摘要/Abstract

摘要： 能量俘获系统与能量转换系统构成整个波浪能装置，其中能量转换系统是波浪能利用的关键环节。设计一套适用于漂浮式波浪能装置上的液压式能量转换系统，包括液压缸、液压马达、蓄能稳压系统、液压控制系统及发电机。液压控制系统中采用特制的“液压自治控制系统”，用于根据发电许可最大压力与最小压力控制液压系统能量释放与储蓄动作，并将最大压力提高到23 MPa，最小压力提高到9 MPa。大量试验数据表明，压力提高后的液压转换系统较之以前的液压系统在效率和可靠性方面有明显的改进，对波浪能海况试验样机研发意义重大。

Abstract: Wave energy converter (WEC) includes an energy harvesting system and a power take-off (PTO). The PTO of a floating WEC is the key that converts wave energy into other forms. A set of hydraulic PTO, which is designed for the floating WECs, includes hydraulic cylinders，hydraulic motors, a pressure-maintaining energy storage system, a hydraulic control system and a generator. The hydraulic control system adopts a special “hydraulic self-control system” to control the hydraulic system to release energy under the maximum pressure, or to storage energy under the minimum pressure. During experiments, the maximum pressure is enhanced to 23 MPa, the minimum one to 9 MPa. Comparison between the new hydraulic system and the previous one, quite a few experiments’ data show that the new has evidently improved in efficiency and reliability. The result has great significance in the research and development of WEC prototype.

Key words: Conversion efficiency, Hydraulic control, Hydraulic power take-off, Second transfers
