Analysis of Performance of Novel Permanent Magnet Tubular Linear Generator for Wave Energy Converters

波浪能是一种清洁的新能源,近几年提出的多种开发波浪能的方案,大多都在波浪能和发电机之间加入转化装置,这样效率低、成本较高。提出了圆筒型永磁直线发电机可以将波浪能直接转化为电能,详细阐述了该发电机的结构和工作原理。该发电机内的电磁场具有轴对称性,故将其三维电磁场简化为二维场。运用电磁场有限元分析软件对发电机进行仿真,并研究其特性,如磁场分布、空载反电动势、绕组磁链、电磁力和绕组电感等,仿真结果可以指导圆筒型永磁直线发电机的理论研究。

As a clean energy, wave energy is popular in recent years. Whereas, most of the wave energy devices developed use the conversion system to utilize the wave energy, thus the efficiency is too low. The novel permanent magnet tubular linear generator proposed would convert the wave energy to electricity directly. The structure and principle of the generator was introduced detailedly. The analysis software was used to simulate the working of the generator. The simulation result is helpful for the research of permanent magnet tubular linear generator.
