I think: This is the science of wind turbine design.
1. Very small damping and very little power can make it run.
2. The shape of the propeller blade is scientifically designed on the windward side.
3. Due to the large area of the propeller and the super height of the wind turbine, even if you don't feel the wind at low ground level, it does not mean that there is no air flow at high altitude.
To sum up, wind turbines can operate even when you feel there is no wind.
Why do some wind power generators on the grassland rotate while others do not
Wind power generation is a clean energy technology that uses wind energy to generate electricity. Its power generation efficiency is affected by many factors. The influence of various factors includes the following aspects:
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 generating electricity when the wind speed is above 3 meters per second, and the efficiency of wind power generation is highest when the wind speed is above 10 meters per second.
Wind direction: Wind direction also affects the efficiency of wind power generation. Different wind directions will cause the wind turbine blades 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 areas with higher altitudes, the air density is lower, and the wind force on the wind turbine blades is also smaller, which in turn affects the efficiency of power 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 smaller, which in turn affects the efficiency of power generation.
Wind turbine design and quality: The design and quality of a wind turbine also affects its power generation efficiency. Excellent design can enable wind turbines to generate electricity efficiently at low wind speeds, and high-quality materials can extend the service life of wind turbines.
The parameters required for wind power calculation can be provided by the Xihe Energy big data platform (xihe-energy).
There are many reasons for this. If the wind speed is relatively small, near the cut-in wind speed of the wind turbine, due to terrain reasons, the wind speed will be different in local areas, and this situation will occur. In addition, if the unit fails and someone repairs it, it will stop. Also, the power grid company imposes power generation load restrictions on the power plant. For example, the wind is relatively strong now and it can generate 50,000 degrees per hour, but they only allow you to generate electricity per hour. With 20,000 kilowatt-hours of electricity, the unit will be shut down and the wind turbine will not rotate.
