Dr. Babak Fahimi and the Renewable Energy and Vehicular Technology lab would like to present Professor Frede Blaabjerg of Aalborg University, Denmark, as one of our Distinguished Speakers on Energy for this semester. Group question and answers are welcome after his talk. A reception and informal one-on-one time follows.

Wind Power – A technology enabled by power electronics
The steady growth of the installed wind power, reached 200 GW capacity in 2010, together with the up-scaling of the single wind turbine power capability - 8 MW’s are announced by manufacturers, has pushed the research and development of power converters towards full scale power conversion, lower cost pr kW, higher power density and need for a higher reliability. Substantial efforts are carried out to comply with the more stringent grid codes, especially grid faults ride-through and reactive power injection, which challenges the power converter topologies, because the need for crowbar protection and/or power converter over-rating has been seen in the past in the case of a doubly-fed induction generator. The presentation will first give a technology overview. Next power converter technologies are reviewed with focus on single/multi-cell power converter topologies. Further - case studies on the Low Voltage Ride Through demand to power converter are presented including a discussion on reliability. Finally, discussions about topologies for wind farms will be provided.
