Design And Power Generation Performance Analysis of A Rim-Driven Wave Energy Generator

Abstract Wave energy exploitation is getting more attention from researchers Many types of devices that can convert wave energy into electricity have been designed. At present, engineers and scientists are researching how to make a simple and efficient wave energy capture device. This paper explored the rim-driven generator. In a rim-driven wave energy generator, the rotor blade could harvest kinetic energy of wave motions. The blade is inside of the generator and the gap between the stator and the rotor is water-filled. This structure could improve the compactness and reliability of the wave energy generator. The paper studied the influence of the arrangement of the blade and the structure of the generator on the performance of the generator. Analytical models were designed to obtain generator’s performance. The result could optimize the design of generator and improve the energy conversion efficiency.
