Do wind power plants emit radiation and affect people?

We sometimes see groups of windmill-like buildings in nature. These are wind power plants. Using wind energy to generate electricity is very environmentally friendly, and wind resources are abundant, so wind energy plays an important role in our lives. Wind power plants use clean and harmless wind resources. During the process of generating electricity, they do not produce radiation like nuclear power plants do, so they will not have any impact on the human body.

The principle of using wind energy to produce electricity is: the wind causes the blades of The windmill to rotate and the speed increases due to the increase in speed, thus converting the kinetic energy of the wind into mechanical energy, then theMechanical energy is converted into electrical energy, prompting the generator to produce electricity. The wind wheel of the windmill is an important part that converts the kinetic energy of the wind into mechanical energy, and the iron tower is an important structure that supports the wind wheel, rudder and generator. With wind turbines, even a breeze with a speed of just three meters per second can be harnessed to start producing electricity. The higher the wind force, the greater the kinetic energy of the wind and the greater the economic benefits generated by wind power plants. In the plateaus and coastal areas of northeast, northwest and southwest China, wind resources are particularly abundant. It is very significant and promising to develop wind power plants in these areas.

Wind power plants can be divided intofollowing types: The first type is a vertical axis wind turbine. The structural design of this generator is simpler than other generators. other conditions are certain, the power supplied by this generator is less; the second type is horizontal axis wind turbine, which can be divided into two types: doubly powered generators are more commonly used; It is also a doubly powered generator, which is increasingly used in wind power generation due to the development of electrical technology.

Wind power generation uses clean and renewable wind energy resources, which will not be depleted or pollute the environment. In addition, the construction period of wind power plants is short and it is not necessary to invest too much human and material resources. However, wind power plants also have their drawbacks. They must occupyer a large area of ​​land and, as they rely on natural wind resources, their electricity production is actually unstable and affected by natural conditions. During operation, wind power plants will also produce noise, which will affect the lives of surrounding residents to a certain extent.
