QUESTIONS AND CORRECT DETAILED
ANSWERS 100%CORRECT
Operating reserves are that capability above firm system demand required to provide for
regulation, load forecasting error, equipment forced and scheduled outages and local area
protection. It consists of spinning and non-spinning reserve. If an hourly load forecast greatly
underestimate the load, a shortfall of available generation to cover load and reserves is likely
due to not committing enough generation for the day. The instantaneous loss of generation,
cutting Interchange Scheduled purchases and de-rating generators are covered within the
reserve requirement. If reserves are needed to cover load, then the BA is not meeting load and
reserves requirements.
Early in the day, a BA with several units offline anticipates a capacity shortage during the
afternoon. What should the BA consider first? - ANSWER>>Postpone or cancel unit
maintenance where practical
If firm Load shed is imminent or in progress, what level Energy Emergency Alert is required? -
ANSWER>>EEA 3
A Balancing Authority informs the Reliability Coordinator that the projected load in a Balancing
Area for the next four hours (over the morning peak) is trending above the available generation
that had been committed for the day. Operating Reserves will be required to be converted into
energy to cover the shortfall. Which Energy Emergency Alert (EEA) level should the RC declare?
- ANSWER>>EEA 1
What is the role of a Reliability Coordinator during system restoration? -
ANSWER>>Coordination between the transmission operators restoration plan
Which type of emergency condition is due to not being able to meet the load requirements of
an entities retail customers? - ANSWER>>Energy Emergency
How often should the Transmission Operator and Balancing Authority review and update their
Loss of Control Room Functionality Operating Plan? - ANSWER>>Annually
, Which of the following best describes the Load/Frequency Relationship? - ANSWER>>Load
magnitude varies with system frequency
A system operator notices that frequency has dropped to 59.95 Hz, but his Balancing Areas ACE
is zero. The Balancing Authority has plenty of generation and helps the Interconnection by
requesting his generators to increase additional MW. Which statement best describes the
impact of his action? - ANSWER>>Increasing generation unilaterally may cause transmission line
over-loading
All Balancing Authority Areas have provided frequency response by increasing their generation
slightly. A Balancing Authority shall not unilaterally adjust generation in an attempt to return
Interconnection frequency to normal beyond that supplied through frequency bias action and
Interchange Scheduled changes. Increasing generation without coordination may overload
transmission facilities.
As a Transmission Operator, you realize that the voltage level is starting to decline in the North
West part of the system. Which of the following devices should you, as a Transmission
Operator, be able to operate, and/or have another entity operate to raise the voltage level back
to normal in the North West part of the system? - ANSWER>>Transformer Underload Tap
Changers, Shunt Capacitor Banks, and Generator Reactive are correct
Voltage reduction for load relief should be made on the . - ANSWER>>Distribution
system
Normally, voltage reduction for load relief should be made on the distribution system. Voltage
reduction on the sub transmission or transmission system may be effective in reducing load;
however, voltage reduction should not be made on the transmission system unless the system
has been isolated from the Interconnection. This is because implementing a voltage reduction
on a single system that is still interconnected to its neighbors will have a negative impact on the
voltage of neighboring systems as MVAr move from the neighboring systems to the system
attempting to reduce its voltage. - NERC Standard TOP-001
A Balancing Authority anticipating an operating capacity or energy emergency shall perform all
actions necessary including - ANSWER>>Bringing on all available generation and being prepared
to reduce firm load
