The structure of electric power systems consists of the following terms:
1- Generating stations ( power station ) :
Bulk electric power is produced by special plants known as generating stations or power plants .
This part divided in two section :
a. Mechanical section: It is sources of mechanical energy as ( Boiler, Turbine….) .
b. Electrical section: As ( Alternators, transformers, protection apparatus, controls system, and measuring instruments….. ) .
2- Transmission lines:
Are the connecting links between the power stations and the distribution system and lead to other power systems over interconnections .
There are two types:
a. Overhead transmission line .
b. Under ground cables .
3- Distribution systems:
It connects all the individual loads to the transmission line.
Energy Resources:
The resources of electrical energy ( primary fuels ) may be divided into :
a. Thermal : as Coal, Oil, Natural gas, Nuclear, and Solar
b. Non Thermal : as Hydropower , Wind , and direct solar conversion .
While considering primary fuels in meeting the world’s energy requirements we may therefore include the following :
i- Solid fuels ( Coal )
ii- Liquid fuels ( Oil )
iii- Natural gas
iv- Hydropower
v- Nuclear
Location of power station:
The best geographical location of the generating plants would be close to the electrical load centers , i.e, the regions where the major energy demand exists . However, the locations of the primary fuel conventional energy sources do not necessarily
coincide with load centers.
We are therefore faced with following choice ;
1. Build the power plants close to the energy sources and then transport the electrical energy to the load centers
2. Build the power plants close to load centers and transport the
fuel from the source locality.
The electrical power grid makes the first alternative technically feasible . However, in reality , the actual choice will be based upon a combination of technical , economical and environmental factors.
Types of power station:
There are four type of power station :
1. Thermal power station ( Steam power station ), the primary fuels for this type are (oil or coal or natural gas )
2. Hydro-Electric power station , this type installed where resources of water available at sufficient head.
3. Nuclear power station , the primary fuels for this type is ( Nuclear fusion of Uranium )
4. Diesel power station , in this type , diesel engine is used as the prime mover.
