Abstract

The invention discloses an offshore wind energy resource assessment method based on multi-source remote sensing satellite wind speed correction. The method includes a first step of collecting and sorting long-time sequence multi-source satellite remote sensing wind field data sets (QuikSCAT, WindSAT and ASCAT); a second step of collecting and sorting a global oceanographic buoy data set that matches the space-time of satellite data; a third step of correcting the satellite wind speed by using a linear relationship between the buoy wind speed and the satellite wind speed; a fourth step of determining, according to the international and national standards for wind power generation, remote sensing assessment indicators for offshore wind energy resources; and a fifth step of calculating and comparing wind energy resource assessment results for different satellite combinations and the corresponding buoys. The method in the invention is conducive to the establishment of offshore wind energyresource survey methods based on satellite remote sensing data and provides low-cost and reliable data sources and assessment methods for offshore wind energy resource surveys.

Description

technical field [0001] The invention relates to the technical fields of remote sensing, energy and meteorology, in particular to a method for assessing offshore wind energy resources based on multi-source remote sensing satellite wind speed correction. Background technique [0002] The energy issue is a major issue restricting the current and future economic and social development of our country. Since the reform and opening up, the economy and society in my country's coastal areas have developed rapidly, and the demand for energy has grown rapidly. Facing the fact that traditional energy sources in this area are relatively scarce, and the potential for the development and utilization of offshore wind energy resources is huge, it is particularly important to develop offshore wind energy resources. urgent. With the advancement of science and technology, the acquisition of satellite remote sensing data and the advancement of satellite remote sensing wind field inversion method...
