Wind turbines include: "waiting state", "maintenance state", "fault state", "overload state", "natural causes" and "power limit".
Waiting for the wind: The wind is very small and cannot turn the wind turbine to generate electricity, but it is still facing the wind. The term is "yaw".
Inspection: Regular inspection, maintenance, oil filling, torque adjustment, etc. are carried out every year to maintain the fan, as well as maintenance.
Fault: There is a fault somewhere in the fan and it cannot operate.
Overload: The wind has exceeded the wind speed that the fan can withstand, and the blades become smooth and self-protecting.
Natural causes: such as lightning strikes, earthquakes, floods, etc.
Power limit: The national grid does not need so much electricity, so some of it will be stopped.
I think your problem seems to be that there is no wind, so it automatically looks for wind, or malfunctions. But when it stops a lot, the wind is very small. Although people can feel it, it is a huge thing after all. , so it has not reached the power generation point. When I was working on the wind turbine, the wind was very strong. The higher the height, the stronger the wind. I hope you can be satisfied with my answer, because I am a wind turbine worker myself. These are all I typed it myself, I hope it will be adopted.
If the poster's wind turbine does not turn in strong winds, the situation may be as follows:
1. Check whether the three-phase AC line of the generator is short-circuited
2. Whether the fan blades are installed backwards
3. Whether the motor is burned out
4. Bearing problems
The other two fans of the original poster Question:
When a person on the ground feels no wind but the fan blades rotate very fast, this is normal, because of course people on the ground feel there is no wind, and when the fan is several meters high, the direction of the wind will change. There is a difference. The main thing is to see if the leaves are moving. If the leaves are obviously windy, it is normal for the fan to rotate so slowly, but the other one does not rotate. How far is the distance between the two units? If it is too close This is normal, because the two units cannot be installed too close to each other, which will affect its overall effect. In addition, the landlord knows that there must be no high-rise buildings around when installing the fan, and it is best to install it in an open area.
As far as these situations are concerned, could you please check if there are any of the above situations?
