Background
With the continuous development of offshore wind power industry in China, the site of an offshore wind power plant gradually moves from a coastal beach to a shallow sea, and at present, the plant is tightened to enter a sea area with deeper water depth. Due to long ocean operation period, high risk and high operation difficulty, the wind power plant construction faces the problems of long period, high investment and high risk. How to accurately and effectively evaluate offshore wind resources (particularly wind resources in deep sea areas) and select sea areas with rich wind resources is a difficult problem which puzzles the rapid development of the offshore wind power industry.
In recent years, the rising of offshore lidar wind measurement buoy technology provides a certain reference basis for offshore wind resource assessment. The sea laser radar wind measurement buoy technology adopts a mode of combining a laser radar and a sea buoy, the buoy carries the laser radar, and the laser radar obtains wind speed data. Because the buoy body and the carried laser radar fluctuate along with ocean current to generate yaw, pitch and roll, the wind measurement data of the laser radar carried on the buoy body has great inaccuracy (second-level data), and the wind speed characteristics cannot be directly represented. Therefore, after collecting the lidar anemometry data (second level), the traditional anemometry buoy body needs to perform complex data processing to obtain the wind speed data of a specific position.
At present, two data processing methods are adopted in the market: one method is to use a linear regression method to correct the lidar measurements at sea with the land measurements. The disadvantages of this approach are: the measured data cannot reflect the real condition of the wind speed; the second-level data error is large; in extreme weather conditions, the data is distorted. Another method is to correct wind speed data using a motion sensor, which has disadvantages in that: a cumbersome algorithm is required (at present, a motion compensation algorithm that is not yet standardized); the data processing capacity is large; additional sensor configurations are required; the second-level data cannot reflect the real condition of the wind speed.
