    1. 1. Wind Power Energy-A growth engine for Energy System By, Ishan Shah(10BPE200) Bhavik Patel(10BPE225)
    2. 2. Wind Power???• Operation which produces power plentiful, renewable, with no GHGs emissions during operation.• Any effects on the environment are generally less problematic than those from other power sources.• In 2011, 83 countries around the world, using wind power on a commercial basis• As of 2010, wind energy was over 2.5% of total worldwide electricity usage, growing at more than 25% per annum. 1/5/2013 2
    3. 3. Availability of Source • The earth receives about 1.7 x 1017 watts of power per hour from the sun • About 1-2% of this energy is converted to wind energy (of order 1015)1/5/2013 3
    4. 4. Wind Turbine• Wind turbine obtains its Generator power input by converting the force of the wind into a torque acting on the rotor blades. Electric Grid• The amount of energy which the wind transfers to the rotor depends on the Electricity Density of air, Wind Speed, Rotor area Hence several design considerations must be taken into consideration for turbines and generators. 1/5/2013 4
    5. 5. Commercial Users• Several countries have already achieved relatively high levels of penetration, in stationary (grid) electricity production 1. 28% in Denmark (2011), 2. 19% in Portugal (2011), 3. 16% in Spain (2011), 4. 14% in Ireland (2010) and 5. 8% in Germany (2011).

    8. 8. Moving to offshores… Walney Offshore Windfarm Figure 51/5/2013 8
    9. 9. One step forward…. Floating wind turbine• Not limiting to near shores, but going far away in oceans• A floating wind turbine is an offshore wind turbine mounted on a floating structure that allows the turbine to generate electricity in Hywind, being assembled in water depths where Amoy Fjord near Stavanger, bottom-mounted towers Norway are not feasible Figure 6 Source: IWES1/5/2013 9
    10. 10. Advantages of wind energy • The wind blows day and night, which allows windmills to produce electricity throughout the day. • Energy output from a wind turbine varies with change in wind flow rate but is compensated to some extent by the inertia of the wind turbine rotor. • Wind energy is a renewable source of energy that generates no pollution and has little environmental impact. • Up to 95 percent of land used for wind farms can also be used for other profitable activities including farming, foresting, ranching.1/5/2013 10
    11. 11. Not everything is perfect & some challenges….. • Non-Dispatch able • Location Dependent • With present technology and demand it can meet only a part of electricity demand. • little environmental impacts.1/5/2013 11
    12. 12. Environmental effects• Compared to the environmental impact of conventional energy sources, the environmental impact of wind power is relatively minor. Wind power consumes no fuel, and emits no air pollution, unlike fossil fuel power sources.• Birds often collide with high voltage overhead lines, masts, poles, and windows of buildings. They are also killed by cars in traffic. However, birds are seldom killed by wind turbines as it is commonly misunderstood1/5/2013 12
    13. 13. Wind V/S Natural Gas Wind Natural Gas Low Operating cost High operating cost Low fuel hike risk Subjective to fuel hike No emissions Various Green-House Gas emissions High capital Cost Low to high capital cost Non-dispatch able Dispatch able.1/5/2013 13
    14. 14. Technological DevelopmentThe main issues in the ongoing technological development are• Improvement of mechanical components (gearboxes, bearings, blades)• Development of feasible foundation concepts• Improvement of electrical components (generators, transformers)• Improvement of the siting process• Improvement of installation and commissioning processes1/5/2013 14
    15. 15. ConclusionThe main purposes of research in wind energyare to: decrease the cost of power generated by the wind; • increase the reliability and predictability of the energy source; • investigate and reduce the adverse environmental impact of massive deployment of wind turbines; • build research based educations for wind energy engineers1/5/2013 15
