摘　　要：为研究浮式风力机多平台阵列的动态响应特性,建立了基于OC3-Hywind Spar Buoy平台的NREL 5 MW浮式风力机整机模型,根据辐射/绕射理论方法分别研究并比较了单平台、1×5线性排布和3×3方阵排布的多平台动态响应特性.结果表明:浮式风力机Spar平台在纵荡、垂荡和纵摇方向的响应均集中在低频波浪阶段;1×5线性排布的多平台纵荡位移响应均低于单平台,共用系泊系统有效抑制了平台的纵荡位移响应,但是对垂荡位移、纵摇偏转角响应影响不大;3×3方阵排布位于两侧的平台存在较大的横荡位移响应,但纵荡位移响应均小于单平台,位于中间位置的平台纵荡位移响应大于单平台,但横荡位移响应几乎可以忽略不计;3×3方阵排布中心位置和顶点处的平台垂荡位移、纵摇偏转角响应小于单平台,其余平台垂荡位移、纵摇偏转角响应没有受到明显抑制.To investigate the dynamic response of wind turbine platform matrix, models were established based on OC3-Hywind Spar Buoy platform for NREL 5 MW wind turbine, with which, a comparison was carried out on dynamic response characteristics of floating platforms respectively in single, 1×5 linear and 3×3 square arrangement applying radiation and diffraction theory. Results show that the surge, heave and pitch response of Spar platform all appear in the range of low frequency waves; the 1 ×5 linearly arranged platforms have lower surge response than single platform, because the sharing mooring reduces the surge response, which does not have obvious effect on the heave and pitch response~ in terms of 3×3 squarely arranged platforms, the platforms located on sides have higher swaying but smaller heave response than single platform, while the platforms in middle area have higher surging and negligible swaying response; in terms of 3×3 squarely arranged platforms, the heave and pitch response of platforms in middle area and at vertices are lower than single platform, and the response of rest platforms are not significantly suppressed.
