通过建立多浮体光伏阵列内部不同连接方式的数值模型,研究在规则波浪入射条件下连接器构型对海上多浮体光伏阵列纵摇响应、连接器弯曲角度、连接器受力、太阳辐照度接收效率的影响,评估海上多浮体光伏阵列的耐波性对连接器的依赖程度。从结果上来看,采用CSD连接器连接的多浮体阵列,运动响应优于铰链连接,承载能力强于螺栓连接,综合耐波性能优于以上两种连接器,且有较强的太阳辐照度接收能力。因此,CSD连接器适用于近海多浮体漂浮式光伏阵列,对加快海上漂浮式光伏商业进程有显著意义。
Abstract
The floating photovoltaic system has a large potential for development as a new type of power generation technology. Offshore floating photovoltaics face challenges with wave-induced damage to connectors in the array. Numerical models are created to analyze various connection configurations within multi-floating photovoltaic arrays. This study examines the effects of different connector configurations on the pitch response, connector bending angles, connector stresses, and receiving solar irradiance of multi-floating photovoltaic arrays in offshore conditions with regular wave incidence. The study evaluates the dependence of the seakeeping performance of offshore multi-floating photovoltaic arrays on connectors. The results indicate that the multi-floating array connected by the connector with spring damping （CSD） has a better motion response than the hinge connection, and it has a stronger load-bearing capacity than the bolt connection. The CSD connector is ideal for offshore multi-floating photovoltaic arrays due to its superior seakeeping performance and strong ability to receive solar irradiance compared to other connectors. The study is of great importance in expediting the commercialization process of offshore floating photovoltaics.
