.D. degrees from the University of Saskatchewan, Saskatoon, SK, Canada, in 1988 and 1993, respectively, all in electrical engineering.

    Dr. Faried's research interest is in the area of power system dynamics,stability, protection and control. His research focuses on investigating the various aspects of the dynamic performance of power systems at the level of a given machine, an area, or for an interconnected region. Designing and evaluating new control technologies to improve power system stability and dynamic performance is another important aspect of the research. Dr. Faried has carried out research on subsynchronous resonance, torsional oscillations of large turbine-generators and the applications of probabilistic methods to power system dynamics. His research has led to new methods for reducing the high torsional torques induced in turbine-generator shafts during clearing and high-speed reclosing of multi-phase system faults. He has also studied and introduced Adaptive Short Time Compensation as a new concept for improving power system stability and reducing turbine-generator shaft torsional torques. Current research projects include design of FACTS (Flexible AC Transmission Systems) controllers for damping power system oscillations, impact of superconducting fault current limiters on the coordination between generator distance phase backup protection and generator capability limits, protection of phase imbalanced hybrid series capacitive compensated transmission lines.

    Professional Activities: Senior member of the Institute of Electrical and Electronic Engineers and a registered professional engineer in the province of Saskatchewan.
