The Reliability Coordinator A) Increase Net Interchange Schedule by 20 MWs.
just informed you of a slow
time error correction which
will begin at the top of the
next hour. Your EMS system
will not let you change your
scheduled frequency. Your
Frequency Bias Setting is
-100 MW/.1Hz. What action
should you take?
A) Increase Net
Interchange Schedule by 20
MWs.
B) Inform the Reliability
Coordinator that you
cannot participate in the
time error correction.
C) Decrease Net
Interchange Schedule by 20
MWs.
D) Increase Net
Interchange Schedule by 10
MWs.
,A Balancing Authority has a C) 1 & 4
sudden loss of a large
block of load in its area. This
loss will be seen
instantaneously in the
change of which of the
following values?
1. Actual Net Interchange
2. Scheduled Frequency
3. Scheduled Net
Interchange
4. Area Control Error
A) 4 only
B) 1 & 3
C) 1 & 4
D) 3 & 4
Metered Data included in A) Tie lines readings
the calculation of ACE are:
dynamic schedules, pseudo
ties, actual frequency, and
all __________.
A) Tie lines readings
B) Generators output
C) Scheduled frequency
indications
D) Transformer load
,Balancing Authority A is A) -100
currently reading a system
frequency of 60.00 Hz. Its
Net Actual Interchange is
+100 MW and its Net
Scheduled Interchange is
+200 MW. If Balancing
Authority A's frequency bias
setting is 100 MW/0.1 Hz,
what is ACE?
A) -100
B) 0
C) 10
D) 100
A Balancing Authority has a B) 25 MWs in
Net Interchange Schedule
of -250 MWs from 1200 to
1600 on a summer day. The
Net Interchange Actual for
those same hours
respectively were -230 MW,
-275 MW, -250 MW and
-270 MW. What was the
Balancing Authority's
Inadvertent Interchange for
the 4-hour period?
A) 6 MWs out
B) 25 MWs in
C) 25 MWs out
D) 6 MWs in
, For the ACE equation to D) Tie lines
work properly, dynamic
schedules, pseudo ties,
frequency, and all
________________ must be
metered.
A) Generation
B) Communications
C) Transformers
D) Tie lines
If the frequency bias setting B) The ACE will be a negative value and AGC will
is set to a less negative increase generation
value than the frequency
response of a Balancing
Authority and a frequency
increase is caused by a
sudden loss of load in an
external balancing area,
what will be the result?
A) The ACE will be zero and
will take no AGC action
B) The ACE will be a
negative value and AGC will
increase generation
C) The ACE will be a
positive value and AGC will
lower generation
D)This will not affect the
ACE
