← TechnologyIn a wind turbine with stall-regulated blades, which outcome occurs when wind speed exceeds operational limits?
A)Turbine speed remains approximately constant✓
B)Increased lift maximizes power extraction
C)Blade pitch actively reduces airflow
D)Generator output dramatically increases quickly
💡 Explanation
Turbine speed approximates constancy because stall regulation induces turbulent airflow via stall, which reduces the angle of attack and lift. Therefore the turbine is protected, rather than increasing lift or generator output if stall didn't engage automatically.
