摘　　要：漂浮式光伏作业海域水深浅、潮差大的特征显著,极浅水条件下潮位的变化将对漂浮式光伏系泊系统的定位能力产生显著的影响,传统系泊方案无法满足漂浮式光伏极浅水、大潮差长期稳定系泊定位的需求。在传统浅水悬链线系泊系统的基础上,通过在系缆不同位置处布置系列重物块来改变不同水深条件下系缆的空间构型和水平回复力特性,提出了一种改进混合式系泊系统以满足漂浮式光伏结构不同潮位下的系泊定位需求。以1 MW漂浮式光伏方阵为例,对混合式系泊系统在不同水位和荷载方向下的适用性进行了数值研究。结果表明,不同水位下漂浮式光伏模块运动响应幅值差异不超过14%,高水位下系缆张力响应明显大于低水位下系缆张力响应,其张力响应幅值差异不超过268%,表明文中提出的混合式系泊系统对极浅水、大潮差漂浮式光伏结构具有较好的系泊定位性能。The characteristics of floating photovoltaic operating waters are notably influenced by shallow water depths and significant tidal ranges.The variations in tidal levels under extremely shallow water conditions can significantly affect the positioning capabilities of floating photovoltaic mooring systems.Traditional mooring schemes fail to meet the long-term and stable positioning requirements for floating photovoltaic structures in extremely shallow water and large tidal range scenarios.Building upon traditional shallow water catenary mooring systems,this study proposes an improved hybrid mooring system designed to adapt the spatial configuration and horizontal restoring force characteristics of the mooring cables by arranging a series of weights at various points along the cables.This enhancement aims to satisfy the mooring positioning requirements of floating photovoltaic structures under varying tidal levels.Using a 1 MW floating photovoltaic array as a case study,numerical investigations were conducted to assess the applicability of the hybrid mooring system under different water levels and loading directions.The results indicate that the amplitude differences in motion responses of floating photovoltaic modules across varying water levels do not exceed 14%.The cable tension response at high water levels is significantly greater than that at low water levels,with amplitude differences in tension responses not exceeding 268%.These findings suggest that the proposed hybrid mooring system exhibits good mooring positioning performance for floating photovoltaic structures in extremely shallow water and large tidal ranges.
