1. Wind power was stopped because its environmental damage was far greater than the economic benefits it produced, and it was even less respectful of the environment. The damages include:
2. Wind power generation will harm the local ecological environment, destroy vegetation, change topography, cause soil erosion, and desertify land.
3. Electromagnetic radiation produced by wind power generation affects human habitation. In wind power generation systems, generators, substations, transmission lines, etc. are the main causes of electromagnetic radiation. When the receiving device attached to the wind power plant receives the signal, it will receive the electromagnetic wave signal reflected from the wind turbine blades. Reflected signals are delayed signals that can have an impactt significant on AM radio systems.
4. Wind energy affects the local climate. Wind energy uses wind energy present in the atmosphere. According to the law of conservation of energy, the consumption and production of one type of heat must produce or consume another type of energy. Therefore, the energy production process of wind turbines must consume some of it. Wind energy in the atmosphere, and wind energy is climate change. One of the important factors of change, its changes will inevitably lead to climate change.
5. Wind power blades are prone to safety accidents when the wind turbine blades are subjected to strong winds of more than 25 m/s, although the wind turbine is in a stopped state, due to the bending moment. and Torque, shear strength and extrusion resistance are limited. In severe cases, the entire blade mayfly away, causing casualties and damage to buildings on the road.
6. Noise hazards caused by wind power generation For a wind turbine of such size, when the long blades rotate, noise is inevitable. Wind blade noise can be roughly divided into three categories: Thickness noise, which is produced by the compression of the air and the blades. In windy weather, when doors and windows are closed, you often hear a sharp, harsh sound, which occurs. it feels like a ghost is crying or a wolf is howling? , coupled with the dark sky outside, it's a bit scary to think about it; load noise, as its name suggests, is caused by the blades supporting a large load; the Mach number is close to 1. In this way, the impact of noise on the environment cannot be ignored.
Will the wind turbine turn in the direction of the wind
It's possible, but it won't be asi stable. The output voltage will change with the wind. . When the wind is strong, the voltage is high, the wind is weak and the voltage is low. If the electrical appliances used do not have high voltage requirements, it is d, but for electrical appliances with high voltage requirements (such as). like computers and other electrical appliances), it is not possible, so if you always use it, it will damage the use of electrical appliances. You need to pay attention to this!
Answer to your additional questions: First of all, the principle of voltage and current stabilization is that voltage stabilization can only be achieved when the power supply is large enough! When the power generated by wind energy is not sufficient (the wind is weak), the voltage cannot be stabilized! The stability of wind energy production is not so continuous! Even if a saypositive voltage and flow stabilization is added, the effect is still not satisfactory! The best solution is to stabilize the voltage and current of the intermediate link of the battery, so don't worry about it. It's better to let it go! It can be used when wind power is insufficient (when the wind is weak), and the insufficient power can be temporarily supplied by the battery.
I don't feel the wind when I stand at the 'floor. How to use it. wind energy
Yes, the cabin can rotate and is always facing the wind. The technical term is yaw. Of course, the pod will not always rotate in one direction, such as clockwise or counterclockwise. If the wind direction is unlucky, it will always move in the same direction. The fan will rotate at most seven to eight hundred degrees. must also be actively running, whichthis is called unmooring. Prevent the cables inside from being pulled out.
A wind turbine is an electrical device that converts wind energy into mechanical work, which causes the rotor to rotate and ultimately produces alternating current. Wind turbines generally consist of components such as a wind wheel, a generator (including devices), a steering (tail), a tower, a speed-limiting safety mechanism, and an energy storage device.
Detailed information:
The principle of wind power generation is to use wind energy to rotate the blades of the windmill, and then use a multiplier of speed to increase the rotation speed to encourage the generator to produce electricity. According to current wind turbine technology, electricity production can start quickly.breeze of about three meters per second (the breeze level). Wind energy is becoming a craze around the world because it poses no fuel problems and does not produce radiation or air pollution.
Generally speaking, a wind turbine is a thermal energy engine that uses the sun as a heat source and the atmosphere as the working fluid. Wind energy uses natural energy. This is much better than diesel power generation. But if used in an emergency, it is still not as efficient as a diesel generator. Wind power is not considered a backup energy source, but it can be used long term.

Is wind power affected by wind?
Two points:
< p >Wind turbines do not produce electricity all the time. When there is no wind, it must still be in veille;The height of modern megawatt wind turbines is typically 65 to 90 meters and they are located in open wilderness. If you are upstairs and there is no wind, there could be two reasons: First, your building is not high enough. The most common 80 meter high wind turbine is equivalent to a 25 to 30 story building. The second floor is built in town. There are too many buildings in the city, making the wind unstable and turbulent everywhere. For example, a city is like a river bottom with many large rocks and the water flow is unstable and irregular. So when you are standing upstairs, sometimes there may be no wind and sometimes there may be gusty winds. The wind turbine is in the wind field, there is no obstruction, the wind speed is stable and lasts for a long time (wind measurement and corresponding simulation calculation are required). Additionally, the specific wind positionsilators are calculated to guarantee low turbulence and stable wind speed.
So the wind upstairs is different from the wind field, and the height of the building is different from the height of the fan. It's not because you don't feel the wind when you are upstairs that you cannot produce wind power.
Wind power is a clean energy technology that uses wind energy to produce electricity. Its power generation efficiency is affected by many factors, including the following:
< p. >Wind speed: Wind speed is one of the most important factors affecting the efficiency of wind power generation. The higher the wind speed, the faster the wind turbine spins and can produce more electricity. Normally, wind turbines start producing electricity when the wind speed is greater than 3 meters per second, and the efficiencyof wind energy production is highest when the wind speed is greater than 10 meters per second.Wind direction: Wind direction also affects the efficiency of wind power generation. Different wind directions will cause the blades of the wind turbine to be affected by different wind forces and directions, thereby affecting the efficiency of power generation.
Altitude: Altitude also affects the efficiency of wind power generation. In higher altitude areas, the air density is lower and the wind force on the wind turbine blades is also lower, which in turn affects the efficiency of electricity generation.
Temperature: Temperature also affects the efficiency of wind power generation. When the temperature is higher, the air density is lower and the wind force on the wind turbine blades is also lower, which in turn affects the efficiency of electricity production.
Wind Turbine Design and Quality: The design and quality of a wind turbine also affect its power generation efficiency. Excellent design can enable wind turbines to efficiently generate electricity at low wind speeds, and high-quality materials can extend the life of wind turbines.
