Wind Energy for Cold Climates

Transcripción

1 Conferencia ONRG POWER & ENERGY Wind Energy for Cold Climates VENTUS Project December 2010

2 History The wind has been used as an energy source for a very long time. Persia 900 AD During the Middle Ages, horizontal axis windmills were built in Europe. The classical four-bladed old windmills The windmills lost popularity after the industrial revolution Charles Brush in 1888, one of the first attempts to generate electricity by using the wind

5 Evolution From windmills to turbines Windmills for: pumping water grinding grain Turbines for: generate electricity

6 The wind is not perfect... Wind Power Is not time constant Useful only 30% depend of the location Depend of the mechanic efficiency High impact in place But is free...

7 Size and Applications Small ( 10 kw) Home Farms Remote applications Intermediate ( kw) Communities Hybrids systems Large (660 kw - 2+MW) Wind farms Grid connected Cities

10 Types of turbines For axis Horizontal Axis Wind Turbine or HAWT Lift force 95% of actual turbine Nacelle on top Blade Pitch Control

11 HAWT pros and cons Pros Blade picht control Alta eficiencia, las palas se mueven perpendicularmente al viento Tecnología muy desarrollada Desventajas Necesitan ser montadas en torres altas Elevados costos de transporte, instalación y mantenimiento Poco eficientes a bajas velocidades de viento No funcionan a elevadas velocidades de viento, (la energía es proporcinal al cubo de la velocidad) Problemas de integracion ambiental en las mejores ubicaciones Alto nivel de ruido e interferencias Altos costos de tranporte, especialmente para exportación Necesitan ser direccionadas al viento

13 HAWT integrations

14 Types of turbines For axis Vertical Axis Wind Turbine or VAWT Drag force Nacelle on bottom Without pitch control Low starting torque

15 VAWT pros and cons Pros Without blade pitch control Omni directional No parts moving fast to wind Low starting torque Low level noise and interferences Bird friendly Cons Les efficient than HAWT Low effective area
