1. Why are tie-lines an important aspect of power production? ANS >>>
Alternating current used in homes and businesses cannot be stored in batteries for
future use. It has to be supplied when needed.
2. True or False Generators are machines that convert mechanical energy to
electrical energy. ANS >>> True
3. The electricity that a power plant produces is measured in ANS >>> Watts
mailto:https://www.stuvia.com/en-us/user/techgrades
, 4. How many watts are in a megawatt? ANS >>> 1,000,000
5. What does a substation do? ANS >>> Combines electric power from multiple
sources together in one location
6. One power company is often connected to another power company by ANS
>>> ANS >>> -
Tie-lines
7. What does a load dispatcher of resource coordinator do? ANS >>> Predicts
demand, monitors condition of the power system, coordinates the output of the
power plants so that supply always equal demand
8. The of power must always equal the for power. ANS >>>
Supply and demand
9. A hydroelectric plant uses mechanical energy from to turn a genera-
tor ANS >>> Water
10. List the three components of a fossil fuel plant where energy conversions
take place. ANS >>> Boiler, Turbine, Generator
mailto:https://www.stuvia.com/en-us/user/techgrades
, 11. True or False ANS >>> In a fossil fuel plant, pressure and thermal energy in
steam are converted to mechanical energy in a turbine. ANS >>> True
12. Where is the thermal energy made? ANS >>> Boiler
13. Two disadvantages of fossil fuel plants ANS >>> Cost of fuel and more
complicated
14. What are three advantages of fossil fuel plants? ANS >>> Location flexibility,
Can be sized for desired output, not rain dependent
15. Where is the steam produced? ANS >>> Waterwalls
16. What fans provide the secondary air? ANS >>> FD fans
17. What is the function of secondary air? ANS >>> Providing enough air to
support combustion
18. A combination of pipes and equipment connected together to perform a
function is called a . ANS >>> System
19. List two things that a boiler in a plant does ANS >>> ANS >>> 1. Burns fuel to

, produce heat
2. Uses heat to convert water to steam
20. For proper combustion to take place, the boiler needs a continuous supply
of and . ANS >>> Fuel and air
21. In a typical coal burning plant, coal is transported to a plant by a conveyor
system and then fed into a , where it is ground into a fine powder.
ANS >>> - Pulverizer
