Worked Solution & Example Answer:Study the sectional view of a wind turbine below - NSC Agricultural Technology - Question 3 - 2016 - Paper 1
Step 1
Identify parts A and B of the wind turbine above.
Answer
A is the Rotor/Propeller (nose cone, head) which captures wind energy and converts it into rotational energy. B is the Gearbox (transmission, gear) which is responsible for increasing the rotational speed of the rotor to the generator.
Step 2
Step 3
Name and describe TWO devices installed on a wind turbine to ensure maximum efficiency of the turbine blades.
Answer
- Wind direction meter: This device orients the rotor/propeller properly into the wind to ensure optimal energy capture.
- Wind speed meter: This instrument measures the wind speed to adjust the pitch of the blades for maximizing energy efficiency, allowing the turbine to operate effectively in varying wind conditions.
