Ocean wave energy is a high energy density and renewable resource. High power conversion rate is an advantage of linear generators to be the competitive candidates for ocean wave energy extraction system. In this paper, the feasibility of a wave energy extraction system by linear generator has been verified in an experimental flume. Besides, the analytical equations of heaving buoy oscillating in vertical direction are proposed, and the analytical equations are proved conveniently. What is more, the active power output of linear generator of wave energy extraction system in experimental flume is presented. The theoretical analysis and experimental results play a significant role for future wave energy extraction system progress in real ocean waves.

Establishing a theoretical model for Ocean Wave Energy Convertor in advance is a necessary step during studying the energy harvesting of ocean wave which can save the engineering cost and improve research efficiency. Since low energy conversion efficiency existed in wave energy convertor when capturing ocean wave energy, the mechanism of slotless Halbach linear generator which can optimize the magnetic field distribution of the generator is adopted as the secondary energy conversion devices to solve the problem. The magnetic vector potential theory is introduced to analysis the topology of Halbach linear generator, then expressions of the generator’s performance have been deduced. Hence, the analysis model of the Halbach linear generator has been settled. To obtain the global optimal solution, the simulated annealing algorithm has been used to slove that derived model. Then a series of linear generator’s design parameters are fixed, which include dimensions of permanent magnets and winding coils. The error of linear generator’s peak power between analytical solution results and simulation results is about 3.6%. The experiment result demonstrates that maximum output power of optimized Halbach linear generator reaches 570w.
