面向海上太阳能资源开发，提出一种轻量化单层框架式漂浮式海上光伏支撑结构。为应对极浅水、大潮差给漂浮式海上光伏阵列系泊系统设计带来的极大挑战，考虑风、浪、流等环境载荷联合作用，采用时域耦合动力分析方法对漂浮式光伏阵列与系泊系统整体动力响应进行数值仿真，探究不同系泊参数对模块阵列运动响应和系泊缆受力等的影响规律。结果表明，合理选择系泊半径、浮子位置、浮子净浮力和预张力大小等可有效改善漂浮式海上光伏模块阵列的运动响应和系泊缆张力。基于此对系泊系统进行优化设计，并给出满足工程要求的系泊系统设计方案。

Optimal Design of Mooring System for Floating Offshore Photovoltaic Array in Ultra-shallow Water with Large Tidal Ranges

For the development of offshore solar energy resources, a lightweight single-layer frame floating photovoltaic supporting structure is proposed. In order to address the great challenges in the design of the floating offshore photovoltaic array mooring system brought by the environmental conditions of extremely shallow water with large tidal ranges, the time-domain coupled dynamic analysis is adopted to simulate the whole dynamic response of the floating photovoltaic array and mooring system and the influence of different mooring parameters on the motion response of the module array and the tension of the mooring lines are investigated considering the combined effects of the environmental loads such as wind, wave and current. The results indicate that the motion response and mooring line tension of the floating offshore photovoltaic module array can be effectively improved by reasonable selection of the mooring radius, buoy location, buoy net buoyancy and pre-tension. Based on this, the optimal design of the mooring system is carried out and the mooring system design meeting the engineering requirements is given.
