Problem StatementThis is a continuation project. The ongoing projectinvolves the design of a wind turbine energy conversionsystem that can be integrated to electrical power grid in theCoover hall power lab. It also includes a display system toindicate the output power from the wind turbine. Thegenerator is rated around 400W. The wind turbine will beinstalled on the roof of the Coover Hall. All the protection andcontrol aspects of the conversion system become part of thedesign. The extension of the project includes the designrequirements to supply stand alone load in conjunction withthe grid supply. At low wind speeds the system is supplementedby the grid source.
