结合点吸收式和筏式波浪能收集技术,提出一种阵列筏式波浪能发电系统。该系统可利用多组振荡浮子与漂浮平台之间的相对运动,同时收集多点波浪能,并转化为电能输出。详细叙述系统的结构和工作原理,进行系统受力和能量转化效率分析,理论计算表明单个浮子的最佳能量转化效率可达31.7%。进行实海况海试试验,通过数据分析发现,投入运行的振荡浮子数目越多,系统发电量越大,但能量转化效率越低。试验结果证明本系统原理正确,为海洋波浪能开发利用提供了一种新的方法。
The array-raft wave energy power generation system which combines floater wave energy convert technique with raft wave energy convert technique is put forward. The system can collect multipoint wave energy and output electricity energy by taking advantage of the relative shift between multi buoys and floating platform. The structure and working principle of the system is described. The theoretical calculation shows that the best efficiency of single floater is 31.7% after the force and energy convert efficiency were analyzed. A real ocean experiment is conducted and the test data show that the system will get more electricity energy if the buoys are more, on the other hand, the energy efficiency will drop. The ocean experiment proves that the array-raft wave energy power generation system’s principle is correct, which provides a new method to develop ocean wave energy.
