摘要
[目的]针对 15 MW级浮式风机,提出一种新型的Spar漂浮式风电平台设计方案,并对平台性能进行分析.[方法]基于势流理论对平台进行频域水动力计算,对不同浪向下的平台波浪力和运动响应特性进行研究;应用叶素动量法计算叶轮气动载荷并将其等效为风力系数,从而计算不同工况风浪流联合作用下的平台时域响应,同时对系泊缆的受力情况进行分析.[结果]结果显示,平台垂荡和纵摇在平台运动固有频率处出现了峰值点,且发生的位置均远离波浪的主要能量区域;在风浪流作用下,相较于工作工况,极限工况下的平台最大纵摇角略小,而最大纵荡和垂荡响应幅值以及最大系泊张力更大.[结论]研究证明新型Spar漂浮式风电平台具有良好的稳性和水动力性能,在设计环境载荷下,平台响应和系泊力均能满足要求,能够保障风力发电机组的安全性和稳定性.
Abstract
[Objectives]A new Spar-type floating wind turbine platform design scheme is proposed for a 15 MW floating wind turbine,and its performance is analyzed.[Methods]Based on potential flow theory,the frequency domain hydrodynamic calculation of the platform is carried out and the wave loads and motion response characteristics of the platform under different wave directions are analyzed.The blade element mo-mentum method is applied to calculate the aerodynamic load of the impeller and make it equivalent to the wind coefficient in order to calculate the time-domain response of the platform under the combined effect of wind,waves and currents under different working conditions,while also analyzing the force situation of the mooring lines.[Results]The results show that the heave,roll,and pitch of the platform have peak points at the natur-al frequency of its motion,and the positions of occurrence are all far from the main energy region of the waves.Under the action of wind,waves and currents,compared to the working conditions,the maximum pitch angle of the platform under extreme conditions is smaller,but the amplitude of maximum surge,heave and mooring tension are greater than the working conditions.[Conclusions]The newly designed Spar-type floating wind turbine platform has good stability and hydrodynamic performance.Under the designed environ-mental loads,its response and mooring force can meet the requirements of the specifications,ensuring the safety and stability of the wind turbine.
