HARVESTING WAVE ENERGY WITH LINEAR GENERATOR

Abstrak

Ocean wave energy has great potential to be converted into electrical energy. In recent years researchers have focused on harvesting ocean wave energy into electrical energy with several technology models, one of the technologies used is to use linear generators. Generator placement becomes a separate problem when harvesting wave energy. This paper examines the placement of linear generators in a vertical position to optimize wave energy conversion under conditions of non-constant seawater wave height. The experimental research method uses a linear generator design mounted vertically with a float ball positioned flush with the water surface, waves are generated in a simulation pond to harvest wave energy. The results showed that the vertical installation position of the linear generator increased the wave energy conversion by 8.36% with a wave period of 1,22 seconds. The increase in efficiency is due to an increase in the step length of the magnetic shaft and the area of the linear generator stator coil that is subjected to electrical induction.
