Question: If the frequency bias setting is a more negative value than the frequency response of
a Balancing Authority and a frequency decline is caused by a sudden loss of generation in an
external balancing area, what is the result?
A. ACE will be a positive value and AGC will lower generation.
B. This will not affect ACE.
C. ACE will be a negative value and AGC will increase generation.
D. ACE will be zero and will take no AGC action. - CORRECT ANSWER✔✔C. ACE will be a negative
value and AGC will increase generation.

B. It allows generators to respond to frequency events in proportion to their size
C. It prevents generators from competing with each other when a frequency excursion occurs
D. All answers are correct - CORRECT ANSWER✔✔D. All answers are correct
Question: What is the primary purpose of governor dead band?
A. It helps increase generation when there is an actual Net Interchange flowing out of their
system.
B. It prevents governors from operating during emergency conditions.
C. It helps arrest and stabilize the frequency decay.
D. It prevents governors from operating when slight variations occur in the system's frequency. -
CORRECT ANSWER✔✔D. It prevents governors from operating when slight variations occur in
the system's frequency.
