摘　　要：为提高漂浮式风力机平台稳定性,以Barge平台漂浮式风力机为研究对象,建立共用系泊系统3×3阵列Barge平台的漂浮式风电场。以叶素动量理论为基础,利用水动力学软件AQWA并结合有限元方法,对Barge平台漂浮式风电场和单个Barge平台在极限海况下考虑风波耦合作用的动态响应进行对比研究。结果表明,相较于单个Barge平台,风电场中各个平台的纵荡响应均小于单个Barge平台,位于两侧的各个平台产生不规则的横荡运动,但均较小;其次,Barge平台风电场的垂荡、纵摇及机舱加速度响应均优于单个Barge平台;同时,风电场中各平台表现出很好的首摇、横摇稳定性,波动幅度均未超过2°。研究结果验证了所建立的Barge平台漂浮式风电场的可行性,可为进一步开展新型漂浮式风电场研究提供理论依据。In order to improve the stability of the floating platform,this paper takes the Barge-type floating wind turbine as the research object,and establishes a floating wind farm with 3×3 array Barge of Common mooring system.Based on the blade element momentum theory,the dynamic response of Barge-type floating wind farm and a single Barge platform considering wind-wave coupling under extreme sea conditions are compared by using hydrodynamic software AQWA,combined with finite element method.The results show that the surge response of each platform in the wind farm is smaller than that of a single Barge platform,and irregular sway motion occurs on both sides of the wind farm,but they are also smaller;Secondly,the heave,pitch and nacelle acceleration responses of the Barge-type floating wind farm are better than that of single Barge platform;At the same time,all platforms in the wind farm show good yaw and roll stability,and the fluctuation range does not exceed 2 degrees.The research results validate the feasibility of establishing Barge-type floating wind farm,and provide theoretical basis for further research on new floating wind farm.
