Thermal energy production uses thermal energy 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 dominated by steam turbine generators.
Thermal power plants are mainly composed of four key elements, namely boilers, steam turbines, condensers and generators. Fuel combustionant converts chemical energy into thermal energy to heat the boiler water into steam, then the thermal energy of the steam drives the steam turbine to do work, converting the thermal energy into mechanical energy, then the Mechanical energy is converted into electrical energy through the generator, thus completing the entire process of electricity generation. Hydropower generation is the process of guiding high altitude river water, lake water or river water downstream through diversion to form a space that rotates the turbine and drives 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:
①Trickle hydroelectric power plant: there is no reservoir and generatesessentially as much electricity as water goes in;
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 power plant that regulates natural runoff through the reservoir to produce electricity throughout the day and night
< p> ③ Annually regulated hydroelectric power plant: It regulates power in a year. The natural runoff of each month is distributed and adjusted optimally, and excess water during the rainy season is stored in the reservoir to ensure the release of water for electricity generation during the dry season.④ Multi-year regulated hydroelectric plant: optimizes the distribution and regulation of uneven natural water supply over many years. The reservoir with multi-year regulation has a greater capacity. Excess water from wet years is stocked. into the tank to supplement the dry water. There is not enough water in the year to ensure the adjustable output of the plant. For example, geothermal power plants, tidal power plants, solar power plants, etc.
