  1. During a voltage collapse emergency, what is the FIRST priority action for a system operator?

    Answer: Shed load to restore voltage above minimum limits

    Load shedding to restore voltage above minimum acceptable limits is the immediate priority to halt voltage collapse progression.

  2. A major transmission line trips due to a fault and automatic reclosing fails. What is the operator's next step?

    Answer: Attempt a manual reclose after verifying the line is de-energized

    A manual reclose attempt, after confirming the line is safe, is the correct next step when automatic reclosing has failed.

  3. What does the term 'islanding' refer to in power system emergency operations?

    Answer: A portion of the grid operating isolated from the main interconnection

    Islanding occurs when a section of the power system becomes electrically isolated and continues to operate independently from the bulk grid.

  4. Under NERC EOP standards, when must a Transmission Operator notify its Reliability Coordinator of an emergency?

    Answer: As soon as the operator becomes aware of a condition that could impact reliability

    NERC EOP standards require immediate notification to the Reliability Coordinator as soon as a reliability-threatening condition is identified.

  5. A generator trips unexpectedly, causing system frequency to drop rapidly. Which automatic response activates first?

    Answer: Governor response (primary frequency control)

    Governor response is the fastest automatic primary frequency control, reacting within seconds to arrest frequency decline.

  6. During a 'hot restart' of a tripped generator, what is the key concern for the system operator?

    Answer: Synchronizing the unit to the grid at the correct voltage, phase angle, and frequency

    Proper synchronization—matching voltage magnitude, phase angle, and frequency—is critical to prevent damage when reconnecting a generator.

  7. What is the purpose of an 'emergency energy transaction' during a system emergency?

    Answer: To import or export power with neighboring balancing authorities to restore system balance

    Emergency energy transactions allow balancing authorities to exchange power across interconnections to quickly address generation or load imbalances.
