South coast of Java has been highly preferred as the placement location of wave energy converter, due to its relatively huge energy potential. Furthermore, linear permanent magnet generator (LPMG) has became one of the popular methods to convert wave energy to electrical energy. Based on the shape of stator core, there are several models of LPMG. Quasi-flat LPMG is one of them, which has rectangular...
Conventional tubular linear permanent magnet generator (LPMG) is composed of permanent magnets which are placed in translator, and stator which is made of iron. However, this topology suffers from the relatively huge cogging force due to the interaction between the magnet and the iron, also a large core losses from hysteresis and eddy current. To reduce the force and the losses, modified design of...
This paper aimed to find out a model of 1 kWp flat-quasi linear permanent magnet generator (LPMG) for ocean wave power plant in South Java Ocean. First, a flat-quasi LPMG is modeled based on the wave characteristic at the placement site. The model was then simulated using finite element software of FEMM 4.2. Next, the model was optimized to find out the optimum output power and cogging force. The...
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...
