该文将当前主流高干舷海上光伏设计归为4种典型的浮筒桁架组合形式,并展开综合性能对比分析。基于OrcaFlex平台建立时域水动力分析模型,并在Matlab中建立考虑运动影响的动态功率评估模型。然后,通过水池模型试验和光伏标准测试结果,验证所建模型的有效性。最后,分别对比静水、规则波以及非规则波下4类典型结构的综合性能。研究结果表明竖直浮筒与半浸没水平浮筒的组合形式综合表现更佳,在保证正气隙的同时具有较小的系泊力,且参数分析表明增加水平浮筒直径能显著改善气隙表现。
Abstract
This paper classifies current high-freeboard OFPV （Offshore Floating Photovoltaic） designs as four typical pontoon-truss structures, followed by a comprehensive performance analysis. Firstly, a time-domain hydrodynamic model was established in OrcaFlex, and a dynamic power prediction model incorporating motion effects was developed using MATLAB. These models were then validated against model experiments and standard test results. Subsequently, the comprehensive performance of the four structure types was compared under static water, regular wave, and irregular wave conditions. The results demonstrate that the structure combining vertical pontoons with semi-submerged horizontal pontoons delivers superior performance, achieving a positive air gap while maintaining lower mooring forces. Parametric analysis further indicates that increasing the diameter of the horizontal pontoons significantly improves air gap performance.
