You are a Reliability Coordinator in the Eastern Interconnection. A flow gate has become
overloaded because a parallel 345kV line has relayed out and part of that load has
transferred over to the flow gate causing an SOL and possible IROL violation. What would
you do to relieve this violation?
a. Notify another Reliability Coordinator and ask them if they are having any problem, and
what should you do.
b. Implement the appropriate congestion management procedure.
c. Issue a Transmission warning to the Transmission Operators that lost the 345kV line.
d. Place the line back in service within 30 minutes. - ANSWER b. Implement the
appropriate congestion management procedure.
Interchange schedules may be implemented between _______________________.
a. Source and Sink Balancing Authorities
b. Adjacent Balancing Authorities
c. Sending, Receiving and Intermediate Balancing Authorities in the same Region.
d. Balancing Authorities in the same Interconnection. - ANSWER b. Adjacent
Balancing Authorities

, b. Frequency will continue to drop, generator governor response, voltage regulating
transformer response
c. Voltage will continue to raise, generator AVR response, voltage regulating transformer
response
