Abstract:

A direct-drive wave energy conversion system based on a three-phase permanent magnet tubular linear generator (PMTLG) and a heaving buoy is proposed to convert wave energy into electrical energy. Sufficient experimental methods are adopted to compare the computer simulations, the validity of which is verified by the experiment results from a wave tank laboratory. In the experiment, the motion curves of heaving buoy are with small fluctuations, mainly caused by the PMTLG's detent force. For the reduction of these small fluctuations and a maximum operational efficiency of the direct-drive wave energy conversion system, the PMTLG's detent force minimization technique and the heaving buoy optimization will be discussed. It is discovered that the operational efficiency of the direct-drive wave energy conversion system increases dramatically after optimization. The experiment and optimization results will provide useful reference for the future research on ocean wave energy conversion system.

中文摘要:

提出了一种基于三相永磁圆筒直线发电机和垂直浮筒的直驱式波浪能转换系统，此系统的功能是把波浪能转换成电能。在波浪水槽的试验过程中，该波浪能转换系统的仿真结果得到了试验结果的验证。试验过程中，垂直浮筒的运动曲线存在细小的波动性，其主要原因是由三相永磁圆筒直线发电机的定位力较大引起的。为了减少垂直浮筒运动的细小波动和提高直驱式波浪能转换系统的运行效率，文中阐述了三相永磁圆筒直线发电机定位力和垂直浮筒尺寸优化技术的方法。优化之后，直驱式波浪能转换系统的运行效率得到了显著提高。本文的试验和优化结果为未来的海洋波浪能转换系统的发展，提供了一定的参考价值。
