对一种基于移动直线发电机的海浪能-电能转换装置的技术可行性和性能特点进行了评估。加州大学伯克利分校的设计包括一个圆柱形浮子，充当转子，驱动由两组缠绕线圈组成的定子。这种装置在波浪中的性能取决于浮子的流体动力学，浮子的运动与发电机的电磁特性有很强的耦合。建立了数学模型，以揭示影响设计效率的关键障碍。还构建了一个工作物理单元。线性发电机首先在干燥的环境中进行测试，以量化其性能。然后，完整的物理浮子和发电机系统在带有计算机控制的造波机的波浪水箱中进行测试。将测量结果与理论预测进行比较，以评估设计的可行性和未来的改进方向。版权所有©2010，ASME
This paper evaluates the technical feasibility and performance characteristics of an ocean-wave energy to electrical energy conversion device that is based on a moving linear generator. The UC-Berkeley design consists of a cylindrical floater, acting as a rotor, which drives a stator consisting of two banks of wound coils. The performance of such a device in waves depends on the hydrodynamics of the floater, the motion of which is strongly coupled to the electromagnetic properties of the generator. Mathematical models are developed to reveal the critical hurdles that can affect the efficiency of the design. A working physical unit is also constructed. The linear generator is first tested in a dry environment to quantify its performance. The complete physical floater and generator system is then tested in a wave tank with a computer-controlled wavemaker. Measurements are compared with theoretical predictions to allow an assessment of the viability of the design and future directions for improvements.Copyright © 2010 by ASME
