An 800 MW generator trips in a Balancing Authority
external to your Balancing Authority Area. Which of
the following indications would you expect to see in
your area?
A) Net Actual Interchange would decrease
significantly.
B) ACE would drop to approximately -800 MW.
C) Frequency would drop, and ACE would remain
relatively unchanged.
D) Frequency would drop, and ACE would increase
significantly. - ...ANSWER...C) Frequency would drop,
and ACE would remain relatively unchanged.
,When is the only time voltage reduction for load relief
is acceptable on the transmission system?
A) When voltage on the distribution system is already
low.
B) It is acceptable anytime load relief is needed.
C) When the system is separated from the
Interconnection.
D) When Interconnection frequency is above 60.00 Hz.
- ...ANSWER...C) When the system is separated from
the Interconnection.
In system restoration, priority should be given to:
A) Restoring customer load as quickly as possible.
B) Reporting disturbance to NERC and DOE.
C) Restoring auxiliary power to off-line generators.
D) Restoring power to critical facilities. -
...ANSWER...D) Restoring power to critical facilities.
If a Balancing Authority or Reserve Sharing Group is
experiencing conditions where all available resources
are committed to meet firm load, firm transactions, and
reserve commitments, what does the deficient entity
need to request their Reliability Coordinator to issue?
A) Energy Emergency Alert Level 3
,B) Energy Emergency Alert Level 1
C) Energy Emergency Warning
D) Energy Emergency Alert Level 2 - ...ANSWER...B)
Energy Emergency Alert Level 1
A Transmission Operator's Emergency Operating Plan
states when voltages fall below .87 per unit (p.u.) or
87% of nominal voltage and remains at that level for a
sustained period of 10 minutes or longer, manual load
reduction actions are required. When the system voltage
returns to .9 p.u. or 90% manual load disconnection is
not required.
If a generator trips off line within the BA and the
nearby 230 kV system voltage immediately drops to
200 kV and remains at that level for the next 3 minutes.
What is the BA required to do?
A) Wait 7 minutes for the remaining generator AVRs to
respond; close capacitor banks; adjust Transformer
Taps.
B) Immediately disconnect firm system load until the
voltage returns to at least .9 p.u. Notify the RC of the
amount of load disconnected.
C) Immediately take actions to raise the voltage
EXCEPT removing firm system load. Notify the RC
and neighboring BA's. Prepare for manual load
reduction if the voltage remains below 9 p.u over the
, next 7 minutes - ...ANSWER...C) Immediately take
actions to raise the voltage EXCEPT removing firm
system load. Notify the RC and neighboring BA's.
Prepare for manual load reduction if the voltage
remains below .9 p.u. over the next 7 minutes.
A condition when a Load-Serving Entity has exhausted
all other options and can no longer provide its
customers' expected energy requirements is referred to
as ____________?
A) Energy Emergency
B) Energy deficiency
C) Load shortage
D) Energy shortage - ...ANSWER...A) Energy
Emergency
You are currently in the early stages of restoration with
600 MWs of synchronized generation. There is 200
MWs of spinning reserve available. To maintain
acceptable frequency control, what is the largest block
of load that can be restored at one time?
A) 10 MWs
B) 20 MWs
C) 30 MWs
D) 60 MWs - ...ANSWER...C) 30 MWs
If firm Load shed is imminent or in progress, what level
Energy Emergency Alert is required?
