S&C’s Power Systems Services Seminar:

Power System Voltage Stability

In the last decade there have been a number of incidents of fault induced delayed voltage recovery or voltage collapse that resulted in a significant loss of power system load. The most recent blackout of August 14, 2003 in the Northeastern United States and Canada is a good example of such incident. Furthermore, the increased loading of power system transmission lines and equipment is resulting in operation closer to the stability limits of the system. As a result, there is increasing concern over the secure operation of power systems all over the world.

This 2-day course will provide a comprehensive overview of fundamental concepts on voltage stability, such as the significance of reactive power management and voltage control. Modeling and analysis techniques to identify potential voltage stability problems and solutions during the planning, design, and operation of power systems will also be presented. The course will also cover in detail various technologies available today to prevent voltage instability on power systems, including static var compensators and inverter-based dynamic compensators. Case studies of actual voltage instability problems and equipment solutions will also be presented. The impact of wind generation on system voltage stability, interconnect requirements, reactive power and voltage control equipment solutions will also be covered.

Who Should Attend

Electric Utility transmission and distribution engineers, consultants, and other personnel involved in transmission system planning, design, and operation.

Prabha also served as Adjunct Professor at the University of Toronto since 1979 and at the University of British Columbia since 1994. He is the author of the book Power System Stability and Control (McGraw-Hill, 1994), which is a standard modern reference for the subject. He has performed extensive international consulting related to power system stability and control, and has delivered technical courses for utilities, manufacturers and universities around the world.

Dr. Kundur has a long record of service and leadership in the IEEE. He has chaired numerous committees and working groups of the Power Engineering Society, and was elected a Fellow of the IEEE in 1985. He is the Immediate Past-Chairman of the IEEE Power System Dynamic Performance Committee, and currently the PES Vice-President for Education/Industry Relations. He is the recipient of several IEEE awards, including the Nikola Tesla Award in 1997 and the Charles Concordia Power System Engineering Award in 2005. He has also been active in CIGRE for many years. Dr. Kundur is currently the chairman of the CIGRE Study Committee C4 on “System Technical Performance”. He was the recipient of the CIGRE Technical Committee Award in 1999.

In 2003 he was inducted as a Fellow of the Canadian Academy of Engineering. He has been awarded two honorary degrees: Doctor Honoris Causa by the University Politechnica of Bucharest, Romania in 2003, and Doctor of Engineering, Honoris Causa by the University of Waterloo, Canada in 2004.
