摘要
通过对直驱式波浪发电系统的功率捕获优化方法进行研究,文中提出一种基于直线发电机的状态切换控制方法。即基于直驱式波浪发电系统中直线发电机在空载状态的速度比发电状态时的速度高的特点,控制直线发电机使其在空载状态和发电状态之间进行切换,从而提高发电机在发电状态时的运行速度,最终实现捕获功率的进一步提高。与其他功率捕获优化方法进行对比的结果表明,文中提出的方法在功率捕获上表现出优异的性能。
Based on the research of the power capture optimization method for the direct-drive wave power generation system,a state switching control method based on a linear generator was proposed in this paper.Based on the characteristic that the speed of the linear generator in the no-load state is higher than that in the power generation state,the linear generator is controlled to switch between the no-load state and the power generation state,thereby increasing the speed of the linear generator in the power generation state.Therefore,the captured power is further improved.The results show that,compared with other power capture optimization methods,the proposed method has excellent performance in power capture.
