Electricity generation methods include: thermal power generation, hydroelectric power generation, nuclear power generation, wind power generation, geothermal power generation, etc.
Power generation refers to the production process of using power generation devices to convert raw energy such as water energy, thermal energy from petrochemical fuels (coal, oil, natural gas), nuclear energy, etc. .in electrical energy.
Electricity generation is used to meet the needs of various departments of the national economy and people's lives.
Nowadays, fossil fuels are still used as the main form of electricity generation, but fossil fuel resources are not plentiful and are becoming increasingly depleted. Human beings have graduallystarted using solar energy, wind energy and geothermal energy. , ocean energy and other energy sources to generate electricity.
Hydropower uses the mechanical energy of flowing water to produce electricity. The flowing water drives the turbine, causing the generator's magnetic windings to rotate, producing a changing magnetic field which then induces current in the surrounding coil windings, so that the generator emits electricity.
In order to obtain a greater flow of energy to push the turbine, the water flow acting on the turbine must have greater potential energy. The faster the water flow and the greater the head, the greater the potential energy of the water flow and the greater the kinetic energy obtained by converting the potential energy by the turbine.
People can use the difference in hauthor of natural rivers or waterfalls to produce electricity. However, there are not many rivers or waterfalls with large drops on the earth, and the river water is divided into flood period and dry water period, so it is impossible to obtain a stable electricity production.
Therefore, people use artificial methods to increase the fall and speed of water flow, that is, to build embankments in the narrowest sections of the river, to dam the river and store the water, so that the river water can flow out of the high embankment. It pours from above and drives the turbine to produce electricity. For example, the aforementioned Three Gorges, Gezhouba and Xiaolangdi are all large hydroelectric power stations. Additionally, on small rivers in some mountainous areas, small hydroelectric power stations equipped with small turbines can be used.nstructed to solve the problem of electricity consumption of dispersed populations. Compared with other electricity generation methods, hydropower has the characteristics of low cost, low pollution and low electricity price.
