【摘要】：针对海洋漂浮式太阳能发电装置,为分析海浪运动对其光照性能的影响,对比陆地环境下相同面积光伏电池的光照性能,分析两者之间的差距.首先总结了倾斜表面太阳辐射能的计算方法,分析了在海洋环境下应用这一模型的差异性,再将海浪简化,分析浮体在海浪中的运动特性及角度摆动规律,同时运用AQWA仿真软件,对浮体运动进行仿真,以验证浮体摆动角度计算的准确性,最后将静态的太阳辐射能计算模型与动态的浮体角度摆动相结合,得出海浪影响下光伏电池表面所接收到的太阳辐射能.将其与相同条件下以最佳接收角度固定安装的光伏电池所接收的太阳辐射能相比较,得出在海浪影响下浮体及光伏电池所接收的辐射能能够达到陆地最佳接收情况下的87.5%.
[Abstract]:In order to analyze the influence of wave motion on the illumination performance of marine floating solar power plant, the illumination performance of photovoltaic cells with the same area in terrestrial environment was compared and the gap between them was analyzed. This paper summarizes the calculation method of solar radiation energy on inclined surface, analyzes the difference of the model applied in ocean environment, and then simplifies the wave, and analyzes the motion characteristics and angle swing law of floating body in the ocean wave. At the same time, the AQWA simulation software is used to simulate the floating body motion in order to verify the accuracy of the calculation of the floating body's swing angle. Finally, the static solar radiation energy calculation model is combined with the dynamic floating body's angle swing. The solar radiation energy received by the photovoltaic cell surface under the influence of the waves is obtained. Comparing it with the solar radiation energy received by photovoltaic cells fixed at optimal reception angles under the same conditions, It is concluded that the radiation energy received by the floating body and photovoltaic cell under the influence of the waves can reach 87.5% of the best receiving energy on land.
