Differential relay

Under frequency load shedding is set-up so that which of the following does NOT occur?
Uncontrolled separation

Who is responsible to make sure that the operation of voltage control equipment is coordinated with other impacted entities?
Transmission Operator

The coordination of voltage schedules by system operators would be utilized to reduce all of the following EXCEPT?
Reactive inadvertent

What should a system operator expect to see if the generator increases its excitation?
An increase in MVAR output

A transmission line between Bus A and Bus B has MW flow from Bus B to Bus A. After the tripping of a parallel line, the line flow from Bus B to Bus A exceeds the lines thermal rating. Which of the following actions would assist the operator in correcting the problem?
Increase generation at Bus A

What is a major concern for a System Operator during emergency conditions?
System remains connected to the Interconnection

If your system has lost a large amount of customer load due to a system disturbance, but has remained connected to all of your neighbours, what is the best solution to consider?
Coordinate with the neighbours

You report for work on a peak summer day with expected high temperatures and load. What can you do to maintain an adequate system voltage profile?
Get under the voltage by placing capacitors in service while maintaining operating limits

If a Balancing Authority is unable to calculate ACE for more than _________ minutes it shall notify its Reliability Coordinator.

Your system configuration presents you with a situation of having two parallel lines between two stations. The lines have different ratings. Line A has a rating of 250 MVA, while line B has a rating of 200 MVA. Based on the line ratings, what is the first contingency transfer capability between the two stations?
200 MVA
