Design and Modelling of Wave Energy Converter and Power Take-Off System
Abstract
Ocean wave energy contains the largest energy density amongst all renewable energy. In Malaysia, the highest wave energy in the South China Sea is 12kW with maximum wave amplitude of 2 meters. This paper presents the design and modelling of wave energy converter and power take-off system that suitable for Malaysia in order to obtain the highest output of electrical power. A point absorber made up of a floating buoy connected by a fibre rope is used as wave energy converter. Linear permanent magnet generator has been used as the power-take-off system. This generator exploits directly the incoming sea wave vertical motion. This wave energy converter and power-take-off model have been developed and implement in Matlab. The model included wave energy, buoy water interaction, and linear generator. To extract highest wave energy, different parameters have been applied to the linear generator. Simulation results are presented showing three effects of three different parameters; winding coil turns, magnetic field strength and tooth width of the stator.
