QUESTIONS WITH CORRECT DETAILED
ANSWERS || 100% GUARANTEED PASS
BRAND NEW VERSION
Time error correction -ANSWER✅✅✅✅60 +/- .02 Hz
ACE calculation frequency -ANSWER✅✅✅✅Every 6 seconds
CPS1 measures how well a BA controls its generation and load management programs
to support interconnection frequency over a ___ period. -ANSWER✅✅✅✅Rolling 1
year
A BA's BAAL cannot be exceeded for more than -ANSWER✅✅✅✅30 minutes
CPS1 minimum compliance level -ANSWER✅✅✅✅CPS1 >= 100% , which is
calculated and evaluated monthly
Contingency reserve requirements -ANSWER✅✅✅✅Contingency reserves must be
greater than or equal to the most severe single contingency (MSSC).
Balancing contingency event can include a series of events separated by ___ or less -
ANSWER✅✅✅✅1 minute
BAL-002: Reportable balancing contingency event -ANSWER✅✅✅✅Results in MW
loss described as:
80% of MSSC <= MW Loss <= MSSC
OR
>= 900 MW for East, 500 for West
contingency event recovery period -ANSWER✅✅✅✅15 minutes
, Must be returned to ACE value prior to event. Responsible entity is not subject to
compliance if it experiences multiple contingencies defined as a single balancing
contingency event, and the magnitude exceeds the MSSC
contingency reserve restoration period -ANSWER✅✅✅✅90 minutes
1% change in frequency results in -ANSWER✅✅✅✅3% change in motor load (2%
change in total load)
Typical tripping point for generators -ANSWER✅✅✅✅57 to 57.5 Hz
BAL-005: BA that is unable to calculate ACE for more than 30 min shall notify the RC
within ____ of the beginning of the inability to calculate ACE. -ANSWER✅✅✅✅45
minutes
BA's ACE calculation software must be available a minimum of ______ each year. -
ANSWER✅✅✅✅99.5%
BA's metering equipment used to calculate ACE must be available a minimum of _____
each year and be accurate within _______. -ANSWER✅✅✅✅99.95% , .001Hz
Reliability assessment period -ANSWER✅✅✅✅1 hour or less before ramp: 10
minutes to complete assessment
1 - 4 hours before ramp: 20 minutes to complete assessment
4 hours or more: 2 hours to complete assessment
VAR-002: the GOP shall notify the TOP of any status changes to AVR, power system
stabilizer, or alternative voltage controlling device within ____. -ANSWER✅✅✅✅30
minutes
If capability is restored within 30 minutes, the GOP is not required to notify.
VAR-002: The GOP shall notify the TOP of any change to reactive capability of a unit
within _____. -ANSWER✅✅✅✅30 minutes
If capability is restored within 30 minutes, the GOP is not required to notify.
When communications capability failure with required entities occurs and lasts more
than _____, COM-001 requires RCs, TOPs, and BAs to notify those entities within
______ of failure detection. -ANSWER✅✅✅✅30 minutes, 60 minutes
COM-001 requires each RC, TOP, and BA to test its alternative communication
capability at least ___________ -ANSWER✅✅✅✅Once each calendar month
