论文摘要
这项工作的目的是评估功率起飞（PTO）系统不同程度的适应性程度对密集波能转化器（WEC）阵列功率吸收的影响。适应性通过透射率包括在模拟中，该传输比缩放了浮力相对于浮子运动产生的力的力。使用了数值模型，其中考虑了浮点数与PTO中非线性之间的流体动力相互作用。该数值模型的较低计算成本使得可以在不规则波中研究密集的WEC阵列的功率提取，从而轻松创建功率矩阵和其他性能指标。该方法应用于海洋掠夺者WEC的案例研究，以展示通过包含传输比的潜在性能改善。分析表明，包括高度的适应性和选择WEC数组配置和PTO设计特定于设计过程中潜在部署位置的设计可能会导致提取功率的增加。
The aim of this work is to assess the influence of different degrees of adaptability of the power take-off (PTO) system on the power absorption of dense wave energy converter (WEC) arrays. The adaptability is included in simulations through a transmission ratio that scales the force actuating the PTO relative to the force generated by the motion of a floater. A numerical model is used in which hydrodynamic interactions between floaters and nonlinearities in the PTO are considered. The lower computational cost of this numerical model makes it possible to study the power extraction of a dense WEC array in irregular waves to easily create power matrices and other performance metrics. The methodology is applied to the case study of the Ocean Grazer WEC to showcase the potential performance improvements achieved through the inclusion of a transmission ratio. The analysis shows that including a high degree of adaptability and choosing WEC array configurations and PTO designs specific to potential deployment locations early in the design process can lead to an increase in extracted power.
