中、微尺度嵌套技术进行大范围风资源评估及验证

Large Area Wind Resource Assessment and Test Based on Middle And Micro-scale Nesting Technology

对于规划区域较大的沿海风场,以往的单一、线性微尺度模型模拟大范围海陆风的分布规律不确定性较大。本文针对河北黄骅北部区域风电场项目,采用中尺度大气数值模式结合微观模型WT软件超大范围的风流场计算模块,进行此项目的风资源评估,得到规划范围高精度的风资源图谱,并通过现场多个测风塔处风速模拟值的误差分析,验证中、微尺度嵌套技术在大范围沿海(特别是低风速)风场进行风资源计算评估的可靠性,实现快速的大范围风场高精度风资源评估和风电场的整体开发规划。

For large littoral wind field, there is higher uncertainty of large area sea-land breeze distributionrule of previous single and linear micro-scale model. The paper is aimed at studying wind power project ofHebei Huanghua Northen area, combined linear micro- scale atmospheric numerical model with microvisualmodel WT software to calculate mode by large range of wind field, assess wind resource, get the accuratewind resource map with range planning, analyze error of wind speed simulation value at various anemometertower, test wind resource assessment reliability of middle and micro-scale nesting technology in large areasea-land, rapid achievement, large scale accurate wind resource assessment and integral development planning of and wind power project.
