Transcript of Wind Power

Wind Turbine Drivetrain Testing Facility Wind Power Zayna Sheikh HAWT Design Power Statistics HAWT's Design Types VAWT's What is a Watt? Modern Windmill HAWT Less Common Aerodynamics Typical wind turbine look Rotor Blades Large Turbines- 33mph Globally creating as much as 8 nuclear power plants History 3000 B.C. -Egyptian Sailboats Important Points Consistency of speed 1086 - 6000 Watermills Urban Wind Energy VAWT over HAWT Offshore Wind May be the future of wind energy Denmark On and offshore projects How it will Help C.C.- worst air in Massachusetts Cape Wind The Nantucket Sound in Cape Cod In North Charleston Clemson University builds the Wind Power Does wind power seem like a good solution to our energy crisis? General in the USA 25-100 Watts = 1000 Watts = 1 Kilowatt 1000 Kilowatts = 1 Mega watt (kW) (MW) -A mill or machine operated by the wind usually acting on oblique vanes or sails that radiate from a horizontal shaft 2000 B.C. -Windmills in the Middle East 1000 A.D. -Crusaders brought design home 1930's -600,000 windmills -Drag -Lift Airfoil design Blade length VAWT Elevation -Horizontal Axis Wind Turbine Double height =12% increase in wind speed -Vertical Axis Wind Turbine Needs a boost Always aligned with the wind Usually 280 ft tall Always changing direction Mounted horizontally Shaft Generator -Electromagnetism Electronic Control Unit Yaw Mechanism Brakes Stops after 45mph Electrical Equipment Brakes: Pitch Control Passive Stall Control Active Stall Control -The twists in the blades -Electric control makes them unaligned -Pitches blades to create stall An american household uses 10,000 kW per year -A small turbine creates up to 16,000 kW -A Large turbine creates up to 5.2 million kW Enough to power 600 houses Wind Farms Potential to generate up to 10.8 trillion Very cost-efficient Wind output in the USA = 3.6 trillion kW -About 20 billion barrels of oil Minimum wind speed: Small turbine -9mph Large turbine -13mph Speed of wind Betz Limit Albert Betz 1919 Double the speed = Eight times more power Only 59% Impossible to harness all 100% Introduction to Wind One World Polluted Unclean Out of resources Without Green Energy But not yet possible UK Wind No Windmills Cabinet Office Strategy Unit Wind is cheaper Department of Trade and Industry Nuclear is cheaper 1200 - Windmills along Eastern England Less noise Less maintenance No need to change direction More aesthetically pleasing Looking at offshore for the future 11 potential locations for wind farms -Now through 2020 -2,000 turbines -6,000 MW total 1st offshore project- 1991 2nd largest manufacturer in Spaced far apart in rural areas One of the largest wind farms in the world -Off the coast of Ireland -200 turbines -520 MW -Almost 600 million $ Many countries have it : China, the UK, Denmark, Belgium etc. The USA does not Only in the process Cape Wind Ideal spot: Strong wind resource
Shallow depth
Low ocean storm waves 130 turbines
420 MW Will cut 734,000 tons of gas emissions 113 million gallons of oil per year 1,000 jobs in construction 150 permanent jobs Boosting local economy Navigation Testing Facility and US Department of Energy
-Goal to power 20% of the US through wind Work started in 2010 and through 2012 -Through 2013 exterior walls and plan done -Foundation was set and the design complete Wind power could be the answer Utilize potential areas Any Questions or Comments? -Usage decreased in the USA 1970 A.D. -Demand picked back up Why use Wind Clean and renewable Does not release CO2 Ups Works Cited Archer, Cristina.
