Abstract

The invention provides a complex terrain three-dimensional scanning radar wind measurement system, method and equipment. The system comprises three-dimensional scanning radars used for collecting the radial wind speed at a to-be-measured point; and a first industrial personal computer used for sending a start-stop instruction to the three-dimensional scanning radar and calculating the second-level horizontal wind speed and the vertical wind speed of the to-be-measured point according to the radial wind speed collected by the three-dimensional scanning radars. The number of the three-dimensional scanning radars is three, and the three three-dimensional scanning radars are all in communication connection with the first industrial personal computer. According to the system, more accurate meteorological data can be obtained, and more reliable data support is provided for a wind power plant during wind resource measurement.

Description

technical field [0001] The invention belongs to the technical field of wind power generation, and in particular relates to a complex terrain three-dimensional scanning radar wind measurement system, method and equipment. Background technique [0002] Current lidar wind measurement is a relatively high-precision telemetry technique. The laser radar system emits a high-spectrum-purity laser beam into the detection airspace, and the aerosol particles in the atmosphere interact elastically with the laser beam. After the backscattered echo optical signal is effectively received by the radar signal transceiver system, it passes through the high-sensitivity optical frequency heterodyne The detection technology can accurately invert the measured Doppler spectrum information to obtain wind field information such as wind speed and wind direction. At present, the lidar on the market has been approved for wind measurement in flat terrain, but due to the limitation of its principle, the...
