Power Generation from Wave Energy using Floating Device

Abstract

In Malaysia, there are a lot of islands that use diesel generators to generate electricity. This is because of expensive power connection from the grid system. However, when using the generators, it contributes to high pricing of diesel and difficult to distribute the supply to each island. Furthermore, the source is not sustainable and can affect environment due to carbon monoxide and carbon dioxide from the generators. Therefore, renewable energy sources have becomes an alternative solution for these problems. The advantages of using renewable energy are it is sustainable resources, produce clean energy, and low operating cost. One of the possible renewable energy sources is sea wave energy. There are few techniques to generate power from wave energy which are oscillating water column (OWC), tapered channel (TAPCHAN) and floating device. From this project, the technique of floating device (linear generator) was chosen because this technique is more affective and only requires small area of construction. SOLIDWORKS software was used to design the prototype for this project. From the result, the designed model can produce about 13mV. The effect of wave heights, number of turns, and diameter of coil wire were analyzed.
