Power plants are divided into the following basic types based on the energy used:
(1) Thermal power plant: Thermal energy is obtained by burning fuel (coal, oil and its products, natural gas, etc.) Thermal energy produces electricity. There are two main forms of thermal power generation units: the boiler generates steam at high temperature and high pressure to drive the rotation of the steam turbine to drive the generator to produce electricity, called steam turbine generating unit into which fuel enters; gas turbine to directly convert thermal energy into mechanical energy to drive the generator to produce electricity, called gas turbine power generation unit. Thermal power plants generally refer to power plants dominated by steam turbine generators.
(2) Hydroelectric power station : hydropower involves guiding river water (or lake water, river water) from high ground downstream through a diversion to form a space that drives the turbine to rotate and causes the generator to produce electricity. A power plant that uses a hydroelectric generator to produce electricity is called a hydroelectric power plant.
Hydroelectric power plants can be divided into:
① Run-of-river hydroelectric power plants: Without reservoirs, hydroelectric power plants essentially generate as much electricity as they need from water; >
②.Daily regulated hydroelectric power station: The reservoir is very small, and the regulation cycle of the reservoir is one day and one night. A hydroelectric plant that regulates natural runoff through the reservoir to produce electricity throughout the day and night. ;
③. Hyd plantannually regulated roelectric: This is a hydroelectric power plant that optimizes the distribution and regulation of natural runoff from each month of the year, stores excess water during wet periods in reservoirs and ensures the release of water for electricity production in dry periods.
Answer: Depending on the energy used, power plants have the following basic types: (1) Thermal Power Plants: Thermal power generation uses thermal energy obtained by burning fuel (coal, oil and derived products, gas, etc.) Produce electricity. There are two main forms of thermal power generation units: the boiler generates steam at high temperature and high pressure to drive the rotation of the steam turbine to drive the generator to produce electricity, called steam turbine generating unit into which fuel enters; the gas turbine for convDirectly convert thermal energy into mechanical energy to drive the generator to produce electricity, called gas turbine power generation unit. Thermal power plants generally refer to power plants dominated by steam turbine generators. (2) Hydroelectric power station: Hydropower is to guide river water (or lake water, river water) from high ground to downstream through diversion to form a space which drives the turbine to rotate and drives the generator to produce electricity. A power plant that uses a hydroelectric generator to produce electricity is called a hydroelectric power plant. Hydropower plants can be divided into: ①, run-of-river hydropower plants according to the regulation performance of the reservoir: ①, run-of-river hydropower plants: there is no reservoir and mainly generateas much electricity as the quantity of water; ②, daily regulated hydroelectric power stations: the reservoir is very small and the reservoir regulation cycle is A hydroelectric power station that regulates natural runoff throughout the day and night through a reservoir to produce electricity ③ Hydroelectric power station with annual regulation: optimizes distribution and; regulating natural runoff each month of the year, stores excess water in the reservoir during the wet season and ensures the release of water during the dry season Hydroelectric power plants that produce electricity ④ Multi-year regulated hydroelectric power plants : Optimize distribution; and regulation of uneven natural water supplies over many years. Reservoirs with multi-year regulation have a greater capacity. Excess water from wet years is stored in the reservoir to supplement dry years. The quantity ofau is insufficient to ensure adjustment. production of the power plant. (3) Nuclear power plant: Nuclear power generation uses thermal energy released by the slow fission of nuclear fuel (such as uranium) in an atomic reactor to produce steam (replacing the fire boiler of the power plant drives the steam turbine, then drives the generator to spin and produce electricity Power plants that primarily produce nuclear power are called nuclear power plants, or NPPs for short depending on the type of nuclear reactor. , nuclear power plants can be divided into pressurized water reactor, boiling water reactor, gas-cooled reactor, heavy water reactor, fast breeder reactor, etc. (4) Wind farm: The use of wind to blow large ones. blades built at the top of the tower to rotate and drive the generator in order toproducing electricity is called wind power generation. An electricity production site made up of several, tens, or even dozens of. Wind turbines are called wind farms. (5) Others include geothermal power plants, tidal power plants, solar power plants, etc.
