Wind Turbine Technology Quiz

Which of the following disciplines is NOT directly involved in wind turbine technology?

• Aerodynamics

• Mechanics

• Medicine

• Electrical Engineering

What is the primary function of an aerodynamic rotor in a wind turbine?

• Convert electrical energy into mechanical energy

• Capture wind energy and convert it into mechanical power

• Store excess power for later use

• Control the wind direction

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

• To decrease the rotational speed of the rotor

• To store excess mechanical power

• To increase the rotational speed of the aerodynamic rotor

• To convert electrical energy into mechanical energy

Which of the following is NOT a major component of a wind turbine?

• Generator

• Transformer

• Boiler

• Control system

Which type of generator is commonly used in wind turbines?

• DC generator

• Induction generator

• Step-up generator

• Fuel-powered generator

What is the function of the power electronic interface in a wind turbine?

• To store excess energy

• To control wind direction

• To ensure smooth connection between the generator and the power grid

• To decrease wind speed

What is the purpose of the mechanical brakes in a wind turbine?

• To increase the speed of the generator

• To store excess power

• To stop or slow down the turbine in emergency conditions

• To convert wind energy into mechanical energy

Which type of wind turbine operates at a fixed speed?

• Type 1

• Type 2

• Type 3

• Type 4

In a limited variable-speed wind turbine (Type 2), how is the rotor speed controlled?

• By varying the generator speed

• By using an additional rotor resistance

• By using a soft starter

• By changing the gearbox configuration

What is the key advantage of a Vertical Axis Wind Turbine (VAWT)?

• It is more efficient than Horizontal Axis Wind Turbines (HAWTs)

• It can generate power from wind coming from any direction

• It requires a gearbox for operation

• It must always be aligned with wind direction
