Wind power detection device for wind power station

Technical Field

The invention relates to the technical field of detection devices, in particular to a wind power detection device for a wind power station.

Background

Wind speed is taken as an important information parameter in the fields of production, weather, civil aviation, electric power, national defense, transportation and the like, and the detection technology of the wind speed is widely concerned and researched by people in recent years; the wind speed and the wind direction are very important parameters reflecting meteorological conditions, and have important influence on environmental monitoring, air conditioning and industrial and agricultural production, so that the method has important practical significance in quickly and accurately measuring the wind speed and the wind direction.
