摘要
能量转换器(PTO)是波浪能发电装置(WEC)中非常关键的单元。介绍了一种采用滚珠丝杠结构和机械运动整流器(MMR)来提高能量转换性能的新型能量俘获装置。PTO将海浪的双向振荡运动转化为发电机的单向旋转。详细阐述了PTO设计和工作原理,建立了PTO的动力学模型,并解释了MMR齿轮箱中一种特殊的运作方式;利用ADAMS软件对波浪能发电系统进行动力学仿真分析,模拟波浪的双向输入转换为发电机的单向电压输出的过程。研究结果验证了单向离合器在能量转换过程中的作用和系统的可靠性,PTO独特的运作方式可使系统获得比较稳定的功率输出。
Power take-off(PTO)is a core unit of the wave energy converter(WEC).A novel mechanical PTO using a ball screw mechanism and a mechanical motion rectifier(MMR)to improve the energy conversion performance was introduced.PTO can convert the two-way oscillatory motion of ocean waves into one-way rotation of generators.The detailed design and working principle of the PTO were explicitly explained.The mechanical dynamics model of PTO was established.The unique motion in operation was explained.A dynamic simulation of WEC was performed in ADAMS.Results show that the significance of one-way clutch in energy conversion and the reliability of the system.And according to the unique operation mode of PTO,the system can obtain relatively stable power output.
