Questions and CORRECT Answers
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
