Experimental Study and Analysis of the Generated Electric Power of Salter Duck-Ocean Wave Energy Harvester (OWEH) due to Additional Weight Change and Wave Amplitude

Abstract:

Among ocean energy, wave energy is one of the energy which has not been utilized optimally. As Indonesia has the longest coastline in the world, the development of OWEH is very important. In this paper, an experimental study and analysis of the generated electric power of Salter Duck type OWEH due to additional weight change and wave amplitude was carried out. Salter Duck is geometrically similar to the duck beak invented by Stephen Salter. The incoming wave toward the nodding duck area will move the beak up and down. This up-down motion is used to rotate the gear transmission system and electric generator. In this research, various additional weight was mounted on the Salter Duck beak and its influence to the generated power was studied at various wave amplitude.The experimental results show that additional weight of 300gr and wave amplitude of 0.028m to the model of OWEH can produce maximum electric power of 19.01mWatt with maximum angular acceleration of 0.0427rad/s². Efficiency of the Salter Duck prototype is 56%.
