Design and experiment of a series connection floating two-body direct-drive wave energy generation system
Considering the inconvenient installation and the poor ability to capture wave energy in the traditional direct-drive wave energy converter(DD-WEC),a series connection floating two-body DD-WEC is proposed in this paper.Two rectangular bodies of the WEC float horizontally in the waves bodies and both capture the wave energy.The primary and secondary of the Halbach array permanent magnet linear generator(HPMLG)are respectively installed on the lateral surface between the two floating bodies.Because both floating bodies capture wave energy,the ability of the WEC to capture wave energy is improved,and the structure of the WEC is simple and easy to manufacture and maintain.Then,the prototype of the two-body DD-WEC is manufactured and tested in the wave tank in this paper.The experimental results show that in the case with the wave height of 16 cm and the draft of 16 cm,the average generated power of the prototype reaches the maximum value of 6.54 W at the wave period of 1.8 s,when the wave period ranges from 1.2 s to 2.4 s.Finally,the two-body DD-WEC prototype is compared with the single-body DD-WEC prototype.The results show that the average power output of the two-body DD-WEC prototype is always higher than that of the single-body DD-WEC prototype in a large range of wave period.
