With the continuous development of society and economy, people’s demand for electric energy is increasing. The low-carbon and energy-saving technologies of renewable energy especially wave energy have become the focus of current researches. Considering the increasingly serious energy problems, a wave energy converter (WEC) is proposed based on Halbach permanent magnetic array, which increases the output performance. The equivalent magnetic circuit model of the WEC is established. The static magnetic field modeling and structural parameters optimal permanent of the WEC are performed on this theoretical. Theoretical studies have found that the optimal permanent magnet thickness ratios for Halbach permanent magnet array structures is 0.6, and the ratio of permanent magnet to coil radial ratio is 0.7. The coil winding form and rectifying circuit of the WEC were designed. The WEC equivalent magnetic circuit model was verified by COMSOL Multiphysics finite element software, and the open circuit voltages of WEC was obtained. If the WEC moves at a speed of 0.1 m/s, the coil voltage can reach about 113 V after simulation. According to the testing requirements of the WEC, a test platform was built. The Halbach permanent magnet array structures greatly enhances the wave energy collection of WEC.

基于哈尔巴赫永磁阵列的波能转换器的设计与性能测试

随着社会经济的不断发展，人们对电能的需求越来越大。可再生能源特别是波浪能的低碳节能技术已成为当前研究的重点。考虑到日益严重的能源问题，提出了一种基于Halbach永磁阵列的波能转换器（WEC），可提高输出性能。建立了WEC的等效磁路模型。以此理论为基础进行了WEC的静磁场建模和结构参数的最佳永久性。理论研究发现，Halbach永磁阵列结构的最佳永磁体厚度比为0.6，永磁体与线圈径向之比为0.7。设计了WEC的线圈绕组形式和整流电路。用COMSOL Multiphysics有限元软件对WEC等效磁路模型进行了验证，得出WEC的开路电压。如果WEC以0.1 m / s的速度移动，则仿真后线圈电压可以达到约113V。根据WEC的测试要求，搭建了测试平台。Halbach永磁体阵列结构大大增强了WEC的波能收集能力。
