How many types of power plants are there? What are their functions?

Thermal power plant, hydroelectric power plant, nuclear power plant, wind power plant.

Thermal power plant: Thermal power generation is the heat energy obtained by burning fuels (coal, oil and its products, natural gas, etc.). ) to generate electricity. There are two main forms of generating sets for thermal power generation: using the high-temperature and high-pressure steam generated by the boiler to drive the turbine to rotate and drive the generator to generate electricity, which is called a steam turbine generating set; Fuel enters the gas turbine, directly converts heat energy into mechanical energy, and drives the generator to generate electricity, which is called gas turbine generator set. Thermal power plant usually refers to a power plant with steam turbine generator set as the main part.

Hydroelectric power plant: Hydroelectric power generation refers to leading higher river water (or lake water or river water) downstream to form a gap to drive the turbine to rotate and drive the generator to generate electricity. A power plant that generates electricity by a hydro-generator set is called a hydropower plant.

Nuclear power plant: nuclear power generation is to use the heat energy released by the slow fission of nuclear fuel (such as uranium) in atomic reactors to generate steam (instead of boilers in thermal power plants) to drive the steam turbine, and then drive the generator to rotate to generate electricity. Power plants that generate electricity mainly by nuclear energy are called nuclear power plants.

Wind farm: Wind farms are called wind farms, and wind farms consisting of several, dozens or even dozens of wind turbines are called wind farms.

The role of power plants:

The function of a power plant is to convert all kinds of energy into electric energy by chemical and physical means. For example, coal, oil and natural gas are converted into electric energy by chemical means; And convert solar energy, wind energy, etc. Converted into electrical energy by physical means. When electric energy is sent to every household through lines, it can be converted into heat energy, light energy, kinetic energy and so on.
