초록

Recently, many renewable energy generating businesses are ongoing progress due to the introduction of the RPS(Renewable Portfolio Standards) as well as the needs of environmentally friendly energy resources. Researches on photovoltaic system are actively being processed since the photovoltaic system is relatively easy to install and becomes commercialized in many domestic application areas. Furthermore, the floating photovoltaic system is likely to be installed more actively since the conventional photovoltaic system requires relatively large areas of land. Also, the floating photovoltaic system is more efficient than photovoltaic system installed in land due to the operation in lower temperature. However, safety problems such as electric shock could arise since the cable should be installed in the water. In this paper, the leakage current and the voltage rising are measured and analyzed for the case when the cables are damaged connecting the floating photovoltaic system to the grid.
