Subsection control strategy of oscillating buoy wave power generation system

针对波浪发电效率低问题,文章提出了一种振荡浮子式波浪发电分段控制策略。在考虑发电机效率的前提下,提出低速空载储能运行与高速带载发电运行相结合,以提高发电量。在Matlab/Simulink环境下搭建模型进行仿真计算,分析了切入速度和切出速度对输出功率的影响,并在机电模拟实验平台上进行了控制试验验证。仿真与试验结果表明,采用该方法提高了波浪发电的平均输出功率。

For the low efficiency of wave energy conversion, this article presents a subsection control strategy of oscillating buoy wave power generation. Considering the efficiency of liner generator, the control strategy combining low-speed no-load energy storage operation with high-speed on-load power generation operation is proposed. To research the impact of conversion speed on output power, a wave power generation model is built based on Matlab/Simulink simulation platform. What’s more, a experiment is carried out on the electromechanical simulation experiment platform. The simulation and experiment show that this strategy increases the average output power of wave power generation.
