How many degrees/second does the turbine yaw?

• A. 0.5
• B. 5
• C. 0.05
• D. 50

Answer: (A)

Yaw rate is the speed at which a wind turbine’s nacelle turns around the vertical axis to face the wind, measured in degrees per second. A rate of 0.5 degrees per second means a full 360-degree turn takes about 12 minutes, giving a smooth, load‑controlled adjustment that minimizes stress on the drivetrain and tower while still tracking wind direction. Faster rates like 5 degrees per second would impose larger transient loads and be harder on the structure; much slower rates like 0.05 degrees per second would be impractically slow to respond to wind changes; and extremely fast rates like 50 degrees per second would exceed the turbine’s inertia and control limits. So 0.5 degrees per second is the best, balanced choice.
