Of course wind turbines emit radiation, and all objects in the world emit radiation, because no object can reach absolute zero. Radiation occurs everywhere in nature, and proper design will not have any impact.
The noise pollution mainly produced by the fans cannot be judged whether it exceeds the standard due to different environments. You can ask the environmental protection department or a third-party testing agency at your own expense to test the noise intensity to see if it meets the national standards.
Generator principle:
The principle of wind power generation is to use wind power to drive the windmill blades to rotate, and then increase the speed of rotation through a speed increaser. to cause the generator to generate electricity. According to current wind turbine technology, power generation can start at a breeze speed of about three meters per second (the level of breeze).
It is an electrical device that converts wind energy into mechanical energy and mechanical energy into electrical energy. Broadly speaking, it is a heat energy utilization engine that uses the sun as the heat source and the atmosphere as the working medium. Wind power uses natural energy. It is much better than diesel power generation. But if it is used in an emergency, it is still not as good as a diesel generator. Wind power is not considered a backup power source, but it can be used for the long term.
The impact of wind power on the climate and environment is as follows:
1. The impact of wind power on the environment
Wind power affects local climate. Wind power uses wind energy in the atmosphere. According to the law of conservation of energy, the consumption and production of one kind of energy must produce or consume another kind of energy. Therefore, wind power The power generation process of the generator set must consume part of the wind energy in the atmosphere. As one of the important factors of climate change, wind energy changes will inevitably bring about climate changes.
When some offshore wind farms and inland ridge wind farms are operating, if the humidity is relatively high, a huge water vapor tail will condense behind the wind turbine, which may affect the local microclimate, such as humidity, sand and dust. Subsidence has an impact.
Accidents are likely to occur when the wind turbine blades are damaged. When the wind turbine blades are subjected to strong winds above 25m/s (cut-out wind speed), although the wind turbine is in a shutdown state, due to The bending moment, torque, shear strength, and extrusion strength that the blade root can withstand is limited. In severe cases, the entire blade can fly out.
Causing casualties and building damage on the road (although wind turbines are mostly located in coastal areas with sparsely populated areas). In addition to extreme winds, blade surface corrosion, lightning strikes, ice coating, cracks, etc. can easily cause blades to break, causing accidents and affecting public safety.
2. The impact of wind power on climate
It is mainly reflected in reducing greenhouse gas emissions and affecting the distribution of wind; the impact on the environment is mainly reflected in the occupation of Land, noise pollution and impact on wildlife.
Wind power uses wind energy to generate electricity, which has many advantages, such as environmental protection, renewable, low cost, etc. However, wind power also has some problems, such as its impact on the environment and wildlife, so we should develop wind power while , taking a series of measures to reduce the impact on the environment and wildlife to achieve sustainable development.
3. Hazards of wind power generation
Wind power generation will harm the local ecological environment, such as destroying vegetation, changing the topography, causing soil erosion and desertification of the land. . The electromagnetic radiation produced by wind power affects human habitation. An alternating electromagnetic radiation field is formed around high-voltage transmission lines and affects human health.
Wind power affects local climate. Wind power uses wind energy in the atmosphere. The power generation process of wind turbines consumes part of the wind energy in the atmosphere and brings about climate changes.
