← TechnologyIn a wind turbine's pitch control experiencing high winds, which outcome occurs when the control algorithm oscillates?
A)Resonant structural fatigue emerges✓
B)Generator torque output stabilizes
C)Aerodynamic stall margin increases
D)Blade tip speed converges quickly
💡 Explanation
Resonant structural fatigue emerges because the pitch control system induces oscillations matching the tower's natural frequencies; this triggers a positive feedback loop via the **control loop gain**, therefore increasing stress, rather than stabilizing torque due to constant pitch adjustments.
