摘要
为了加快发展非化石能源建设,坚持集中式和分布式并举,发展分布式海上漂浮光伏成为重中之重。基于DualSPHysics开源程序建立了中尺度无反射数值波浪水槽,并结合系泊浮箱运动状态和系泊线张力实验结果,验证了波浪水槽模型的可靠性。以分布式海上漂浮光伏为研究对象建立原尺寸模型,波浪传播方向上10个光伏板为1排,分析了单排光伏系统与多排光伏系统在5 m水深和多种波浪要素的波浪作用下光伏系统结构的整体受力和运动响应,以及4根系泊线的张力变化规律。结果表明,单排光伏系统4根系泊线的张力周期性同步变化,与波高存在非常好的线性关系,在保证单一浮体极限受力条件下推出的极限波高为1.63 m。对多排光伏系统运动规律和系泊线张力进行综合分析,得出多排光伏系统阵列的长宽比应小于3.0。
In order to accelerate the development of non-fossil energy construction,adhere to centralized and distributed simultaneously,the development of distributed offshore floating photovoltaic has become a top priority.In the present work,a mesoscale non-reflective numerical wave tank was established based on the DualSPHysics open source codes,and the reliability of wave tank model was verified by combining the experimental results of the mooring pontoon motion state and the mooring line tension.Taking the distributed offshore floating photovoltaic system as the research object,the original size model was established,and ten photovoltaic panels in the wave propagation direction were arranged in a row.The overall force and motion response of the photovoltaic system structure and the tension variation of four mooring lines under wave action of 5 m water depth and various wave elements were analyzed.The results show the tension of four mooring lines of single-row photovoltaic system changes periodically and synchronously,and that a good linear relationship with the wave height is observed.The limit wave height is 1.63 m under the condition of ensuring the ultimate force of a single floating body.By analyzing the motion law of multi-row photovoltaic system and mooring line tension,it is concluded that the length-width ratio of multi-row photovoltaic array should be less than 3.0.
