If multiple lines trip resulting in parallel lines overloading and voltage decreasing,
the system operator should first consider which mitigating actions?
Re-dispatch or bring on additional generation
Shed load to reduce the powerflow on the overloaded lines
Open the line breakers to the overloaded lines.
Curtail Interchange Scheduled to the low voltage area - ANSWER>>Re-dispatch or
bring on additional generation
A Balancing Authority foresees or is experiencing conditions where all available
resources are committed to meet firm load, firm transactions. The BA should
request which level of the Energy Emergency Alerts?
Energy Emergency Alert Level 1
Energy Emergency Alert Level 4
Energy Emergency Alert Level 2
Energy Emergency Alert Level 3 - ANSWER>>Energy Emergency Alert Level 1
,The System Operator experiences a major transmission system disturbance which
results in a large loss of load. Which of the following results is most likely to
occur?
an increase in system frequency
an increase in system voltage in a wide-area
a decrease in system voltage
a decrease in system frequency - ANSWER>>an increase in system frequency
A Balancing Authority is assessing its system by reviewing the frequency at
locations in its area and notices a frequency reading at one location varies
significantly from the other locations. What might the Balancing Authority
conclude?
AGC is not working correctly.
Interchange schedules are not correct.
Frequency bias is not correct.
An island condition has occurred - ANSWER>>An island condition has occurred
A Transmission Operator is implementing their system restoration plan after a
major system disturbance. When they are ready to energize a blacked out area,
the system operator must .
Close any capacitor banks which are open
Increase blackstart generator to maximum output
Turn all voltage regulators to the manual position
Isolate the load - ANSWER>>Isolate the load
When a Balancing Authority has exhausted all other options and can no longer
provide its customers' expected energy requirements, what can be used to obtain
needed capacity and energy?
Capacity Warning
Demand Alert
Imbalance Event
Energy Emergency Alerts - ANSWER>>Energy Emergency Alerts
,The Interconnections is not experience any disturbances or overloads. A Balancing
Authority notifies the Reliability Coordinator that the projected load in a
Balancing Area for the next three hours (over the morning peak) is trending above
the available generation that had been committed for the day. Operating
Reserves will be required to be converted into energy to cover the shortfall. What
is the most likely cause of the shortfall?
The largest capacity generator in the Balancing Area tripped off line.
The Load Forecast for the day was greatly underestimated.
A generator operator failed to notify the Balancing Authority that one of their
generators was de-rated by 30% of its capacity.
There was a curtailment of the largest import on the Interchange Schedule. -
ANSWER>>The Load Forecast for the day was greatly underestimated.
The coordination of the emergency operating plans the Transmission Operator
and Balancing Authority shall include which of the following?
Process to prepare for and mitigate Emergencies
All the above.
Cancellation of transmission or generator outages
Roles and responsibilities for activating operating plan - ANSWER>>All the above.
A Balancing Authority anticipating an operating capacity or energy emergency
shall perform all actions necessary including
1) bringing on all available generation
2) postponing equipment return
3) scheduling interchange sales
4) being prepared to reduce firm load.

3 and 4 - ANSWER>>1 and 4
A System Operator is in the process of restoring load after a system collapse. The
system currently has three generators online with a combined capacity of 1200
MWs. Current load on the system is 500 MWs. What is the maximum load that
, the System Operator can restore at one time without risking the re-collapse of the
system.
80 MWs
35 MWs
60 MWs
25 MWs - ANSWER>>60 MWs
Under Frequency Load Shedding (UFLS) is to stabilize the imbalance between
generation and load that has been created by a system disturbance. This is
accomplished by .
Shedding load prior to generation tripping
Shedding all load to arrest frequency
Voltage reduction on the distribution system.
Tripping generation first - ANSWER>>Shedding load prior to generation tripping
A Balancing Area has separated from the Interconnection during a severe thunder
storm and is in a blackout condition. Several plants tripped off-line including a 200
MW blackstart capable unit and a blackstart capable hydro plant located 175
miles from the load center connected by a 345 kV system. What actions should
the BA take to restore the area?
Close all the breakers that tripped to the blackstart capable units.
Isolate the transmission paths into the power plants, Bring the 200 MW blackstart
unit on line to support the power plants auxiliaries, Add load in 10 MW blocks
while increasing generation, Bring on additional generation.
Open all breakers in area first then isolate the transmission paths into the power
plants.
Isolate the transmission paths into the power plants. Order the hydro plant on
line and begin energizing customer loads. - ANSWER>>Isolate the transmission
paths into the power plants, Bring the 200 MW blackstart unit on line to support
the power plants auxiliaries, Add load in 10 MW blocks while increasing
generation, Bring on additional generation.
