| Talk Title: | Operation of a Virtual Air Gap Variable Reactor |
| Slides: | 3-1.ppt |
| Abstract: | The basic operation of a Virtual Air Gap Variable Reactor (VAG-VR) will be presented. Variable Reactors have many applications in the power industry. Their use allows control of line power flow, as well as damping of power oscillations and subsynchronous resonances. A variable reactor is most commonly implemented as a thyristor controlled reactor (TCR) by switching in and out a constant reactance to achieve an averaged variable reactance. By using a virtual air gap, implementation of a continuously variable reactance is possible without introducing the harmonics created by the thyristor switching. A high speed of response is achieved by using a power electronics solution to drive the DC control windings. A full bridge dc-dc converter is used to provide the full range of negative and positive voltage required. |

| Author Bio: | Dale Dolan is currently a PhD. Candidate with the Department of Electrical and Computer Engineering at the University of Toronto, where he received BASc. and MASc. degrees in electrical engineering. His current research involves electromagnetics and power electronic applications for distributed generation. His Master’s research involved wind power generation and constructing a wind turbine emulator capable of dynamic power emulation to aid in control system design. Throughout his graduate program he has published a number of journal and conference articles and has presented work at several international conferences. He is also the chair on the board of directors of Windy Hills Caledon Renewable Energy and is a director on the OSEA (Ontario Sustainable Energy Association) Board. Dale’s educational background also includes an Honours BSc. in Zoology and Environmental Science and Bachelors of Education from the University of Western Ontario in 1995 and 1997 respectively. |
