If two turbo-generators with the same no-load speed settings are operating in parallel, the unit whose governor has the lesser speed droop will __________.

Official USCG Answer & Rule Citation

Correct Answer: Option D — assume the larger share of the load

Speed droop dictates how much a governor decreases speed as load increases. When operating in parallel, the unit with the lesser speed droop exhibits a steeper load-frequency response characteristic, thus assuming a significantly larger share of the total electrical load.
