摘　　要：风能参数的真实性直接关系到风电的经济性和开发价值,是近海风能资源利用面临的一大难题。基于双参数Weibull分布,利用浙江省沿海区域6个地面气象站点的实测数据,模拟计算卫星过境时次的风能参数,并将这些结果与按照《地面气象观测规范》的常规24次观测的日平均风速计算结果进行对比分析。结果表明,不同时次的模拟计算结果精度基本上达到了要求;通过数据融合增加观测时次,其计算结果精度将大大提高,卫星过境前数据的计算结果精度高于过境后的、下午过境卫星的数据计算结果的精度要高于上午的。这对选择不同时次的卫星数据评估近海风能资源具有指导意义。Wind power parameters of wind power is directly related to the authenticity of the economy and development value, is a big problem of the offshore wind power resource utilization.Based on the double parameter weibull distribution, the use of 6 ground meteorological site in Zhejiang coastal area at different times of the measured data, to simulate the satellite data wind energy parameters are calculated respectively, and the comparison of these results with the results calculated according to the national standard were analyzed.The results show that the calculation precision of different time periods are higher. Through the data fusion to increase the observation frequency, the accuracy of the calculation results will be greatly improved. The accuracy of the calculation result of the satellite transit data is higher than the transit,and the afternoon＇s accuracy is higher than in the morning.For this study based on satellite data to evaluate offshore wind resources for a long time study has important significance.
