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.
