摘要

海上漂浮式光伏结构的稳定性是制约海上光伏发展为关键问题之一。目前针对多浮体光伏阵列的稳定性方面的研究较为欠缺,特别是在风浪联合作用下,连接件刚度对系统动态响应的影响机制尚未得到充分探讨。依据势流理论运用AWQA数值模拟技术对风浪联合作用下连接件刚度对多浮体光伏阵列动态响应的影响机制进行了探讨,选取某浮箱-支架式光伏电站单/双浮体作为研究的对象,构建系泊及铰接链接状态下铰接多浮体的运动方程,并对多浮体在六自由度上的运动进行了详尽的数值计算与分析。研究在不同风浪射入角度下连接件刚度对双浮体光伏系统运动响应及系泊力的关键影响。研究结果表明：随着浮体连接刚度的增加,运动响应则减小;合理设置连接件刚度能够显著提升浮体光伏平台的稳定性,减小运动幅值,并提出优化的刚度参考值。

Abstract

The stability of floating photovoltaic structures is one of the critical issues constraining the development of offshore floating photovoltaic. Currently, there is a lack of research on the stability of multi-floating photovoltaic arrays, particularly regarding the influence mechanism of connector stiffness on system dynamic response under combined wind and wave action. This study explores the impact mechanism of connector stiffness on the dynamic response of multi-floating photovoltaic arrays under combined wind and wave action based on potential flow theory, utilizing AWQA numerical simulation technology. A single/double-floating-body photovoltaic power station of the pontoon-support type was selected as the research object. The equations of motion for the hinged multi-floating photovoltaic in moored and articulated linkage states were constructed. Comprehensive numerical calculations and analyses were performed on the six degrees of freedom motion of the multi-floating bodies.The effect of connector stiffness on the motion response and mooring force of the double-floating-body photovoltaic system under different wind-wave incidence angles was studied. The results indicate that as the stiffness of the floating body connection increases, the motion response decreases. Setting the connector stiffness appropriately can significantly enhance the stability of the floating photovoltaic platform, reducing motion amplitude, and the optimization reference values for stiffness are proposed.
