c. Tie Lines - For the ACE equation to work properly, dynamic schedules, pseudo
ties, frequency calculations, and all ________ must be metered.
a. Communications
b. Transformers
c. Tie Lines
d. Generation
c. Energy Emergency Alert Level I - What Energy Alert Level would the following
example be categorized as?
"A Balancing Authority, Reserve Sharing Group, or Load Serving Entity foresees,
or is experiencing conditions where all available resources are committed to meet
firm load, firm transactions, etc, and requests an Energy Emergency Alert."
,a. Energy Emergency Alert Level IV
b. Energy Emergency Alert Level III
c. Energy Emergency Alert Level I
d. Energy Emergency Alert Level II
b. Implement the appropriate congestion management procedure. - You are a
Reliability Coordinator in the Eastern Interconnection. A flow gate has become
overloaded because a parallel 345kV line has relayed out and part of that load has
transferred over to the flow gate causing an SOL and possible IROL violation.
What would you do to relieve this violation?
a. Notify another Reliability Coordinator and ask them if they are having any
problem, and what should you do.
b. Implement the appropriate congestion management procedure.
c. Issue a Transmission warning to the Transmission Operators that lost the 345kV
line.
d. Place the line back in service within 30 minutes.
b. Adjacent Balancing Authorities - Interchange schedules may be implemented
between _______________________.
a. Source and Sink Balancing Authorities
b. Adjacent Balancing Authorities
c. Sending, Receiving and Intermediate Balancing Authorities in the same Region.
d. Balancing Authorities in the same Interconnection.
a. Frequency will continue to drop, generator governor response, decrease in load.
- When the frequency of an Interconnection decreases due to the loss of a large
generator, the ________________ until the combination of both ____________
and ______________ replace the output of the lost generator.
, a. Frequency will continue to drop, generator governor response, decrease in load
b. Frequency will continue to drop, generator governor response, voltage
regulating transformer response
c. Voltage will continue to raise, generator AVR response, voltage regulating
transformer response
d. Voltage will continue to raise, generator AVR response, decrease in load
a. That all involved reliability entities determined that there is no reliability
problems with the Arranged Interchange. - In developing and setting up an
Arranged Interchange, which of the following would transition the Arranged
Interchange to the Confirmed Interchange status?
a. That all involved reliability entities determined that there is no reliability
problems with the Arranged Interchange.
b. The Department of Energy (DOE) made an in-depth study of the Interchange
Agreement and determined that it would have an adverse affect on the
Interconnection.
c. There are available resources to meet the load.

with this Interchange Agreement.
b. He violated NERC standards - Early in the afternoon, a system operator notices
