摘要

本文提出了一种评估风速数据修正对威布尔分布拟合影响的新方法。对声波探测与测距(SODAR)和MERRA-2基础数据进行了修正。SODAR数据通过湍流强度(TI)进行校正。MERRA-2数据校正使用国家气象研究所(INMET)气象站数据来寻找当地尺度因子。结果表明，修正后的数据与威布尔分布拟合较好，表明在风速平均值评价风资源时需要进行修正。风速数据也被应用于模拟商业涡轮机的能量生产，以展示总能量产生的对比。新方法表明，在风资源评价中必须考虑信息技术。

Assessment of wind resource considering local turbulence based on data acquisition with SODAR

This work presents a new methodology to evaluate the influence of wind speed data corrections in the fit of the Weibull distribution. Corrections are made for data measured by Sonic Detection and Ranging (SODAR) and MERRA-2 base data. SODAR data are corrected through Turbulence Intensity (TI). The MERRA-2 data correction uses National Institute of Meteorology (INMET) weather station data to find a local scale factor. The results showed that the corrected data present a better fit in the Weibull distribution and evidence that corrections are necessary when wind speed averages are used to evaluate the wind resource. Wind speed data were also applied to simulate the energy production by a commercial turbine to demonstrate the contrast in the total energy generated. The new methodology shows that IT must be considered in the evaluation of wind resources.

期刊介绍： Having been in continuous publication since 1977, Wind Engineering is the oldest and most authoritative English language journal devoted entirely to the technology of wind energy. Under the direction of a distinguished editor and editorial board, Wind Engineering appears bimonthly with fully refereed contributions from active figures in the field, book notices, and summaries of the more interesting papers from other sources. Papers are published in Wind Engineering on: the aerodynamics of rotors and blades; machine subsystems and components; design; test programmes; power generation and transmission; measuring and recording techniques; installations and applications; and economic, environmental and legal aspects.
