If a 500 kV transmission line with a surge impedance loading of 800 MW is currently loaded at 1400 MW, which of the following events would most likely occur? a. Generator MVAR output would increase b. All system capacitors would trip off-line c. Generator MVAR output would decrease d. All automatic reactors would connect to the system - ANSWER a. Generator MVAR output would increase 2. When system conditions are such that emergency procedures are expected to be implemented, which of the following actions should be considered first? a. Shed firm load b. Implement Active Load Management 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.

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.
