海洋资料浮标波能供电装置数值模拟研究

Numerical simulation of wave energy convertor of ocean data buoy

海洋资料浮标的电源补给问题是亟待解决的关键技术之一。本文以浮标现有技术参数为基础,通过数值模拟研究以浮标标体作为能量吸收系统,传统齿轮齿条形式作为能量输出系统,永磁发电机配合滤波整流稳压模块作为电力输出系统的海洋资料浮标波浪能供电装置的可行性。计算结果表明,不考虑各阻尼,浮标体在波浪作用下可满足高转速、低扭矩的500 W三相交流永磁同步发电机的装机容量,同时理论计算发电机的输出电压可达到海洋资料浮标蓄电池14 V的充电要求。

Power supply is one of the key issues in ocean data buoy. We address the feasibility of wave energy convertor of ocean data buoy with buoy body as wave energy absorption system, gear and rack as power take-off system and permanent magnet wind turbine and rectifier voltage regulator module as power output system, based on numerical simulation and the existing technical parameters of ocean data buoy. Analysis of calculation results shows that wave buoy body can satisfy installed capacity of 500 W three-phase AC permanent magnet synchronous generator if no damping. Generator output voltage of theoretical calculation can also meet the charging requirement of ocean data buoy battery of 14 V.
