    1. Wind Turbines

    2. Drag-type turbines Persian windmill Chinese wind wheel Saviounus Lift-type turbines VAWT, Vertical Axis Wind Turbine Darrieus HAWT, Horizontal Axis Wind Turbine The Danish concept American multiblade Grumman windstream Different types of wind turbines

    3. Drag-type turbines Savonious The Persian windmill The Chinese wind wheel

    4. Drag-type turbines Ref: www.ifb.uni-stuttgart.de/~doerner/edesignphil.html

    5. Lift-type turbinesVAWT, Darrieus

    6. Lift-type turbinesVAWT, Darrieus

    7. Ref: www.ifb.uni-stuttgart.de/~doerner/edesignphil.html

    8. Lift-type turbinesHAWT, American Multiblade

    9. Lift-type turbinesHAWT, Grumman Windstream

    10. The blades upwind the rotor Constant speed on the rotor Power output limitation Stall control Brakes Mechanical Aerodynamic Lift-type turbinesHAWT, The Danish Concept

    11. Development of HAWT HEIGHT [M]

    12. Wind power and energy A • Power output from wind turbines: • Energy production from wind turbines: C

    13. Energy flux for wind turbines Where: P = Power [W] r = Density [kg/m3] c = Velocity [m/s] A = Area [m2] h = Efficiency [ - ] Recommended literature: Wind Turbine Technology, David A. Spera, ISBN no. 0-7918-1205-7

    14. The world’s energy potential for land based wind turbines Estimated energy output in kWh/kW from a wind turbine that are dimensioned for 11 m/s

    15. Global Installed wind power

    16. Installed wind power Source: www.gwec.net

    17. Wind power capacity global forecast

    18. Energy goal for 2010: 3 TWh Wind farms in operation: Number of wind farms: 13 Number of wind mills: 165 Installed power: ca. 320 MW Energy production: ca. 900 GWh Planned wind farms (License is given, but not built) Number of wind farms: 15 Number of wind mills: 439 Installed power: 1214 MW Energy production: 3866 GWh Planned wind farms (Applied for License) Number of wind farms: 36 Number of wind mills: 1444 Installed power: 4496 MW Wind Power in Norwayper 1st January 2006 Hitra
