following will increase this voltage?
a) Switch off the distribution circuit capacitors
b) Raise the generation supply at the remote end
c) Raise the stepdown transformer tap position
d) Switch additional load to this circuit - correct-answer -C
When synchronizing isolated areas, which of the following conditions must be
met (3 choices to pick)?
1. Similar frequency
,2|Page
2. Similar voltage
3. Matching load
4. Minimum phase angle difference - correct-answer -1, 2, and 4 only
A real time security analysis contingency or actual overload is

answer -D
A 1000 MW generating unit is located in an area with three transmission lines
carrying power from the generation source to the customer load. Each line has an
emergency limit of 400 MW. The maximum pre-contingency load that the
generator should be allowed to load is:
,3|Page
a) 200 MW
b) 600 MW
c) 800 MW
d) 1000 MW - correct-answer -C
Distribution factors are used to determine:
a) The distribution of voltage levels on key lines
b) The surge impedance loading of lines
c) The impact of placing capacitor banks in or out of service
d) How the flow of MW on a line will be redistributed upon its loss - correct-
answer -D
PJM has issued a heavy load voltage schedule. Which of the following is NOT an
appropriate PJM member action in response to this alert?
a) Ensure that all unit voltage regulators are in service
, 4|Page
b) Ensure that all unit voltage regulators are in manual mode
c) Ensure that all reactors are out of service and available capacitors are in service
d) Ensure that all units connected to the 500 kV system are operated so that
reasonable MVAR reserve is maintained - correct-answer -B
Which of the following reasons describes why opening a pre-studied EHV line has
a positive effect in reducing system voltages?
1. Eliminates the capacitance charging of the line
2. Increases MW flow on other EHV lines, thereby reducing their MVAR output
3. Eliminates circulating VARs on transformers
4. Helps increase reactive import capability a) 1 and 2 only b) 1 and 3 only c) 2 and
4 only d) 3 and 4 only - correct-answer -A
During system restoration, an island requires 400 MW of dynamic reserve. The
maximum load allowed with underfrequency relay protection enabled that can be
counted as dynamic reserve is:
