摘要
提出了一种新型多点阵列式波浪能发电装置，叙述了装置的工作原理。对该装置浮子阵列部分建立了数值模型，进行了相关参数设置及有限元网格划分。以数值模型为基础，分析讨论了不同波向时浮子阵列被布置成圆周式、双列式和单列式3种情况下的水动力响应特点以及浮子间距对各浮子波浪能吸收的影响。经研究发现，不同波向下，圆周式布放的浮子阵列的平均振幅最大，较少受到波浪传递方向的影响，同时，该方式下浮子间距为8～10m时是最佳浮子距离。
A new multipoint direct-drive wave energy converter is presented and the device＇s working principle is described. The simulation model of the buoys array was established and parameter setting and finite element mesh generation were conducted. This model was used to analyze the hydrodynamic response characteristics of the buoys array under different wave directions with the buoys being in three arrangements including： a circular type, a double rows type and a single row type. The influence of different buoy arrangement types on energy conversion capability has also been examined. Results reveal that the buoy array is more stable and efficient when all of the buoys are arranged in circular type and the best buoy spacing is about 8 to 10 meters.
