摘要
设计出一种蛇形波浪能采集系统。系统由圆柱浮筒连接构成,浮筒中交替放置永磁体和软磁体。浮筒随着波浪上下浮动,引起缠绕在软磁体上线圈中磁通量的改变,感应出电能。针对黄海海域建立出海浪数学模型,据此设计结构参数。应用Ansys对系统仿真计算,单个浮筒的平均功率约2.36 kW,能量采集效率约18.9%。
A wave energy harvesting system that composed by cylindrical buoys is designed. Permanent magnet and soft magnet are put alternatively into the buoys. And coils are put surrounding the soft magnet. The buoys mov-ing with wave will cause voltage in the coils according to Faraday＇s law of electromagnetic induction. The software is used, Ansys, to finish the simulation of the system. And calculation result shows each buoy with soft magnetcould generate 2.36 kW power, and the efficiency of the system could reach to 18.9%.
