The invention discloses a design method of an offshore floating type photovoltaic system and the floating type photovoltaic system, and relates to the technical field of photovoltaic power generation. According to the method, the assembly number range of the photovoltaic assemblies in each photovoltaic string is determined according to the target temperature of a set sea area, the first electrical data of the photovoltaic assemblies and the second electrical data of the inverter. The method comprises the following steps of: selecting a component number range, determining an array side length range of each photovoltaic array according to a sea wave wavelength in a set sea area, and then screening out a target component number corresponding to each path of photovoltaic string and a photovoltaic string number corresponding to each photovoltaic array by combining the component number range, the array side length range and the component size of the photovoltaic components. According to the number of the target assemblies and the number of the photovoltaic strings, the size and the number of floating bodies bearing each photovoltaic array are determined, all the floating bodies are fastened through mooring ropes, and at least one photovoltaic assembly is completely installed on each floating body. The system performance is optimized through multiple dimensions, so that the service life and the operation stability of the photovoltaic system in a set sea area can be ensured.

    本发明公开了一种海上漂浮式光伏系统的设计方法及漂浮式光伏系统,涉及光伏发电技术领域。所述方法根据设定海域的目标温度、光伏组件的第一电气数据以及逆变器的第二电气数据,确定每路光伏串中光伏组件的组件数量范围。并根据设定海域中的海浪波长,确定每个光伏阵列的阵列边长范围,然后结合组件数量范围、阵列边长范围以及光伏组件的组件尺寸,筛选出每路光伏串对应的目标组件数量和每个光伏阵列对应的光伏串数量。根据目标组件数量和光伏串数量,确定承载每个光伏阵列的浮体尺寸和浮体数量,各浮体之间通过缆绳形成紧固且分别完整安装至少一块光伏组件。通过多个维度优化系统性能,能够保证光伏系统在设定海域中的使用寿命和运行稳定性。
