Abstract

This paper presents a study investigating the effects of surface roughness on airfoil performance and its consequences for wind turbine energy yield. This study examined 51 sets of experimental data across 16 airfoils to identify trends in roughened airfoil performance. The trends are used to formulate a novel ‘roughness evolution parameter’ that can be applied to airfoils with no roughened data available to predict the impact of roughness on performance. Blade element momentum theory is used to model the performance of the DTU 10 MW reference wind turbine, with uniformly roughened blades emulated using the roughness evolution parameter. An annual energy production loss between 0.6–9.6% is found for the DTU 10 MW turbine when considering a plausible range of values for the roughness evolution parameter derived from the experimental data. A framework has been developed to evaluate how the roughness evolution parameter changes over time, informed by observed changes in wind farm performance from previous studies.

参数化粗糙度演化对风力机性能的影响

本文提出了一项研究，调查了表面粗糙度对翼型性能的影响及其对风力发电机发电量的影响。这项研究检查了51组实验数据跨越16翼型，以确定在粗糙翼型性能的趋势。这些趋势被用来制定一种新的“粗糙度演化参数”，可以应用于没有粗糙数据的翼型，以预测粗糙度对性能的影响。采用叶片单元动量理论对DTU 10mw参考风力机进行了性能建模，采用叶片粗糙度演化参数对叶片进行了均匀粗化仿真。当考虑从实验数据得出的粗糙度演化参数的合理值范围时，发现DTU 10mw涡轮机的年发电量损失在0.6-9.6%之间。根据先前研究中观察到的风电场性能变化，已经开发了一个框架来评估粗糙度演化参数如何随时间变化。
