摘要
以新疆某风电场每10 min的测风数据为基准进行风电场风资源评估;基于3种不同时间间隔(30min,1 h,2 h)的测风数据,并考虑尾流影响,利用Wind PRO软件对该风电场产能进行了评估;通过对比不同时间间隔测风数据的发电量误差,得出与该风电场风机发电特性最接近的测风时间间隔。文章阐述了风电场风资源评估的基本流程,利用先进的风资源评估软件,对进一步开发低风速风资源提供了有力的技术支持。该研究结果能够对精细化评估风电场产能及测风数据时间间隔的选取提供指导。
Based on the wind speed data(10 rain for each interval) of a wind farm in Xinjiang, the wind resource of the wind farm is assessed. Considering the influence of wake stream in three different intervals which are 30 min, 1 h, and 2 h respectively, capacity of the wind farm is estimated with the software named Wind PRO. By comparing generation error of different intervals, the optimal interval of wind speed measurement that can match the generation characteristics best is obtained. The basic technological process of wind farm wind resource assessment is expressed in this paper, combining with advanced wind resource assessment software, a strong technical support is provided for further development of low-speed wind resource. The study results can also provide some guidelines for refine estimation of wind farm capacity and selection of wind speed measurement interval.
