Analytical design of sea wave energy power plant using tubular linear PM generator in southern coast of Yogyakarta, Indonesia

In this paper, sea wave power plant was designed to be applied in southern coast of Yogyakarta, Indonesia. The plant was expected to generate 700 Wp output. It had two components: tubular linear permanent magnet generator (TLPMG) and floater buoy. The buoy and the ocean wave were assumed moving continuously. By this condition, the generator was then simulated using finite element software of FEMM. Analytical calculation was performed later, which shows that the generator could generate induced voltage and output power up to 68.243 Vp and 674.811 Wp respectively. Furthermore, the generator only generated power at certain times, due to different length between the wave magnitude and translation path of the translator.
