Unlike land-based photovoltaic power generation systems, floating photovoltaic power generation systems are installed in a reservoir or marine environment and use a floating body and mooring device. Therefore, it is difficult to evaluate structural safety. To evaluate the structural safety of a floating solar power plant, it is necessary to calculate the wind load and wave load in consideration of the floating body, mooring device, and joint. In this study, analysis was performed on the entire model of a 2 MW class floating photovoltaic power plant. To calculate the applied load, a two-dimensional (2D) flow analysis was performed to calculate the wind load acting on the solar panel. Then, wave analysis, including currents, was performed to calculate the wave load acting on the floating body. Through the analysis, the tension and displacement acting on the mooring device generated by the current, wind load, and wave load were confirmed. Finally, structural analysis was performed on the unit where the wind load, current, wave load, and mooring force acted the most. Thus, the structural safety of the floating photovoltaic power generation facility was evaluated.
