contingency reserve restoration period for its interconnection. The contingency reserved
restoration period begins - CORRECT ANSWER ✔✔ -At the end of the disturbance recovery
period
A BES CYBER system can be viewed simply as a grouping of Critical cyber assets - CORRECT
ANSWER ✔✔ -True
A generator's capability for system restoration purpose is determined by what? - CORRECT
ANSWER ✔✔ -Periodic blackstart testing
,A lightly loaded 500 Kv transmission line has a capacitive effect which tends to - CORRECT
ANSWER ✔✔ -Cause high voltage problems that are corrected by placing reactor banks in
service
A proper operating protective relay scheme should normally operate for - CORRECT ANSWER
✔✔ -Faulted system facilities
A shunt capacitor bank with nominal value of 60 MVARS is on a bus with a voltage of .9 p.u.

MVAR
A single control areas disturbance is the sole coase for a frequency dip. The frequency has
stabilized at 59.85 Hz. Manual load shedding is the only option to restore freenacu to 60 Hz. the
entire interconnection load was 10,000 MW at the time of disturbance and all connected
generators have a 5% droop characteristic. Approximately how much load needs to be shed to
restore frequency to 60 Hz - CORRECT ANSWER ✔✔ -500MW
A system disturbance has caused your BA to lose tie line RTUs with a neighboring BA and all
frequency meters which telemetered data into your EMS. How would you operate your GC
system for this scenario? - CORRECT ANSWER ✔✔ -Place all generating units on manual
control and try as best you can to match generation with load
A system in the process of restoration has 1000MW of synchronized generation and 700 MW of
connected load. What amount of load should be shed to raise frequency by .5 Hz - CORRECT
ANSWER ✔✔ -50 MW
, ABC BA has exhausted its native generation capacity and its firm purchases are limited due to
tie line transfer capability to the extent that ABC is not going to be able to meet its native load
plus regulating requirements. In this situation ABC will request that its RC issue a(n)? -
CORRECT ANSWER ✔✔ -Energy Emergency Alert
After a disturbance you have 40% of your load intact, you ACE is near zero and your frequency
is increased for 59.5 Hz you should do what - CORRECT ANSWER ✔✔ -Take no immediate
action
After a disturbance, you have 40% of you load intact, but your frequency keeps declining You
should do what - CORRECT ANSWER ✔✔ -Shed load
After load forecast is completed, the generating units should be assigned by unit commitment to
meet forecasted load and what else? - CORRECT ANSWER ✔✔ -Reserve obligation
All electorice schedule communications shall be in - CORRECT ANSWER ✔✔ -CST
All telecommunication channels shall be - CORRECT ANSWER ✔✔ -Periodically tested or
monitored on-line
An alarm comes in on your SCADA. You notice a bus breaker is showing closed even though
the bus is showing to be de-energized. You notice that a remote line breaker associated with this
bus is shown to be open. What is the cause of this SCADA indication? - CORRECT ANSWER
✔✔ -Breaker failure with a back up relay operation
An interchange transaction has the following energy profile:
Start at 08:00, Stop at 18:00, 60 MW, Ramp tart 07:55, Ramp duration 10 minutes
