Seaborne anemometry device and measuring method

Abstract

The invention provides a seaborne anemometry device and a measuring method. The seaborne anemometry device comprises a basic platform, an anemometer tower, a movable fixed platform and a laser radar anemoscope, wherein the basic platform comprises a first platform and a second platform; and the anemometer tower is arranged on the first platform. The laser radar anemoscope is movably arranged on the second platform or the movable fixed platform. The seaborne anemometry device is provided with the basic platform and the movable fixed platform, the anemometer tower is arranged on the basic platform, and the laser radar anemoscope is arranged on the movable fixed platform, so that anemometry information of more vertical levels and more space observation sites can be obtained, and the aims of observation and evaluation of early-stage wind energy resources in a wind power station, measurement of wake effects of fans in different positions after the wind power station is built and operated, post evaluation of the wind power station, and guidance, operation and management are realized.

Description

technical field [0001] The invention relates to the field of offshore wind power, in particular to an offshore wind measurement device and a measurement method for offshore wind measurement. Background technique [0002] At present, the most commonly used method for wind energy resource observation in the survey and design stage of offshore wind farms is to build an offshore wind measuring tower with the same height as the preset hub in the wind farm, and install wind speed and direction sensors at different levels of the wind measuring tower to conduct year-round observations. However, this traditional wind measurement scheme has several disadvantages. The observation level of the wind measurement tower is generally limited to 100 meters, and the wind speed between 100 meters and 150 meters has a crucial impact on the safety and production capacity of wind turbines. ; The wind measuring tower is only a point in the wind farm, and according to relevant regulations, the repre...

However, this traditional wind measurement scheme has several disadvantages. The observation level of the wind measurement tower is generally limited to 100 meters, and the wind speed between 100 meters and 150 meters has a crucial impact on the safety and production capacity of wind turbines. ; The wind measuring tower is only a point in the wind farm, and according to relevant regulations, the representative radius does not exceed five kilometers; the spatial distribution of wind energy resources in offshore wind farms that are relatively close to the shore and are obviously affected by the discontinuity of land and sea is uneven, so large-scale offshore For offshore wind farms, a single wind tower has insufficient coverage and representation
