AME 11 Q5

1 / 2

With reference to hydraulic governors fitted to alternators designed to run in parallel, explain why these governors have adjustable integral action.

A) To allow the governor to respond more quickly to sudden load changes and reduce the frequency of the alternator.

C) To increase the governor’s sensitivity to small changes in load, which improves the alternator’s synchronization with other units.

D) To prevent the governor from responding to minor fluctuations in the load, reducing wear and tear on the governor mechanism.

B) To ensure that the governor can handle variations in load and maintain stable operation by adjusting the steady-state accuracy.

2 / 2

With reference to hydraulic governors fitted to alternators designed to run in parallel, explain how two generators operating in parallel are able to achieve a stable load share with a 50/50 ratio.

D) By connecting each generator to separate load banks and using separate governors to adjust the load independently, thus ensuring a 50/50 ratio.

B) By using manual load distribution switches to physically adjust the load shared by each generator to achieve a 50/50 ratio.

A) By adjusting the governor settings to ensure each generator automatically compensates for any load imbalances and shares the load equally.

C) By synchronizing the generators' speed and voltage settings, and using governors with equal proportional and integral action to balance the load distribution.
