摘要
针对近海风电场风资源评估的众多影响因素,利用风资源评估软件WAsP,结合某近海风电场工程实际并根据实测风数据,采用单变量分析方法对海面粗糙度模型、尾流耗散系数模型、逆温层模型、热通量模型等进行理论意义、取值原则和敏感性研究,旨在提升软件预测精度,提高风资源评估的准确性。结果表明:合理的风能参数模型和修正后的参数值可减小建模误差,提高风资源评估的精度,可为工程实际提供参考。
In view of the various factors that affect wind resource assessment in offshore wind farm,using univariate analysis combined with an actual offshore wind farm and its measured data,the wind resource assessment software WAsP is used to carry on the research on theoretical significance,valuefetching principle and sensitivity of sea surface roughness model,wake-decay coefficient model,inversion model and heat flux model,which aims at improving the accuracy of software prediction and wind resource assessment. The results show that reasonable wind energy parameter models and modified parameters can reduce the modelling error,and improve the accuracy of wind resource assessment,which could provide reference for actural project.
