Small wind turbine electric energy energy


It refers to the production process of converting hydropower, fossil fuel (coal, oil, natural gas) thermal energy, nuclear energy, solar energy, wind energy, geothermal energy, ocean energy, etc. into electrical energy by using power generation power devices, called power generation. Used to supply the needs of various sectors of the national economy and people’s lives. Power generation devices are classified into thermal power installations, hydropower devices, nuclear power devices and other energy power generation devices according to the type of energy. Thermal power plant consists of power plant boilers, steam turbines, generators (usually called the three main engines) and their auxiliary devices. The hydroelectric power plant consists of a water turbine generator set, a governor, a hydraulic device and other auxiliary devices. The nuclear power plant consists of a nuclear reactor, a steam generator, a steam turbine generator set and other auxiliary equipment. Electric energy is easier to regulate than other energy sources in the production, transmission and use. Therefore, it is an ideal secondary energy source. Power generation is at the center of the power industry, which determines the scale of the power industry and also affects the development of transmission, transformation, and distribution in the power system. By the end of the 1980s, the main forms of power generation were thermal power generation, hydropower generation and nuclear power generation, and the three generations accounted for more than 99% of the total power generation. Due to the impact of coal, oil, natural gas resources and environmental pollution, the proportion of thermal power generation in the world fell from about 70% to about 64% in the 1980s; hydropower has been nearly developed due to industrially developed water resources. 90%, so the proportion is maintained at about 20%; the proportion of nuclear power generation is on the rise, and by the end of 1980, it had exceeded 15%. This reflects that with the shortage of fossil fuels, nuclear power will be paid more and more attention.
