提出了一种应用于海上浮式风力机发电平台的减振与发电系统模型,系统结构由筒形浮子和直线发电机组成,利用浮子与发电机次级的直线运动实现平台的调谐减振,同时收集波浪能量进行发电,实现海上风能、波浪能组合发电模式。根据波浪基本理论构建系统浮子基本结构模型,计算浮子的压强分布和受力分布情况。通过改变浮子的附加质量进行调节浮子的纵向运动速度,使得电能转换效率达到最大,进而有效提高浮式风力机平台的稳定性和输出功率。

This paper presents a complementary energy generation system applied in floating offshore wind turbine platform,which consists of floater and linear generator.By using the linear movement of the floater and generator,the function of vibration and complementary energy generation can be obtained.Firstly,based on wave theory,the structure of floater is constructed and the pressure distribution and force distribution of the floater are calculated.By changing the additional mass of the floater,the stability and output efficiency of the system is improved.
