基于平均功率估算的直驱海浪发电最大功率点跟踪控制方法
Maximum Power Point-tracking Control Method for Direct-drive Wave Energy Generation Based on Average Power Estimation
摘要
Abstract
This paper analyzes the mechanical model of direct‐drive wave energy converters under the effect of regular sea waves . With the electromagnetic force of the linear generator equivalent to the linear combination of velocity and displacement as the control method , the characteristic curve of the average output power of the system under the control variables is obtained . The mountain‐climbing method can achieve maximum power point‐tracking ( MPPT ) control . For the key issue average power measurement , an average power measuring method based on period judgment is proposed . To avoid errors in estimation in the transient process , a method for judging whether the system is in a steady state is included . Experimental results have verified the validity of the proposed method that has improved its adaptability to the wave period variation and the tracking speed of the MPPT control .关键词
