摘要
针对无人水下航行器在水下长时连续工作对能源的需求,提出了一种由两级转换系统构成的海洋动能发电装置方案,该装置可直接将海洋动能传递给发电机,去掉了中间的能量传递环节,可有效减小结构体积、提高系统的转换效率。基于永磁发电机基本原理和刚体绕定轴转动定律,建立了飞轮动能与电机输出电压的关系模型,结合项目组研制的海洋动能发电装置试验样机,经过仿真表明,所提出的模型方法是合理可行的,为后续开展分析不同海况下晃动动能发电装置的发电效率提供了理论基础。
For dealing with the energy demand of UUV（ unmanned underwater vehicle） for long continuous work, the kinetic energy generate electricity scheme of the ocean energy is established, which only consists of two conversion systems. The scheme can pass directly the ocean kinetic energy to the generator, which removes the middle part of the energy transfer, so it can effectively reduce the structural volume and improve conversion efficiency of the system. Based on the principles of permanent magnet generator and laws of rigid body rotation around a fixed axis, the relational model of flywheel kinetic energy and the motor output is proposed. Then com- bining with the test prototype, simulation results show that the model proposed is reasonable and feasible, the theoretical basis is provided for subsequent analysis of generate electricity efficiency under different sea conditions.
