摘要:
减轻风能成本的一种常用方法是通过个体桨叶控制(IPC)来减轻涡轮机叶片的周期性负载。本文采用了一种名为子空间预测重复控制(SPRC)的数据驱动IPC方法。该方法在缩放的双叶片风力涡轮机上进行验证。使用带有创新主动网格的开放喷嘴风洞生成可重复的湍流风条件。即使在这些高湍流条件下,也能实现显著的负载减少,同时限制执行器的 duty。此外,还将证明SPRC能够适应变化的运行条件。
英文摘要:
A commonly applied method to reduce the cost of wind energy, is alleviating the periodic loads on turbine blades using Individual Pitch Control (IPC). In this paper, a data-driven IPC methodology called Subspace Predictive Repetitive Control (SPRC) is employed. The effectiveness of SPRC will be demonstrated on a scaled 2-bladed wind turbine. An open-jet wind tunnel with an innovative active grid is employed to generate reproducible turbulent wind conditions. A significant load reduction with limited actuator duty is achieved even under these high turbulent conditions. Furthermore, it will be demonstrated that SPRC is able to adapt to changing operating conditions.
