| Abstract |
Floating Photovoltaic(PV) is one of the promising renewable alternative to replace fossil fuel energy. One of the issues about Floating PV(FPV) is how to ground its conductive materials effectively. Currently, the ground regulation of FPV denotes that grounding wire should not be floated in the water and laid in the ground. However, it is said that specific resistance of water is not higher than that of soil and water could be analyzed as soil. Two methods of water ground is suggested as water rectangular ground wire and conductive concrete anchor grounding. Test site of 100㎾ FPV is utilized to measure grounding resistance for each methods and GroundMat of PTW(Power Tools Window) is adopted to compare actual and theoretical values. |
