摘要:

运行在上游机组后方的下游风力机由于风速降低和湍流增强而面临显著的性能挑战。这导致风能产量下降,并增加下游风力机的动态载荷。因此,实时监测与控制对于提升风电场性能已变得至关重要。一种有前景的解决方案是利用漂浮式海上风力机(FOWTs)所提供的额外灵活性,对风电场布局进行实时优化。本研究探索了一种动态布局优化策略,以在满足功率需求的同时最小化风电场中的尾流效应。考虑了两种场景:功率最大化和功率设定点跟踪。该方法涉及一个集中式风电场控制器对布局进行优化,随后由风力机控制器实现规定目标。每台FOWT采用模型预测控制来调节气动推力。该控制策略集成了一个动态风电场模型,该模型考虑了漂浮平台运动以及变化风况下的尾流输运。在一个由5 MW FOWTs组成的1x3风电场布局案例研究中,结果显示在第一种场景下,一小时内稳定能量产量相比静态布局提高了25%。在第二种场景下,期望功率输出被迅速且一致地实现。

英文摘要:

Downstream wind turbines operating behind upstream turbines face significant performance challenges due to reduced wind speeds and increased turbulence. This leads to decreased wind energy production and higher dynamic loads on downwind turbines. Consequently, real-time monitoring and control have become crucial for improving wind farm performance. One promising solution involves optimizing wind farm layouts in real-time, taking advantage of the added flexibility offered by floating offshore wind turbines (FOWTs). This study explores a dynamic layout optimization strategy to minimize wake effects in wind farms while meeting power requirements. Two scenarios are considered: power maximization and power set-point tracking. The methodology involves a centralized wind farm controller optimizing the layout, followed by wind turbine controllers to meet the prescribed targets. Each FOWT employs model predictive control to adjust aerodynamic thrust force. The control strategy integrates a dynamic wind farm model that considers floating platform motion and wake transport in changing wind conditions. In a case study with a 1x3 wind farm layout of 5 MW FOWTs, the results show a 25% increase in stable energy production compared to a static layout in one hour for the first scenario. In the second scenario, desired power production was swiftly and consistently achieved.
