← TechnologyWhich outcome occurs when rapid voltage fluctuations affect interconnected wind turbine generators?
A)Reactive power injection instability increases✓
B)Generator over-speed triggers stall protection
C)Transformer core saturation reduces efficiency
D)Increased harmonic distortion causes overheating
💡 Explanation
Instability increases because the automatic voltage regulation undergoes phase-locked oscillations (PLO), therefore overcorrecting the grid, rather than balancing generation. PLO causes poor damping and amplified voltages, especially when generation exceeds demand.
