摘要: 提出一种在深海海底直接利用海水的压力进行发电的能量供给技术,并将开关液压源理论应用于其海水液压马达的驱动控制,实现了流量的复用以及输出转矩与负载的自动适应,大幅度提高能量的转换效率。在此基础上,提出相应的输出电压控制方法,并进行了理论分析和仿真研究。结果表明,该系统具有良好的抗干扰能力,但响应速度相对较慢。

Abstract: A new power supply technique, in which electricity is generated from seawater pressure at deep sea bottom directly, is put forward. Switchmode hydraulic power supply theory is applied in the driving and control of its seawater hydraulic motor so that its flow rate could be duplicated used and its output torque could adapt the load automatically. Energy converting efficiency is increased considerably. Based on these, correspondent output voltage control method is put forward. Theoretical analyses and simulations show that its anti-disturbance ability is good, but its response is relatively slow.
