摘要

主动流量控制器(AFCs)已显示出良好的负荷缓解潜力。然而，AFCs在风力涡轮机叶片上的应用仍处于试验阶段。本文研究了AFCs的减载能力与它们在叶片跨上的位置的关系。特别是，一种分析方法是为了最大限度地减轻负荷，通过优化定位afc沿叶片跨度。将所提出的分析方法得到的结果与经过验证的基于BEMT的代码(WTAC)进行了比较和验证。研究发现，仅根据弦的几何形状就可以计算出afc的最佳位置。

A simple method to determine the optimal location of active flow controllers on wind turbine blades

Active flow controllers (AFCs) have shown promising load alleviation potential. The implementation of AFCs on wind turbine blades remains, however, experimental. The present paper investigates the load alleviation capability of AFCs as a function of their location along the blade span. In particular, an analytical method is derived in order to maximise load alleviation by optimally locating AFCs along the blade span. The results obtained by the proposed analytical method are compared and validated with a validated BEMT based-code (WTAC). It is found that the optimal location of AFCs can be calculated based exclusively on the chord geometry.
