Color markings on wind turbine blades

Many fan blades do not have red dots, they are just eye-catching signs. The red paint on the blade tips is for aviation warning and is used during the day. The blades are curved, called pre-bent, and they are bent toward the wind receiving surface. In this way, when the fan is blown by the wind and does work, the blades are straight and can produce maximum power.

The panic button is red and its background is **. Activate the emergency stop by pressing the red button. During start-up, the operator must be careful if starting a wind turbine with ice on the blades.

The wind direction changes. When the wind turbine blades turn, what is the current generated?

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.

Do the blades of wind power generation rotate in one direction? Are the blades always turning to the right or to the left?

Wind turbines have pitch and yaw systems. The pitch system can adjust the windward angle of the blades when the wind speed changes, so that the impeller speed can be optimized and the maximum generator power can be achieved; The yaw system can adjust the windward angle of the impeller and the nacelle when the wind direction changes, so that the impeller always works in the wind direction.

1. The cabin will change with the change of wind direction.

2. The nacelle and the impeller are mechanically connected together. When the wind direction changes, the impeller and the nacelle will remain perpendicular to the wind direction.

3. Changes in wind direction will not affect the output of the generator. Only when the wind speed changes will the output power of the generator be affected.

To put it simply, the blades of a wind turbine are like the blades of a oscillating electric fan. Even if you shake your head left and right (or even shake your head in all directions like a ceiling oscillating fan on a train), the blades will not turn. Change, but the electric fan rotates when the wind blows the blades, and the generator generates electricity, and the blades rotate with the direction of the wind.If it rotates in the same direction against the wind to generate electricity, how can it generate electricity if it suddenly rotates clockwise and sometimes counterclockwise?
