Subject to availability. A single wind turbine should be at least 200m away from residential areas, and for large wind farms, this minimum distance should be no less than 500 meters to prevent the human body from being affected by electromagnetic wave radiation from wind power. Converting the kinetic energy of the wind into mechanical kinetic energy, and then converting the mechanical energy into electrical kinetic energy, is wind power generation. The principle of wind power generation is to use wind power to drive the windmill blades to rotate, and then use a speed increaser to increase the speed of rotation to prompt the generator to generate electricity.

No
1. The power frequency is 50Hz, which means the electromagnetic speed should reach 3000 rpm.
2. Electromagnetic speed = mechanical speed * pole number. Therefore, mechanical speed = 3000/P. Generally speaking, P = 4~8. The larger the number of pole pairs, the larger the outer diameter of the generator, so the number of pole pairs of 8 should be relatively large.
3. Taking p=4 pair as an example, the wind turbine speed is basically 750 rpm.
4. The generator speed of wind power generation is proportional to the wind turbine speed. The proportion depends on the gear ratio of the gearbox. Do not equate the wind wheel speed with the motor speed.
