Wind the Miller

What are the five basic parts of a wind turbine?

• Hub, Rotor, low speed shaft, high speed shaft, and the cooling unit

• Low speed shaft, and high speed shaft

• CPU, RAM, Hard drive, Video card, and Motherboard

• Cables

How does a wind turbine generate electricity?

• The wind pushes the blades which then makes it all fall over

• The wind does nothing and nothing happens

• The wind turns the rotor of the wind turbine, which makes electricity

• The worker physically pushes the blades to make electricity

What are the parts which make up the tower?

• Cables, Cross braces, Mid-tower junction box, Utility box, and the Ladder

• Blade

• Nacelle

• Rotor

How do they help the tower work?

• The cables helps the tower by delivering energy generated by wind turbine.

• The Mid-tower junction box helps the tower by securing the wires

• The Utility box helps the tower by electrical communication

• the Ladder helps the tower by letting employees on the top of it

What are the parts which make up the nacelle?

• Anemometer

• Mechanical brake

• Rotor, Gearbox, Generator, Yaw motor, and the controller

• Sandwich

How do they help the nacelle?

• The rotor helps the nacelle by catching the wind and spins the main shaft.

• The gearbox helps the nacelle by converting the rotation of the rotor from 22RPM into 1500RPM for the generator

• The generator helps the nacelle making usable electricity using magnets and copper wire

• The controller helps by telling the yaw motor to move the nacelle; monitors other turbine activity

• The yaw motor helps the nacelle by turning the nacelle to face the wind; responds to the controller

The gearbox changes the turning force so that is has to go ­­­­­­­­­­­­­­­­­­­­­­­­­­­­____________ with less ______________ in every revolution.

• Faster; Force

• Slower; Power

The two types of brakes on a wind turbine are the ________________________ and the_________________________________.

• Drum brakes; Disk brakes.

• Car brakes: That taco bell taco

True or False – The wind turbine is controlled by one computer, called the controller.

• False

• True

At what speed is the wind turbine stopped so that damage does not occur?

• 27 meters per second

• 25 meters per second

• 42 meters per second
