漂浮式波浪能发电平台船艏楔形角及浮子质量的优化研究

Bow angle and buoys mass optimization on floating wave energy platform

基于漂浮式波浪能发电平台,通过对船艏楔形角及浮子质量的优化,以提高漂浮式波浪能发电装置的波浪能采集效率。对发电船及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,采用水动力分析软件AQWA对该模型进行了水动力时域仿真模拟,分析讨论了不同船艏楔形角和不同浮子质量对波浪能采集效率的影响。结果发现:沿波浪的传递方向,各浮子的采能效率依次减少,并且减小的幅度逐渐增加;综合考虑该平台状况和波况,浮子质量越小,船艏楔形角越大,波浪能的采集效率较高。

Based on the floating wave energy converter, the bow angle and buoys mass are optimized in order to improve wave energy acquisition efficiency of the floating wave energy converter. In this paper, the simulation model of the floating wave energy platform and buoys array are established, the related parameter is set, and the finite meshes are generated. Based on the above, the hydrodynamic time domain simulation of the established model is conducted by the hydrodynamic analysis software AQWA, which means to analyze the influence of the differences of the bow angles and the buoys mass lighter buoy mass is, the greater bow angle becomes, which causes the higher collection efficiency of the wave energy by considering of the platform and wave conditions.
