摘要
近几年提出了多种对波浪能进行开发的方案,大多都是在波浪能和发电机之间加入转化装置,这样效率低,成本较高。该文提出了Halbach磁体结构的圆筒型直线发电机可以将波浪能直接转化为电能。详细阐述了该发电机的结构和工作原理,并且基于Maxwell 2D对于发电机进行仿真,得到了磁场分布图、空载和负载电压的波形,仿真结果可以指导Halbach磁体结构的圆筒型直线发电机的理论研究。
Wave energy is a new clean energy.In recent years,several approaches to extract wave energy have been presented.Most of them low efficiency and high cost as introducing a mechanical conversion device between the waves and the electromagnetic generator,a novel generator was proposed to produce electric energy directly based on the sea wave＇s energy.The structure and working principle of the generator were expatiated in detail,the distribution figure of magnetic field and waveforms both load and no load were obtained by simulating in finite element software Maxwell 2D.The simulation results can be used for theoretical study of tubular linear generator（TLG） with halbach magnet array.
