摘 要：设计了一种基于电流控制的海洋波浪发电装置，利用双浮筒结构和永磁直线发电机直接地(直驱式)把海洋波浪能转换成电能的结构模型，采用基于Park变换理论的直线发电机电流控制方法，通过控制直线发电机的q轴电流，实现对海洋波浪发电装置的优化控制。通过海试实验结果分析表明，在自然状态下，海洋波浪发电装置的运行效率和稳定性受到海洋环境的约束，采用直线发电机电流控制的方法后，有效提高了该装置的运行效率和稳定性。

Abstract: An ocean wave energy generation device was designed and constructed. Double float bowl structure and direct drive permanent magnet linear generation were used to change the structural model of ocean wave energy into that of electric energy. The linear generation current control method based on Park conversion theory was adopted to realize optimal control for the ocean wave energy generation device by controlling linear generation q shaft current. Analysis of ocean wave experiment results show that under natural state, the operating efficiency and stability of the ocean wave energy generation device were constrained by marine environment. The adopted linear generation current control method improves the efficiency and stability of ocean wave energy generation device.
Key words: ocean wave energy generation; linear generation; current control; Park conversion
