Performance Analysis of Wave-energy Permanent Magnet Linear Generator

Wave energy as a kind of clean energy, in the past proposed a variety of wave energy development program, most of the conversion device between the wave energy and the generator, but this efficiency is low, while the cost is high. This paper presents a cylindrical permanent magnet linear generator which can convert wave energy directly into electric energy. The structure and modeling of the generator are described in detail. By using the finite element analysis software of electromagnetic field, the generator is simulated, and its no-load and load characteristics are studied, and its performance is analyzed in wave environment. The simulation results can guide the theoretical research of cylindrical permanent magnet linear generator.
