Presentation:Presentation Summary:

Tour NASA Glenn Research Center Variable Frequency Power System.


The existing NASA GRC Variable Frequency Power System  provides and absorbs  pure three phase power from 10 to 120 HZ  at voltages from 550VAC up to 7200 VAC to test aircraft engine components and turbines up to 15,000hp  (20MW) in size. A presentation the system functionality and how it is controlled will be provided along with a guided tour.

Tour Guide: Don Brown, PE
