Background

The original traditional fan mostly depends on an anemometer arranged on the top of an engine room to measure a wind field in real time, and the collected horizontal wind speed and wind direction are transmitted to a main control system. This approach cannot accommodate wind field changes, especially sudden changes and the like.

In the wind energy industry, laser-based wind sensors have become a complement to wind sensing devices. Laser wind-finding radar is unique in its ability to accurately measure wind speed and direction at a distance. The wind direction and speed can be accurately determined at the top of the nacelle before the wind has reached the blades. With the data, the state of the fan can be adjusted in advance according to the wind condition. Therefore, the increase of the generated energy is inevitably brought, and meanwhile, the abrasion of fan parts is reduced.
