Which type of wind turbine is commonly used for small-scale applications, such as powering a single home or farm?

  1. Horizontal Axis Wind Turbine (HAWT)

  2. Vertical Axis Wind Turbine (VAWT)

  3. Darrieus Wind Turbine

  4. Savonius Wind Turbine

Show answer
Correct Option: B
Explanation:

VAWTs are often used for small-scale applications due to their ability to operate in low-wind conditions and their compact design.

What is the primary advantage of HAWTs over VAWTs?

  1. They can generate more power at higher wind speeds.

  2. They are more efficient in converting wind energy into electricity.

  3. They are quieter in operation.

  4. They require less maintenance.

Show answer
Correct Option: A
Explanation:

HAWTs are more efficient at capturing wind energy at higher wind speeds due to their larger rotor diameter and higher blade tip speed.

Which type of wind turbine is characterized by its eggbeater-like shape and ability to generate power from wind blowing in any direction?

  1. HAWT

  2. VAWT

  3. Darrieus Wind Turbine

  4. Savonius Wind Turbine

Show answer
Correct Option: C
Explanation:

Darrieus wind turbines have a unique eggbeater-like shape and can generate power from wind blowing in any direction, making them suitable for areas with variable wind conditions.

What is the main advantage of Savonius wind turbines compared to other types?

  1. They are self-starting even at low wind speeds.

  2. They can operate in turbulent wind conditions.

  3. They are more efficient in converting wind energy into electricity.

  4. They produce less noise pollution.

Show answer
Correct Option: A
Explanation:

Savonius wind turbines are known for their ability to self-start even at low wind speeds, making them suitable for areas with weak or inconsistent wind conditions.

Which component of a wind turbine is responsible for converting the kinetic energy of the wind into rotational energy?

  1. Rotor

  2. Nacelle

  3. Tower

  4. Generator

Show answer
Correct Option: A
Explanation:

The rotor, consisting of blades attached to a hub, is the primary component that captures the wind's kinetic energy and converts it into rotational energy.

What is the purpose of the nacelle in a wind turbine?

  1. It houses the generator and other electrical components.

  2. It supports the rotor and blades.

  3. It transmits power to the grid.

  4. It controls the turbine's yaw mechanism.

Show answer
Correct Option: A
Explanation:

The nacelle is the enclosed housing that contains the generator, electrical components, and control systems of the wind turbine.

Which type of wind turbine is typically used for large-scale wind farms and has a horizontal axis of rotation?

  1. HAWT

  2. VAWT

  3. Darrieus Wind Turbine

  4. Savonius Wind Turbine

Show answer
Correct Option: A
Explanation:

HAWTs are the most common type of wind turbine used in large-scale wind farms due to their high efficiency and ability to generate large amounts of power.

What is the function of the tower in a wind turbine?

  1. It supports the rotor and nacelle.

  2. It transmits power to the grid.

  3. It controls the turbine's yaw mechanism.

  4. It houses the generator and other electrical components.

Show answer
Correct Option: A
Explanation:

The tower is the tall structure that supports the rotor, nacelle, and other components of the wind turbine.

Which type of wind turbine is characterized by its vertical axis of rotation and ability to generate power from wind blowing from any direction?

  1. HAWT

  2. VAWT

  3. Darrieus Wind Turbine

  4. Savonius Wind Turbine

Show answer
Correct Option: B
Explanation:

VAWTs have a vertical axis of rotation and can generate power from wind blowing from any direction, making them suitable for areas with variable wind conditions.

What is the primary advantage of Darrieus wind turbines over Savonius wind turbines?

  1. They can generate more power at higher wind speeds.

  2. They are more efficient in converting wind energy into electricity.

  3. They are quieter in operation.

  4. They require less maintenance.

Show answer
Correct Option: A
Explanation:

Darrieus wind turbines are more efficient at capturing wind energy at higher wind speeds due to their larger rotor diameter and higher blade tip speed.

Which component of a wind turbine is responsible for converting the rotational energy of the rotor into electrical energy?

  1. Rotor

  2. Nacelle

  3. Tower

  4. Generator

Show answer
Correct Option: D
Explanation:

The generator is the component that converts the rotational energy of the rotor into electrical energy.

What is the purpose of the yaw mechanism in a wind turbine?

  1. It keeps the rotor facing into the wind.

  2. It controls the speed of the rotor.

  3. It transmits power to the grid.

  4. It stops the turbine in high winds.

Show answer
Correct Option: A
Explanation:

The yaw mechanism is responsible for keeping the rotor facing into the wind to maximize power generation.
