Purpose
(1) Power generation
(2) Wind power generation is an important part of developing new energy and improving the environment
Significance
(1) Make full use of wind energy resources and reduce the consumption of conventional energy, which is in line with the direction of national energy reform. Moreover, wind energy is a renewable energy source (that is, the wind energy reaches its original value after a distance of 6 to 8 times the height of the wind wheel at the same location). Inexhaustible and inexhaustible. ?
(2) Compared with coal-fired power plants of the same scale, wind farms emit zero pollutants into the atmosphere, achieving zero solid and gas emissions. It has a positive effect on protecting the atmospheric environment. ?
(3) Wind farms can save a lot of fresh water resources and reduce water environment pollution compared with coal-fired power plants. It is especially important for coastal and arid areas that lack fresh water resources. ?
(4) Wind turbines are also a sight in coastal and tourist areas, which can reflect the degree of harmony between economy, culture and environment to a certain extent. ?
(5) Through physical education, the public’s awareness of developing natural resources and protecting the environment can be enhanced. ?
(6) The construction of wind farms is of great significance to the development of coastal economy. For example, building seafood cold storage, carrying out seawater desalination, and carrying out seasonal peak shaving of electricity all play a key role.
Wind turbines are electrical equipment that convert wind energy into mechanical work. The mechanical work drives the rotor to rotate and finally outputs alternating current. The working principle of the wind turbine is relatively simple. The wind wheel rotates under the action of wind. The kinetic energy of the wind is converted into the mechanical energy of the wind rotor shaft, and the generator rotates under the driving of the wind rotor shaft to generate electricity. It can also be said that a wind turbine is a thermal energy utilization generator that uses the sun as the heat source and the atmosphere as the working medium.
