1. ECOTECNIA 100: On-shore Multi Mega-Watt Windturbine Juan Mª Cámara 28th February 2006

2. Setting the new standard for on-shore application 100m - 3 MW

3. 19812006 The size Wind turbine development

4. Offshore Onshore The size Future evolution trends

5. Use oriented design Lifecycle DesignManufactureInstallationOperation

6. Electrical capacity Simultaneous full range operation at nominal power Operating temperature 40 °C Operating Voltage 90 % Reactive Power Supply 30 %

7. Noise requirements Low speed rotation to reduce noise inmission At low level noise, the difference in rotational speed pays a important role 100m 500m

8. Main figures for transport and installation LengthWeightCross dim. Blade48,3 m9,8t3x3x50m TowerMax. 30 m30tDia. 4,30 Nacelle9,5 m100 t4.3 x 3,9 m (h) Rotor5 m25 t4,3 x 4,5 m Logistics

9. Nacelle Complete drive train, from rotor to HV

10. Nacelle Complete drive train, from rotor to HV

11. Nacelle Approach on logistics challenge

12. Supporting estructure Low weight, direct rotor support since 1983

13. Excellent mass - stiffness ratio: Only 9.8 tons without use of carbon fiber Wind class IEC IIA : 3 m Prebend Up to date aerodynamics; New profiles DU and experienced NACA Stronger and more compact Superroot: Root diameter 2.4m, 84 x M36 Bolts The Blade Specific design, 48 m length, 4 m largest chord

14. The tower The other side of the logistic challenge The tower is built, without dynamic compromises, in steel up to 80 m height with the transport requirements of diameter smaller than 4.3 m. Hybrid towers are designed taller hub height

15. Power 3,000 kW Rotor Three bladed, 100 m diameter Class II A with upwind Rotor speed 7.5 r.p.m. -14.25 at nominal power Operation From 3 m/s to 25 m/s 10 min. Avg. Gearbox Type Planetary, parallel shafts Weight 35 t Generator Type 4 pole Induction with wound rotor TransformerIncluded up to 30 kV General characteristics Nacelle Turbine

16. Bottom diameter 5 m Top diameter 2.7 m Height 90 m to 110 m Power control Vectorial control generator-inverter Speed control Pitch control Main brake Independent pitch control Auxiliary brake Independent emergency system Yaw Active, with mechanical brake Voltage deep Capacity to maintain operation during voltage deep General characteristics Tower Control
