基于ASCAT风场数据的中国近海风能资源评估
Wind resource assessment in the offshore of China based on ASCAT wind data
摘要
Abstract
Wind field data retrieved from the satellite can be a valuable supplement to on-site meas urement and of great significance for offshore wind resource assessment.The daily wind speed data retrieved from ASCAT was compared with the buoy data near the coast of the United States and China.Resuits show that the root mean square error of wind speed was 1.27 m·s-1 in compared with the wind speeds of NDBC buoys.Then,the ASCAT daily data and offshore buoy hourly data were used to calculate the mean wind speed,wind power density and the Weibull probability density function.The residual errors of mean wind speed and wind power density associated with ASCAT and individual buoy were respectively less than ±0.5 m·s-1 and ±50 W·m-2.These residual errors of ASCAT compared with buoy mean wind speed and wind power density were respectively less than ±8％ and ± 12％.The Weibull wind speed distribution of ASCAT data shows good agreement with the result of buoy data.Therefore,ASCAT wind data can provide useful wind parameter information for offshore wind resource assessment.The spatial distribution of wind resources in the coast of China at the height of 10 m and 70 m from 2007 to 2015 were analyzed by using ASCAT wind speeds.The result indicates that the most favorable wind conditions are along the coastal area in the Taiwan Strait.关键词
