The common methods of electricity generation are mainly as follows: ① Thermal power generation uses thermal energy generated by the combustion of coal, oil, liquefied natural gas and other fuels to heat the water in the boiler water pipes so that it becomes high temperature and high temperature. pressurized steam, which turns the steam turbine and then drives the generator to produce electricity; ② Hydropower, by building a dam, the potential energy of water flowing from high places to low places is converted into kinetic energy. the hydraulic turbine installed in the lower part of the waterway is rotated by the water flow, combining the hydraulic turbine and power generation. The mechanical phase is connected to drive the rotation of the generator, converting mechanical energy into electrical energy. generation, such as the use of nuclear energy to heat the water in the reactor to generate steam, and driven by the steam, the steam turbine drives the rotation of the generator to generate electrical energy ④ Production wind power, using the wind drives the windmill to drive the generator to produce electricity; ⑤ Solar thermal power generation uses a heat collection device to collect solar thermal energy and heats the water in the water pipe to generate steam, which then drives the turbine generator to produce heat. electricity ⑥ Photovoltaic solar power generation uses silicon materials; with photoelectric effect. It is a solar panel that converts light energy into electrical energy by receiving sunlight. In addition, there are various power generation methods such as magnetic fluid power generation, la tidal power generation, ocean temperature difference energy production, wave energy production, geothermal energy production and biomass energy production. However, the current large-scale power generation methods are mainly thermal power generation, hydroelectric power generation and nuclear power generation.
The principle of Solar power generation is the use of radiant energy from the sun to generate electricity via water or other media and device systems converted into electrical energy. There are two basic ways to convert it into electrical energy. The first is that light converts the energy of solar radiation into thermal energy, that is, the production of solar thermal energy. Another method is to convert sunlight directly into electrical energy using devicesphotovoltaic, that is to say the production of solar energy.
There are two types of thermal energy production. One of these is solar thermal power generation, which uses reflectors to capture sunlight to heat water or other media, causing it to generate steam to power engines thermal turbines such as turbines, then drive generators to produce electricity. The other is to use the principles of direct thermoelectric conversion, such as thermoelectric (thermocouple) power generation, thermionic power generation, thermoelectronic power generation, magnetic fluid power generation, etc. , to directly convert accumulated solar heat into electrical energy.
