A Study on Development of Rotary Structure for Tracking-Type Floating Photovoltaic System

摘要

K-water (Korea Water Resources Corporation) in Korea is installing and commercially operating 100 kW and 500 kW floating photovoltaic system on top of the water surface of Hapcheon Dam Reservoir. However, existing floating photovoltaic system is a fixed-type that requires the optimal angle of about 33 degrees with the azimuth due south, and track-type floating photovoltaic energy that yields greater generation with the same capacity is demanded. Accordingly in this study, FRP materials were selected for the structure of track-type floating photovoltaic system with a round rotary model to develop a track-type floating photovoltaic system. Finite element analysis and wind load analysis by wind tunnel experiment were performed to analyze safety of the structure. In addition, durability of the structure was analyzed with tensile test, compression test, and dynamic test The floating photovoltaic system structure for which stability and durability were verified through this experiment and analyses is utilized as the core technology of the world's first 100 kW track-type floating photovoltaic generation system for commercial power generation.
