为实现海上风力发电平台工作状态的准确预报,本文采用有限元软件建立浮式风力发电平台三维模型,完全时域耦合分析在不规则波作用下,浮式风力发电平台动力响应特性。通过时域结果对比分析可知,在风浪流同向作用下,浮式风力发电平台的运动响应幅值及系泊缆索顶端张力最大。通过运动响应时间历程曲线可知,横荡运动和横摇运动表现为低频特性,垂荡运动表现为波频特性,以上研究成果可为浮式风力发电机的优化设计提供一定的指导,并可为将来的相关试验提供一定参考。
To achieve the precise research of operative mode of floating wind platform, this paper create the three-dimensional model, give the analysis of dynamic response characteristics of floating wind platform in irregular waves by fully time domain coupled analysis. The motion of floating wind platform and the top tension of mooring lines are the maximum in the same direction of current and wave by the time domain results of comparative analysis. The results show that the motion of sway and roll put up the characteristics of low frequency, the motion of heave show the characteristics of low frequency, the above results can provide some guidance for the optimized design of floating wind turbines and supply the reference for related tests in the future.
