M. Reeves Deputy Project Director Southern California Edison Company Participants: Location: Background: Concept Advantages: Current Status as of April 1, 1979 The Windfree wind turbine uses large rotating barrels instead of blades to intercept energy in the wind and cause rotation of a main power shaft. The machine makes use of the 'magnus effect", which has been adapted to a wind turbine developed by Windfree Inc. under contract with SCE. It requires an electrical system capable of constant frequency under variable RPM conditions. The prototype 100 foot wind turbine would be rated at 600 kw under 40 mph wind conditions. Studies and test data have shown that a Magnus effect wind turbine, although less efficient than conventional propeller types, should have lower first and O&M costs and should have higher capacity factors (would keep operating under higher wind velocity conditions). A joint Windfree/SCE proposal has been submitted to the Solar Energy Research Institute (SERI) for the construction and testing of a 55' magnus effect wind turbine at Edison's wind test site. It is expected that an award will be made by SERI in June 1979. |
