Power Generation/Comparison
The previous Lesson was about variable loads on power stations. You are expected to remember the following from Lesson 7.
- Definitions
- Load Curves
- Types of loads on a power station
- Selecting generation units for a power station
- Base & Peak loads
- Methods of meeting load
Preview: Lesson 8
This lesson is about comparing of power stations. At the end of the lesson, you should understand how each power station discussed in this course measures up against others with respect to the following:
- Location & space required
- Initial & running cost
- Overal efficiency & stand-by losses
- Maintenance costs
- Limit of source of power
- Cost of fuel & clean emissions
- Starting
- Transmission & distribution costs
Five types of electric generating power stations have been discussed in this course thus far. These being:
There are other types of power stations used around the world besides the big five covered here. The following are not covered here due to the fact that they are strictly dependent on the geography of the area where they can be erected and hence do not find wide use around the world:
Note that the Pumped-storage scheme and Gas-turbine power stations are not included in this lesson as they are rarely used for base loads.
This lesson will compare the four widely used power stations (steam, hydro, diesel and nuclear) with regard to the following aspects:
- Location & space required
- Initial & running cost
- Overal efficiency & stand-by losses
- Maintenance costs
- Limit of power source
- Cost of Fuel & Clean emissions
- Starting
- Transmission & distribution costs
For the above comparison, sortable lists will be used with the following key of merit:
1 -- Highest merit (Highly desirable)
3 -- Second lowest merit (Tolerable)
2 -- Second highest merit (Acceptable)
4 -- Lowest merit (Not desirable)
You can click on the sorting icon to sort lists by the item you are interested in. This information is vital in deciding the type of power station that would be suitable in different situations.
