Design of energy harvesting system for low-power ocean current power generation

针对我国大部分海域处于低流速区的情况,设计了针对低流速的小功率海流能发电能量收集系统,实现了发电机能量捕获、电能存储及负载供电控制和数据信息的采集记录。通过调节DC-DC电路输出电流,用最大功率跟踪(Maximum Power Point Tracking,MPPT)的方法,避免了传统调节方式存在对控制要求高,效率低的弊端,提高了系统的稳定性和效率。实验测试表明,系统功能满足设计要求,具有一定的应用参考价值。

In view of the fact that most of China’s sea areas are in low-velocity areas,a low-power lowcurrent sea-current power generation energy collection system is designed to realize generator energy capture,energy storage,load power supply control,and data information collection records.By adjusting the output current of the DC-DC circuit for Maximum Power Point Tracking(MPPT),the traditional control method has the disadvantages of high control requirements and low efficiency,and improves system stability and efficiency.Experimental tests show that the system functions meet the design requirements and have certain application reference value.
