Problems solved by technology

However, lidar often needs to be placed on the work platform, which occupies a small work space, and because the radar is fixedly placed, affected by the shadow effect of the tower, it is impossible to measure the incoming wind in the direction of the tower behind

Abstract

The invention discloses an offshore scanning type laser radar wind measuring device and method. The device comprises a tower climbing operation platform, a sliding rail, a support, a radar cabin, a scanning type laser radar wind measuring instrument, a control system and a power system. The sliding rail is arranged on the tower climbing operation platform; the sliding rail is annular and concentric with a fan tower; the scanning type laser radar wind measuring instrument is arranged in the radar cabin; the face, away from the fan tower, of the radar cabin is open; the scanning type laser radarwind measuring instrument and the control system are arranged in the radar cabin; the power system is arranged on the radar cabin; and the output end of the power system is connected with the slidingrail. The annular sliding rail is erected on the basis of an existing tower climbing operation platform of the offshore wind turbine generator, and the cabin provided with the scanning type laser radar wind measuring instrument moves on the sliding rail through roller wheels at the tail end of the support, so that measurement of the wind speed and the wind direction of the space with different heights in the 360-degree range through the laser radar is achieved, and the measurement is not affected by the cabin fixing orientation and the tower shadow effect of a tower drum and is not affected by vibration and shaking of a fan cabin.

Description

technical field [0001] The invention belongs to the technical field of offshore wind power, and in particular relates to an offshore scanning laser radar wind measuring device and method. Background technique [0002] With the development of measurement technology, new wind speed and direction measurement methods are also emerging. In 2017, the IEC released a new version of the IEC61400-12-1 standard, which recognized the wind speed results measured by ground-based lidar, and gave specific regulations for the mutual verification of the measurement results of ground-based lidar and wind measuring towers. [0003] The offshore environment is harsh and complex. Without fixed ground conditions, wind turbines can only be used as a basis for placing lidar. According to the placement location, offshore wind turbine lidar can be divided into lidar arranged on the top of the nacelle and lidar arranged on the foundation of the wind turbine. The laser radar arranged on the top of the...
