1. What is the primary function of a nacelle in a wind turbine?
A. Support the tower
B. Store generated power
C. House major mechanical and electrical components
D. Control blade pitch
Rationale: The nacelle contains key components such as gearbox,
generator, and control systems.
2. Which component adjusts the blade angle to control power and loads?
A. Gearbox
B. Pitch system
C. Yaw bearings
,D. Anemometer
Rationale: The pitch system rotates blades around their axis to optimize
aerodynamic performance.
3. The yaw system is responsible for:
A. Stopping the turbine during high wind
B. Orienting the rotor into the wind
C. Supporting the main shaft
D. Adjusting rotor speed
Rationale: Yaw motors and gears rotate the nacelle so blades face the
wind direction.
4. Which type of braking system is used for emergency stopping?
A. Aerodynamic only
B. Hydraulic only
C. Mechanical disc brake
D. Electrical resistance brake
Rationale: Mechanical brakes provide reliable backup braking during
faults.
5. Typical cut-in wind speed for large turbines is:
A. 1–2 m/s
B. 3–4 m/s
C. 6–7 m/s
D. 10 m/s
Rationale: Turbines begin generating power around 3–4 m/s.
, 6. What is the cut-out wind speed for most utility-scale turbines?
A. 10 m/s
B. 15 m/s
C. 25 m/s
D. 35 m/s
Rationale: Turbines stop above ~25 m/s to protect equipment.
7. Which gearbox design is most common in Suzlon wind turbines?
A. Direct drive
B. Friction gear system
C. Planetary-parallel combination
D. Worm gear
Rationale: Planetary stages allow compact design and high torque
transmission.
8. The main shaft connects the rotor hub to the:
A. Control cabinet
B. Tower foundation
C. Gearbox
D. Yaw drive
Rationale: The low-speed shaft transfers rotor torque into the gearbox.
9. Which generator type is widely used in Suzlon turbines?
A. DC generator
B. Squirrel cage induction generator
C. Doubly-fed induction generator (DFIG)
