风切变分布差异研究及机组轮毂高度方案比选
摘要:以黑龙江地区某200 MW风电项目为例，研究不同区域风切变分布差异。通过激光雷达验证了测风数据准确性，并现场踏勘该项目地形地貌，分别分析并对比了数据时长不满1年、满1年后等情况下的风切变拟合规律。根据风切变分布差异，提出3种同机型不同轮毂高度排布方案，并对其进行经济性比选，结果显示，结合风切变排布的高低塔架混排方案度电成本最低。风切变分布差异研究为探寻经济性最优的机型轮毂高度方案提供了理论依据，研究结果可为大型风电项目的分析论证、机型方案选择等提供一定的参考。
Abstract：Taking a 200 MW wind power project in Heilongjiang as an example, the differences in wind shear distribution in different regions are studied. The accuracy of wind measurement data is verified through laser radar, and the terrain and landforms of the project are surveyed on-site. The fitting rules of wind shear are analyzed and compared under the conditions of data duration less than one year and after one year. Based on the differences in wind shear distribution, three schemes with different hub heights for the same type are proposed for economic comparison. The results show that the mixed arrangement of high and low towers combined with wind shear has the lowest levelized cost of energy. The study on the difference in wind shear distribution provides a theoretical basis for exploring the economically optimal hub height scheme, and the research results can provide a certain reference for the analysis and demonstration of large-scale wind power projects, as well as the selection of wind turbine schemes.
