Wind turbines are very noisy and very disturbing. What can be done effectively?
There are two types of noise produced by wind turbines. One is the noise generated by the generator transmission chain in the unit cabin. , and the other is the rotation of the blades produced by air currents.
Nowadays, the height of wind turbine towers is generally greater than 80 meters. From my personal experience in the wind farm, the noise of the generator transmission chain in the cabin is very low, even inaudible under the unit. . The loudest sound is that of the blades.
If it is just the ordinary sound of blades sweeping in the wind, there is no way to fix this problem. However, some blades have problems or are broken, and the blades whistle. This is a fault point that can be resolved by repairing or replacing the blades.
In addition, when the cabin rotates, certain malfunctionsof the unit emit a loud yaw noise. This can be solved by repairing and replacing the yaw pad or friction plate and other parts. the unit. .
Of course, regardless of the above, you can complain if the noise generated disturbs residents. The project must pass an environmental assessment before construction, and the environmental assessment includes noise. Report noise complaints to the relevant environmental departments. These services will go to the wind farm to inspect or supervise, and they will at least resolve the problem, such as repairing broken units in a timely manner.
This should be the sound made when yawing. If the yaw ring gear and yaw motor gear are not meshed well, a loud noise will be emitted. The yaw rate is very slow, so it is normal for the noise to last for two or three minutes. The fan will not make any particular noise when connected to the networkon or off the network, except that the sound of the contactor is louder and instantaneous. The sound of the blades is not so loud that it can be heard a kilometer or two away.
