Research on Performance of Single Pendulum Permanent Magnet Direct-Drive Wave Energy Converter
In order to solve the problem of long-term energy supply for marine instruments,based on the electromagnetic proper-ties of permanent magnet materials,combined with a pendulum energy capture mechanism that is easy to vibrate,a permanent magnet wave energy power generation device combined with a small-volume spherical buoy is proposed.The power generation principle and design scheme of the device are discussed in detail,and the motion model of the device under wave excitation is de-duced.Relying on AQWA and Maxwell to carry out joint simulation and optimize the parameters of the device.The final simula-tion results show that the pendulum performs a reciprocating motion with a period of Tp=2s and an amplitude of Ap=15°under the wave condition where the wave incidence angle β=0°,the wave period T=3.5s,and the wave height H=0.6m.The maximum in-duced electromotive force generated by the single-phase winding can reach 27.7V,and the best output power is 2.07W,which can effectively meet the power supply requirements of marine instruments.
