湍流风场下三风机气动功率优化

Optimization of Aerodynamic Power of Three Wind Turbines in Turbulent Wind Farm

  • 摘要:
    目的 在全球能源结构转型和气候变化应对的大背景下,风能作为清洁、可再生的能源之一,其利用效率的优化已成为当前能源领域研究的重点。为减小因风机间尾流效应对风电场输出功率的影响,提高风电场效率,对风机进行合理布局是很有必要的。
    方法 运用Fast Farm模拟技术,分别研究了串列以及错列布置下随着风机间间距的改变对于湍流风场中3台NREL 5 MW风机输出功率及功率提升率的变化情况。
    结果 当风机间间距增大时,可以明显提升后排风机的输出功率,但其提升程度有所不同,其中,当风机纵向间距由5D增加到6D及10D增加到11D时,可使风电场发电量得到较大提升;对于风机间横向间距在合理取值范围内,可使得风电场布局达到最优。
    结论 文章对风机间间距进行了较为详细的划分,通过不同工况下对风电场功率影响程度分析可知在串列及错列条件下对于风机的优化布局存在差异,为风电场的布局优化提供了一定的参考。

     

    Abstract:
    Objective In the context of global energy structure transformation and climate change response, wind energy, as one of the clean and renewable energy sources, the optimization of its utilization efficiency has become the focus of current research in the energy field. In order to reduce the influence of the wake effect between wind turbines on the output power of wind farms and improve the efficiency of wind farms, it is necessary to carry out a reasonable layout of wind turbines.
    Method Using Fast Farm simulation technology, the effects of changing the wind turbine spacing on the power and its improvement rate of three NREL 5 MW turbines in a turbulent wind farm under tandem and staggered arrangements were studied.
    Result When the spacing between turbines increases, the output power of the rear turbines can be significantly improved, but the degree of improvement is different, in which when the longitudinal spacing of the turbines is increased from 5D to 6D and from 10D to 11D, the power generation of the wind farm can be greatly improved. A reasonable range of values for the lateral spacing between wind turbines is derived, which allows for an optimal layout of the wind farm.
    Conclusion In this paper, the spacing between wind turbines is divided in more detail, and through the analysis of the degree of impact on the power of wind farms under different conditions, it can be seen that there are differences in the optimization of the layout of the wind turbine under the conditions of series and staggered rows, which provides a certain reference for the optimization of the layout of wind farms.
