摘要

评估低空气密度对风电叶片性能的影响,采用GH-Bladed计算平台比较不同叶片调整方法对风电机组发电量和载荷的影响。研究发现：低空气密度会严重破坏叶片气动性能,导致风电机组达到额定功率的风速更高,此外还会扩大叶片表面的失速范围,导致失速风险增加。在低空气密度条件下,安装涡流发生器是避免叶片发电损失、保证机组载荷稳定性的有效解决方案。在无载荷约束的情况下,增加叶片的弦长或优化扭角分布均是提高叶片气动性能的高效方法。

Abstract

This paper evaluates the impact of low air density on the performance of blades for a high-power wind turbine. The GH-Bladed computing platform was used to compare the blade performance and turbine load in steady wind condition. The study found that low air density severely weakens the aerodynamic performance of the blades, leading to a delay in achieving rated power for wind turbines. Low air density expands the stall range on the blade surface, leading to an increase in stall risk. Under low air density conditions, installing vortex generators is an effective solution to avoid the loss of blade power generation, and ensure the load stability of the wind turbine. Without load constraints, however, increasing the blade chord length or optimizing the twist angle distribution is a highly efficient technique for improving blade aerodynamic performance.
