What Makes Wind:

What Makes Wind Department of Electrical and Electronics E ngineering,AITAM,Tekkali

Slide3:

SOURCES OF WIND Wind is air in motion. Is the result of the conversion of the potential energy of the atmosphere into kinetic energy due to pressure differential. Most prominent feature of climatology in INDIA is the monsoon circulation. Kinetic energy of the wind is about 0.7*10^21 joules Sites having wind power density greater than 200 W/m 2 at 50 m height Department of Electrical and Electronics E ngineering,AITAM,Tekkali

History of Wind Energy:

5000 BC Sailboats used on the Nile indicate the power of wind 500-900 AD First windmills developed in Persia 1300 AD First horizontal-axis windmills in Europe 1850s Daniel Halladay and John Burnham build Halladay Windmill; start US Wind Engine Company Late 1880s Thomas O. Perry conducted 5,000 wind experiments; starts Aermotor Co mpany 1888 Charles F. Brush used windmill to generate electricity in Cleveland, OH Early 1900s Windmills in CA pumped saltwater to evaporate ponds 1941 In VT, Grandpa’s Knob turbine supplies power to town during WWII 1979 First wind turbine rated over 1 MW began operating 1985 CA wind capacity exceeded 1,000 MW 1993 US WindPower developed first commercial variable-speed wind turbine 2004 Electricity from wind generation costs 3 to 4.5 cents per kWh 2011 Wind power provided over 12% of renewable energy used in US History of Wind Energy Department of Electrical and Electronics E ngineering,AITAM,Tekkali

Why Wind Energy?:

Why Wind Energy? Clean, zero emissions - NO x , SO 2 , CO, CO 2 - Air quality, water quality - Climate change Reduce fossil fuel dependence - Energy independence - Domestic energy—national security Renewable - No fuel-price volatility Department of Electrical and Electronics E ngineering,AITAM,Tekkali

Modern Wind Turbines:

Modern Wind Turbines Turbines can be categorized into two classes based on the orientation of the rotor. Department of Electrical and Electronics E ngineering,AITAM,Tekkali

Vertical-Axis Turbines:

Vertical-Axis Turbines Advantages Omni-directional - accepts wind from any direction Components can be mounted at ground level - ease of service - lighter weight towers Can theoretically use less materials to capture the same amount of wind Disadvantages Rotors generally near ground where wind is poorer Centrifugal force stresses blades Poor self-starting capabilities Requires support at top of turbine rotor Requires entire rotor to be removed to replace bearings Overall poor performance and reliability Department of Electrical and Electronics E ngineering,AITAM,Tekkali

Horizontal-Axis Wind Turbines:

Horizontal-Axis Wind Turbines Small (<10 kW ) Homes Farms Remote Applications (e.g., water pumping, Telecom sites, ice making) Large (250 kW-2+ MW) Central Station Wind Farms Distributed Power Schools Intermediate(10-250 kW) Village Power Hybrid Systems Distributed Power Department of Electrical and Electronics E ngineering,AITAM,Tekkali

Large Wind Turbines:

Large Wind Turbines Common Utility-Scale Turbines 328’ base to blade Each blade is 112’ 200 tons total Foundation 20’ deep Rated at 1.5-2 megawatts Supply about 500 homes Department of Electrical and Electronics E ngineering,AITAM,Tekkali

Need of the Hour:

Need of the Hour 1 National Plan A nationwide wind monitoring campaign is to be started at the earliest to have clear picture of wind resource potential of India. Other alternative is to seek advanced methods of assessment by International Agencies for drawing wind atlas of the country Department of Electrical and Electronics E ngineering,AITAM,Tekkali

Need of the Hour:

Need of the Hour Off-Shore Higher in Indian context and needs to be quantified with advanced techniques at Bay of Bengal Arabian sea around Andamans and Nicobar Ilands , and Lakshadeep etc. for wind atlas of the off-shore areas WMS of 50 metre height and above in Himalayan region J&K Himachal Pradesh Laddak Thar Desert and Aravalis in particular & other inland areas in general Department of Electrical and Electronics E ngineering,AITAM,Tekkali

Need of the Hour:

Need of the Hour 2 Off-Shore It needs to be quantified the wind energy potential with advanced techniques at several place around the shore line 3 National Policy Efforts at national level for indigenous development of commercial wind turbines is to be initiated . Department of Electrical and Electronics E ngineering,AITAM,Tekkali

Need of the Hour:

Need of the Hour 4 Massive Efforts Training the man power for inland and off-shore wind farms, use of latest software and efforts for developing Indian version of wind analysis, simulation and modeling software and wind farm design software 5 Education M.Tech level course on Wind Energy can be started in few Institutes Department of Electrical and Electronics E ngineering,AITAM,Tekkali

Need of the Hour:

Need of the Hour 6 Re-Powering Replacing older, less efficient wind turbines with a smaller number of more powerful recent models 7 Targets for Renewable Energy To develop the necessary regulatory frameworks to expand renewables, including financial frameworks , grid access regulation, planning and administrative procedures. Department of Electrical and Electronics E ngineering,AITAM,Tekkali

Need of the Hour:

Need of the Hour 8 Specific Policy Mechanism The market for generated power needs to be clearly defined in national laws , including stable long term fiscal measures that minimize investor’s risk and ensure an adequate returns on investment. 9 Electricity Market Reforms Removal of barriers to market entry, removing subsidies to fossil fuels and nuclear and the social and environmental costs of polluting energy Department of Electrical and Electronics E ngineering,AITAM,Tekkali

CONCLUSION:

CONCLUSION Wind power is emerging as an environment friendly alternative to meet the ever increasing world demand for electricity, at an affordable price. Department of Electrical and Electronics E ngineering,AITAM,Tekkali
