 How do we obtain windenergy? The technique behind windenergy by Jesse Voorhorst en Constantijn van der Eijk

What kind of windmills do exist?  Two types  Horizontal axis wind turbine (HAWT)  Most in use  Vertical axis wind turbine (VAWT)  In development

HAWT

VAWT

How is a wind turbine built?

What are wind turbines made of?  3-blade HAWT: metal or concrete  Rotorblades: epoxy resin  VAWT: it differs

What are the criteria a wind turbine has to meet?  several rules and standards  Construction  Maintainance  Achievement  Grid connection  Certification is possible, by appointed companies only  Standards not binding, yet convenient  Standards more elaborate than legislation

 Mostly three rotor blades  for energy rotor blades at an angle with the wind direction  Capstan motor turns when necessary How is wind converted into energy? rotor blade blade adjustment drive brake gauges generator gondola rotating axis stairs tower grid connection foundation rotor hub

How is wind converted into energy?  Most devices in gondola  Gearbox increases speed  Sometimes left out  Generator  Works similar to a dynamo  Axis rotates within stator  Contains spools of copper wire  Copper wire delivers electrial current main bearing computer generator wind direction/ speed brake disc gearbox main axis gearwheel rotor blade capstan motor

How is wind converted into energy?  Output tension 650 V  Transformed up to 3 to 50 kV  Transformer  2 spools  Number of turns determines tension  2 x more turns on secundary side  2x more tension  Magnetic field primairy side secundary side

Under what conditions do wind turbines produce energy?  Sufficient wind

How is energy transported?  Connected to the local grid  Correct tension  Transformer station  Avoid distortion power  Current flows into the grid

What is the energy yield?  Depends on type of wind turbine  Subject to:  design  height  length of rotor blades  windspeed  location  VAWT suitable for urban areas

What is the energy yield?
