notify other Reliability Coordinators include which of the
following?
1. Sabotage events
2. Interconnection Reliability Operating Limit violations
3. Voltage reductions
4. Insufficient resources
5. Arming of special protection systems

NERC Standard IRO-014 speaks to the Coordination Among
Reliability Coordinators. In additional to Operating
Procedures, Operating Processes, and Operating Plans that
require notification or coordination of actions that may
impact adjacent Reliability Coordinator Areas, the Reliability
Coordinator shall notify other impacted Reliability
Coordinators upon identification of an expected or actual
Emergency in its RC Area.
Question>> 2
Each Transmission Operator is required to have a system
Page 1 of 63
,restoration plan. What is the first thing a Transmission
Operator must do when energizing a blacked out area?
Turn all voltage regulators to the manual position. Close any
capacitor banks which are open.
Isolate the load.
Contact the Regional Reliability Organization.
Answer>>
Isolate the load.
EOP-005, System Restoration - Each Transmission Operator
shall have a restoration plan approved by its Reliability
Coordinator. The restoration plan shall allow for restoring the
Transmission Operator's System following a Disturbance in
which one or more areas of the Bulk Electric System (BES)
shuts down... Prior to energizing an area that has been
blacked out, the load must be isolated so that restoration
can proceed in a controlled manner where load is restored in
increments to stabilize frequency and voltage as the
restoration proceeds.
Question>> 3
If a real-time control center becomes non-operational for
whatever reason, the real-time system operators are
expected to .
continue to meet its functional obligations regarding the
reliable operations of the BES
notify its Regional Reliability Organization
read the Operating Plan for backup functionality for the first
time change to automatic control and evacuate
Answer>>
continue to meet its functional obligations regarding the
Page 2 of 63
,reliable operations of the BES.
Each Reliability Coordinator, Balancing Authority, and
Transmission Operator shall have a current Operating Plan
describing the way in which it continues to meet its
functional obligations regarding the reliable operations of
the BES in the event its primary control center functionality is
lost. - NERC Standard EOP-008
Question>> 4
Which of the following Dynamic Schedules must have a
modified tag?
The Dynamic Schedule is 200 MW and the hourly integrated
value is 230 MWH. The Dynamic Schedule is 100 MW and
the hourly integrated value is 120 MWH. The Dynamic
Schedule is 300 MW and the hourly integrated value is 320
MWH. The Dynamic Schedule is 275 MW and the hourly
integrated value is 300 MWH.
Answer>>
The Dynamic Schedule is 200 MW and the hourly integrated
value is 230 MWH.
NERC Standard INT-004 R2. The Purchasing-Selling Entity
that submits a Request for Interchange in accordance with
Requirement R1 shall ensure the Confirmed Interchange
associated with that Dynamic Schedule or Pseudo-Tie is
updated for future hours in order to support congestion
management procedures if any one of the following occurs:
2.1. For Confirmed Interchange greater than 250 MW for
the last hour, the actual hourly integrated energy deviates
from the Confirmed Interchange by more than 10% for that
hour and that deviation is expected to persist.
2.2. For Confirmed Interchange less than or equal to 250
Page 3 of 63
, MW for the last hour, the actual hourly integrated energy
deviates from the Confirmed Interchange by more than 25
MW for that hour and that deviation is expected to persist.
Question>> 5
A Transmission line is loaded at 125% of its System
Operating Limit. A parallel line is out for structure
maintenance and will take several hours to return to service.
Which of the following actions would be acceptable in these
conditions?
Open the overloaded line immediately.
Decrease the voltage setpoints on the generators in the area
Wait until the parallel line is restored. A 25% overload is
acceptable if the parallel line is returned by the end of the
day.
Re-dispatch generation to decrease loading on the line.
Answer>>
Re-dispatch generation to decrease loading on the line.
Re-dispatching generation would be first action to take if
available to try to unload the line.
Question>> 6
You are a Reliability Coordinator in area Z. You have issued a
Transmission Loading Relief procedure to relieve a
constrained flowgate on the contract path that includes the
Reliability Coordinator in area M where the Sink Balancing
Authority is located. You have notified all other Reliability
Coordinators via the Reliability Coordinator Information
System. The Sink Balancing Authority for the curtailed
Interchange Transaction should be notified by whom?
