NERC Test Questions and Answers
Graded A+
What percentage of load gives a 1 Hz change in an island condition? - Correct
answer-6-10% (Think 6-10 day island vacation)
If ACE is Zero but system Hz is off, what should a system operator do? - Correct
answer-Nothing! ACE bias and interchange schedule will improve frequency
If ACE is Zero, why not adjust generation to help frequency? - Correct answer-
Could overload equipment, this is a NERC violation
When restoring from blackout condition, what should be done with load? - Correct
answer-All load breakers should be opened, load should be restored in a controlled
manner not to exceed 5% of current available gen
What's the point of COM-001? - Correct answer-Each TO, BA, RC and NERCNet
Use Orgs need to have good comms
Where do they need to have comms? - Correct answer-Internal, Between RC, TO
and BA, Other RC, TO, BA and authorities
,Where applicable comms should be ______ and _______ routed. - Correct answer-
Redundant and Diversely routed, just in case something fails
How do we know comms will be good? - Correct answer-They will manage, alarm,
test and/or actively monitor, especially emergency comm facilities and equipment
(non-routine equipment)
When can languages other than English be used? - Correct answer-Only for
internal operation, Operation of the BES requires comms in English
What is required so operation during a loss of comms will be ensured? - Correct
answer-Written operating instructions and procedures
What is the point of COM-002? - Correct answer-Ensure BA, TO, GO, and RC
have comms and capability to use them for addressing emergency and that
operators are trained to use them
Who should a BA or TO notify if they are aware of any condition that could
threaten area reliability or when shedding load? - Correct answer-Notify their RC
and any other potentially affected BA or TO
How should directives be issued by an RC, TO or BA? - Correct answer-In a clear,
concise and definitive manner, using 3 part(way) communications
,Who is required to create a blackstart restoration plan? Who approves it? - Correct
answer-Transmission Operators; Its RC
When is the blackstart condition finished? - Correct answer-When the choice of the
next load to be restored is not driven by frequency and voltage control
Who directs the procedure for restoring interconnection between Tos? - Correct
answer-RC
What must be done prior to implementing changes in a restoration plan? - Correct
answer-The parties invloved must be told of changes to their role and specific tasks
prior to implementation.
How often must the plan be confirmed given no changes were made? - Correct
answer-TO annually review the plan and report to RC
After a system modification is made, how long does the TO have to update
restoration plans? - Correct answer-90 days
Where is a copy of the restoration plan required to be kept? - Correct answer-Main
and backup control rooms
What must be done on the restoration plan every five years? - Correct answer-
Analyze the plan through actual events, steady state and dynamic simulations or
testing that the plan can work as intended.
, How often must a Blackstart Resource verify it can meet real and reactive power
requirements of its cranking path and intial load? - Correct answer-Every 5 years
How often must the location of loads required to control voltage and Hz in a
blackstart be verified within operating limits? - Correct answer-Every 5 years
How often is the capability of generating resources required to control voltage and
Hz in a blackstart condition verified? - Correct answer-Every 5 years
What should a TO use if the restoration plan cannot be executed? - Correct answer-
Use its restoration strategies
Under what conditions can a TO resynchronize with its neighboring TO? - Correct
answer-Only with RC approval or with the established procedures of the RC
What is the point of Blackstart Resource testing? - Correct answer-To ensure the
resource is capable of me4eting the requirements of the restoration plan
How often must a Blackstart Resource be verified at a minimum? - Correct
answer-Once every 3 years
Name two requirements when testing a Blackstart Resource: - Correct answer-
Ability to start with no BES support and remain energized without the rest of the
system; The ability to energize a bus
