c. Return outaged equipment to service
d. Request a voltage reduction. Answer: c. Return outaged equipment to
service
● 3. If your transmission path is rated for 1200 MW and 1000 MW are
scheduled on it, but due to parallel flows the actual flow is 1300 MW,
what action should you take?
a. Request that a phase shifting transformer be installed
b. Reduce interchange transactions impacting the path
c. Request all parallel flow to PSEs to increase schedules
d. Reduce all commercial customer load. Answer: b. Reduce interchange
transactions impacting the path
,● 4. If your system is MVAR deficient, what action could be
implemented to prevent voltage collapse?
a. Raise system frequency above 60.5 Hz
b. Shed firm load in the deficient area
c. Separate from the Interconnection
d. Lower transmission voltages. Answer: b. Shed firm load in the
deficient area
● 5. Which of the following actions can a system operator take in order
to maintain stability on the system?
a. Request generators to absorb maximum MVAR
b. Place all operating limits on dynamic calculation
c. Raise system voltages as high as possible, but within their operating
parameters
d. Reduce voltages on the transmission system. Answer: c. Raise system
voltages as high as possible, but within their operating parameters
● 6. Which of the following actions should you take if an outage on a
neighboring system has caused a violation on your system?
a. Open all tie-lines to your neighbor
b. Ask the Reliability Coordinator for assistance
,c. Shed load to mitigate the violation
d. Wait for the neighboring system to contact you. Answer: b. Ask the
Reliability Coordinator for assistance
● 7. If a SOL or IROL violation occurs due to transfers across the
system and it is determined that parallel flows are contributing to the
violation, what should the system operator do?
a. Place all system capacitors in service
b. Reduce system load
c. Inform the Reliability Coordinator
d. Dump firm load. Answer: c. Inform the Reliability Coordinator
● 8. While performing a pre-outage study, you identify that the
transmission outage will cause a thermal violation on a parallel path,
which of the following actions would be the first one you would
implement?
a. Shed load to mitigate the concern
b. Allow the outage to occur and see what happens
c. Reschedule the outage if possible
d. Allow the outage to take place as long as no load is lost. Answer: c.
Reschedule the outage if possible
, ● 9. Which of the following actions should the system operator
implement first if transmission line limits exceed the facilities
emergency limits based on a contingency that has not yet occurred, but
their protocols are to respond on a pre-contingency basis?
a. Reduce voltages in the area of the violation
b. Remove the facility from service
c. Curtail any interchange transactions that are curtailable
d. Only implement actions if the contingency occurs. Answer: c. Curtail
any interchange transactions that are curtailable
● 10. If a Reliability Coordinator had to implement any type of line
loading relief procedures, which of the following entities would they be
coordinated with? Pick two.
