ALL TEST BANK- QUESTIONS AND CORRECT
DETAILED ANSWERS WELL VERIFIED .GRADED
A+
A transmission line loaded above its surge impedance loading is (a): -
ANSWER -Net user of Mvar from the system
Which of the following actions is used to prevent a voltage collapse
(due to a reactive power deficiency)? - ANSWER -Implement load
reduction
In what manner is voltage reduction typically implemented to obtain
load relief? - ANSWER -. Changing transformer taps
,Your system is experiencing severe low voltages along its southern
interface with a large interconnected system. The systems to the south
are absorbing large amounts of reactive power into their systems, which
is causing your low voltage problems. You have tried all possible
generation adjustments, reactive switching, etc., to solve the low
voltage condition. After communicating with your southern neighbors,
your next option would be: - ANSWER -Separate from the southern
systems to preserve your own system
If a capacitor bank is removed from service, what immediate effect will
there be on the voltage? - ANSWER -Decrease
Generators have the ability to be used as voltage control devices. If a
generator raises its Var output, the system operator should expect the
system voltage to: - ANSWER -Increase
Who is responsible to know the status of all transmission reactive
power resources, including the status of generator automatic voltage
regulators and power system stabilizers? - ANSWER -The Transmission
Operator
Following a contingency or other event that results in an IROL violation,
the appropriate Transmission Operator shall return its transmission
, system to within limits as soon as possible, but no longer than: -
ANSWER -30 minutes
If a transmission loading condition is deemed critical to bulk system
reliability by a Reliability Coordinator, the Reliability Coordinator has the
authority to immediately direct Balancing Authorities and/or
Transmission Operators to do all of the following except: - ANSWER -.
Reduce load in a different Reliability Area
Transmission line removal as a voltage control tool can be used if: -
ANSWER -Reliability stays at acceptable limits
A Transmission Service Provider has studied their system and
determined that its ATC is 1000 MW from area A to area B. Assume that
this Transmission Service Provider sells 500 MW of this ATC as non-firm.
No other ATC is sold. What amount of firm ATC does this Transmission
Service Provider have from area A to B after this 500 MW non-firm sale
is completed? - ANSWER -1000 MW
A __________ tool is used to ensure the power system can respond
within acceptable limits to N-1 conditions. - ANSWER -Contingency
analysis
