Electric Power Plants A power station is an industrial facility for the generation of electric power.
ď Ż Conventional Power Plants ď Ż Non-Conventional Power Plants
Conventional Power Plants Thermal Power Plants Combined Cycle Power Plants Nuclear power plants Hydroelectric Power Plants
Thermal Power Plants ď Ż Water is heated in a boiler by the heat,
the steam that is generated moves the turbine connected to the generator.
Combined cycle power plants ď Ż They obtain electricity as the result of
two combined cycles: a cycle that uses air and gas, and a conventional thermal cycle.
Nuclear Power Plants ď Ż They use a nuclear fission reactor that
produces heat to generate the pressurised steam needed to move the turbine rotor.
Hydroelectric Power Plants ď Ż The energy of the height of the water
moves the blades of the turbine. There are two types: Gravity and Pump
Non-conventional Power Plants Wind turbine Solar power plants Biomass thermal power plants Geothermal power plants Ocean power plants
Wind turbine ď Ż Use the kinetic energy of the wind to
move the blades of a rotor at the top of a tower.
Solar Power Plants ď Ż Use the Sun’s energy. There are two
types: Photo-thermal power plants and Photovoltaic power plants.
Biomass Thermal Power Plants ď Ż They are thermal power plants that use
biomass as a fuel.
Geothermal Power Plants ď Ż Use the heat found at deep layers in the
Earth.
Ocean power plants ď Ż Use the energy from the oceans and seas:
Tides, waves or thermal gradient.
