摘　　要：为研究不同海上风力机漂浮式风电场平台风浪流联合作用下动态响应,分别建立基于OC3-Hywind Spar与ITI Energy Barge平台漂浮式风力机的2×2阵列漂浮式风电场,结合辐射/绕射理论与有限元方法,使用海洋工程软件AQWA及风力机仿真软件FAST分别进行水动力学与气动载荷计算,分析2种漂浮式风电场平台时频响应特性。结果表明:Spar与Barge平台频域响应均集中在2.00 rad/s以下低频区域,在2种风电场中,Spar风电场各平台在垂荡、纵摇、横摇、艏摇4自由度及机舱振动加速度上稳定性较好;风电场中平台横荡、纵荡及机舱振动加速度大小与其在风电场中所处位置有关。In order to study the dynamic response of different floating wind farm platforms with offshore wind turbine under the combined action of wind,wave and current,2×2 array floating wind farms based on OC3-Hywind Spar and ITI Energy Barge platform are established respectively.Combined with radiation and diffraction theory and finite element method,the hydrodynamic and aerodynamic loads are calculated by ocean engineering software AQWA and wind turbine simulation software FAST respectively,and the time-frequency response characteristics of the two floating wind farm platforms are analyzed.The results show that the frequency domain responses of both Spar and Barge platforms are concentrated in the low-frequency region below 2.00 rad/s.Among the two types of wind farms,the platforms of Spar wind farm have better stability in heave,pitch,roll,yaw four degrees of freedom and nacelle vibration acceleration.The magnitude of platform sway,surge and nacelle vibration acceleration are related to their position in the wind farm.
