Abstract

The energy density of wave power is higher than some renewable energy sources such as wind and solar energy. However, because waves have an irregular reciprocating motion, it is difficult to convert wave power into electricity, and this has restricted the widespread use of wave power. In this paper, a new mechanism to convert wave power into electricity is proposed. It is referred to as a “direct-link” mechanism consisting of a buoy, rack, and pinion. Because of its simple load transfer path, it is expected that the energy conversion efficiency is higher than that of the usual wave power conversion systems. Surface permanent magnet synchronous generators for the proposed system are designed with different numbers of poles. The electrical output characteristics considering the appearance probability of the waves in Shionomisaki are calculated by a dynamic simulation. It is shown that the conversion efficiency of the proposed system is remarkably improved from that of a conventional system.

考虑波浪出现概率的直连式波浪发电系统发电机设计及特性

波浪能的能量密度高于一些可再生能源，如风能和太阳能。然而，由于波浪具有不规则的往复运动，因此很难将波浪能转化为电能，这就限制了波浪能的广泛使用。本文提出了一种将波浪能转化为电能的新机制。它被称为由浮标、齿条和小齿轮组成的“直连”机构。由于其负荷传递路径简单，其能量转换效率有望高于一般的波浪能转换系统。设计了不同磁极数的表面永磁同步发电机。通过动态仿真计算了盐井县在考虑波出现概率的情况下的电输出特性。结果表明，该系统的转换效率比传统系统有显著提高。
