摘　　要：波浪对漂浮式潮流能水轮机的水动力性能具有重要的影响,论文采用切片理论建立和三维水轮机无辐射运动时立轴潮流水轮机水动力载荷近似计算公式,计算分析了浪流同向条件下,海能1号2×150 k W漂浮式潮流电站两叶片固定偏角立轴水轮机在波浪中的水动力载荷。计算结果表明,波浪中潮流水轮机水动力具有双频特性;水轮机工作工况下,每增加1 m波高,水轮机极限载荷增加27%,在相同波高条件下,主轴极限载荷随波长的增加而增大。Sea waves can significantly affect the hydrodynamic performance of floating vertical axis turbine（VAT）.An approximate formula based on the slender body theory is derived to calculate the hydrodynamic load of 3D VAT. The hydrodynamic loads of the fixed-blade VAT with two blades installed on the ＂Haineng-1＂ floating tidal current power station are calculated at the case of the same direction with currents and waves. The numerical results show that the hydrodynamic loads on turbine axis have two-period properties. On the working condition of the turbine, the maximum load increases by 27% when the wave height rises by 1 m. At the same wave height and working conditions, the maximum loads of the main axis increase with increasing wave length.
