← TechnologyWhich consequence results when grid-connected wind turbine's synchronization circuit is damaged?
A)Reactive power injection increases
B)Stable grid voltage is maintained
C)Mechanical overspeed protection activates
D)The circuit breaker fails synchronizing✓
💡 Explanation
If damaged, the synchronization circuit cannot correctly match phase, frequency and voltage. Because successful parallel operation cannot occur due to missed synchronization, the circuit breaker fails, therefore disconnecting from grid, rather than allowing asynchronous connection.
