Because the wind power of the wind turbine does not have a fixed energy input like thermal power and hydropower, that is, the wind is sometimes strong and sometimes weak . The energy production principle of the wind turbine is that of wind. The speed reaches the generator's wind start speed before it can spin. When the wind is weak, power generation cannot be carried out automatically.
How does the wind turbine PLC program work. Does the wind turbine produce electricity?
Two points:
Wind turbines do not produce electricity all the time. When there is no wind, it should still be on standby;
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 wind turbinethe most common 80 meters high is equivalent to a building of 25 to 30 floors. 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, specific fan positions are calculated to ensure 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 wind turbine. If you can't feel the wind when you're upstairs, it's notis not the case. This does not mean that wind energy cannot be produced.
I think: This is the science of wind turbine design.
1. Very low damping and very little power can make it work.
2. The shape of the propeller blade is scientifically designed on the windward side.
3. Due to the large surface area of the propeller and the high height of the wind turbine, even if you do not feel the wind at ground level, it does not mean that there is no wind. high altitude airflow.
In summary, wind turbines can operate even when you feel there is no wind.
