本文试图量化阵列布置对海上风电场性能的影响。阵列布局的特点是风力涡轮机之间的间距(沿着和横跨主流风向)以及它们的排列方式(对齐或交错)。利用大涡模拟程序来产生湍流边界层，并与执行机构线模型耦合来模拟旋转的风力机叶片的影响。控制情况(模拟Lillgrund农场)和敏感性运行是通过增加间距的各种组合来执行的，具有和不具有交错。研究发现，每隔一行错开是将容量因数从0.3提高到0.34、阵列损耗从36%提高到27%的最简单方法。最高的容量系数(0.4)和最低的阵列损耗(14%)是在交错布局下获得的，横跨主流风向的间距是原始风向的两倍。智能布局选择可以将阵列性能提高13%-33%。
This paper attempts to quantify the effects of array layout on the performance of offshore wind farms. Array layout is characterized by the spacing between wind turbines (along and across the prevailing wind direction) and by their alignment (aligned or staggered). A large‐eddy simulation code is utilized to create a turbulent boundary layer and is coupled with an actuator line model to simulate the effects of the rotating wind turbine blades. A control case (simulating the Lillgrund farm) and sensitivity runs are performed with various combinations of increased spacing, with and without staggering. Staggering every second row was found to be the simplest method to improve the capacity factor from 0.3 to 0.34 and array losses from 36% to 27%. The highest capacity factor (0.4) and the lowest array losses (14%) were obtained with a staggered layout with spacing across the prevailing wind direction that was twice the original. Smart layout choices can improve the array performance by 13%–33%.
