Answers 2023/2024
The purpose of a generator reactive capability curve is to show
what? - correct answer Thermal limits for excitation
When a long open ended transmission line is energized and the
leading chagrin current flowing through the lines inductance
crests a high voltage on the open end, this is known as what? -
correct answer Ferranti voltage rise effect
To maximize system stability, you would do which of the
following? - correct answer Operate the system at maximum
allowable voltage levels
The loading at which the line is VAR neutral, either generation or
consuming VARs is called - correct answer Surge impedance
loading
A shunt capacitor bank with nominal value of 60 MVARS is on a
bus with a voltage of .9 p.u. The actual VARS delivered by the
capacitor bank would be: - correct answer 48 MVAR
As a transmission operator, yo0u shall specify a voltage or
reactive power schedule at the interconnection between the
generator facility and the transmission owners facilities to be
maintained by each generator. You do so by: - correct answer
Providing the voltage or reactive power scheduled to the
associated generator operator and directing the generator
,operator to comply with the schedule in automatic voltage
control mod (AVR in service)
The transmission owner shall price which of the follow to the GO
(Required tap changes, a time frame for tap changes, technical
justification for tap changes) - correct answer All the above
The generator operator shall operate each generator connected
to the interconnected transmission system as follows unless the
generator operator has notified the transmission operator -
correct answer In the automatic voltage control mode
If a radial line is loaded at 100 MVA and is delivering 60 MVAR
to a load how many MW is it delivering to the load - correct
answer 80 MW
Generators operating to supply VARs to support voltage are
overexcited. This type of operation is also called - correct
answer Lagging
Generation which are underexcited are said to be absorbing
VARs to lower system voltage this type of operation is also called
- correct answer Leading
The terms leading and lagging refer to the relation of the
generators what with respect to voltage - correct answer
Current
Which of the following standards best measures a BA's ability to
carry adequate operating reserves - correct answer DCS
, If a reserve sharing group's largest single severe contingency is
a nuclear plant rated at 1200 MW and this nuclear plant is
uprated to 1300 MW through modifications, this reserve sharing
groups spinning reserved portion of fit contingency reserve must
increase from 600 MW to - correct answer 650 MW
The disturbance control standard requires the BA to reruthen
ace to zero withing what time period? - correct answer 15
minutes
The DCS compliance is what percentage of reportable
disturbances - correct answer 100%
The BA shall carry enough contingency reserved to handle -
correct answer The most severe single contingency
Which of the following does not count a s contingency reserves
( interruptible load, Fast start generation, Load shedding, static
VAR generators) - correct answer Static VAR Generators
Reportable disturbances are contingencies that are a greater
than or equal to what percentage of the most severe single single
contingency? - correct answer 80%
A BA or Reserve sharing group shall fully restore its contingency
reserves within the contingency reserve restoration period for its
interconnection. The contingency reserved restoration period
begins - correct answer At the end of the disturbance recovery
period
