UNIT OBJECTIVES
Upon completing this unit, you should be able to:
- Explain the basic operation of fossil fuel, hydroelectric, and nuclear
fission electrical power systems. - Define the terms “load (demand) factor” and “capacity factor” for
electrical power systems. - Describe coal, oil, and natural gas fossil fuel power production
systems. - Describe the functions of steam turbines, boilers, and other auxiliary
systems of power production systems. - Explain the difference between traditional hydroelectric systems
and pumped storage hydroelectric systems. - Describe load-demand control of modem electrical power
production systems. - List several alternative power production systems.
