为探究风况条件对萨沃纽斯风力机集群功率输出和安装方向的影响
基于变转速控制策略和计算流体力学仿真结果
获得了集群在我国8个典型站点不同安装方向下的输出功率
分析了集群在实际风况下的最佳布局规律
并验证了规律的普适性。仿真结果表明:在沈阳、厦门、昆明、呼和浩特、青岛、喀什、大连以及郑州8个站点合理安装集群
可使单台机组的输出功率分别提升至原来的1.14、1.23、1.31、1.20、1.21、1.24、1.12、1.11倍; 对于有明显单一主风能风向的地区
集群应正对此方向摆放; 对于两个主风能风向相位差较大的地区
需选择两者中周围风能更丰富的方向排布集群; 对于有3个主风能风向、主风能风向不明显或风能分布比较均匀的地区
应先使机组相互格挡的方位避开风能相对集中区
再选择风能资源较丰富的方向排布集群。该研究可使实际风况下萨沃纽斯风力机集群耦合增益最大化
并为复杂风场条件下集群安装方向的选择提供参考。
To explore the effect of wind conditions on the power output and installation direction of the Savonius wind turbine cluster
the power output of the proposed cluster under different installation directions at eight typical sites in China was obtained based on the variable speed control strategy and computational fluid dynamics simulation results. The optimal layout rules of the cluster under actual wind conditions were analyzed
and their universality was verified. The simulation results show that the output power can be increased to 1.14
1.23
1.31
1.20
1.21
1.24
1.12 and 1.11 times by properly installing cluster in Shenyang
Xiamen
Kunming
Hohhot
Qingdao
Kashgar
Dalian and Zhengzhou. For regions with an apparent single main wind energy direction
the cluster should be placed facing that direction. For regions with a significant phase difference between two main wind energy directions
the cluster should be arranged in the direction with more abundant wind energy resources. For regions with three main wind energy directions
no obvious main wind energy direction
or relatively uniform wind energy distribution
the cluster should be arranged in a direction avoiding the area where the wind turbines block each other
and then the direction with more abundant wind energy resources should be selected. This study maximizes the coupling gain of the Savonius wind turbine cluster under actual wind conditions and provides references for the selection of cluster installation directions under complex wind farm conditions.
