How many basic types of power plants are classified based on the energy used?
Answer: Depending on the energy used, there are the following basic types of power plants:
(1), Thermal Power Plants: Thermal power generation uses energy thermal obtained by burning fuels (coal, oil and derived products, natural gas, etc.) to produce electricity. There are two main forms of thermal power generation units: the boiler generates high temperature and high pressure steam to rotate the turbine and produce electricity, called a steam turbine generation unit, the fuel enters gas turbine to convert directly; 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 dominatedpowered by steam turbine generators.
(2) Hydroelectric power station: Hydroelectricity involves guiding river water (or lake water, river water) from high ground to downstream through 'a diversion to form a space to drive the rotation of the hydraulic turbine to drive the generator to produce electricity. A power plant that uses a hydroelectric generator to produce electricity is called a hydroelectric plant.
Hydroelectric power plants can be divided into:
① Run-of-river hydroelectric power plant: a reservoirless hydroelectric power plant that generates essentially as much water as it needs >
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 electricityricity;
③. Annual Regulating Hydroelectric Plant: A hydroelectric plant that optimizes the distribution and regulation of natural runoff each month of the year, stores excess water during wet periods in reservoirs and ensures the release of water for electricity production during dry periods. ;
④. Multi-year regulated hydropower plants: The uniform natural water flow over many years is optimally distributed and adjusted. The tank capacity adjusted for many years is larger. stored in the reservoir to supplement insufficient water during dry years to ensure the adjustable production of the power plant.
(3) Nuclear power plant: Nuclear power generation uses the thermal energy released by the slow fission of nuclear fuel (such as uranium) in the atomic reactor to generate steam (as a substitute of thea boiler in the thermal power station) to drive the steam turbine then drive the generator. The generator runs to produce electricity. Power plants that primarily produce nuclear energy are called nuclear power plants, or NPPs for short. According to 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: Using the wind to blow the large blades built at the top of the tower to rotate and drive the generator to produce electricity is called wind power generation. It consists of several, ten or. even dozens of wind power plants. An electricity production site made up of generators is called a wind farm.
(5). Others include geothermal power plants, the hundredtidal waves, solar power plants, etc.
