| 摘 要： | 为研究混合式平台漂浮式风电场平台动态响应,分别建立基于Spar和Barge平台的漂浮式风力机整机模型,采用链接悬链线和固定悬链线将其链接以建立2×2阵列漂浮式风电场。采用叶素动量理论计算风载荷,通过辐射/绕射理论求解波浪载荷,采用水动力学软件AQWA研究风波载荷作用下漂浮式风电场平台的动态响应。针对Spar和Barge平台尺度大小不同导致系泊系统不对称引起的Spar平台横摇和艏摇响应较大问题,提出"依照尺度最大平台正交布置链接悬链线"的漂浮式风电场系泊系统布置准则。为验证所提出的系泊系统布置准则的可行性,对比研究系泊系统正交化前后漂浮式风电场平台的动态响应。结果表明,在极限海况下,系泊系统的正交化布置可减小Spar平台横荡响应,但一定程度会增加纵荡响应;而系泊系统正交化与否对漂浮式风电场平台垂荡、纵摇响应和机舱加速度影响较小。此外,正交化布置的系泊系统可显著减小Spar平台横摇和艏摇响应、Barge平台艏摇响应,而Barge平台横摇响应几乎不受影响。

| Abstract: | In order to study the dynamic response of platforms in hybrid platform floating wind farm,the model of the floating wind turbine based on the Spar and Barge platform is established respectively,and the 2×2 array floating wind farm is built by linked catenary and fixed catenary.The wind load is calculated by the blade element momentum theory,the wave load is calculated by the radiation/diffraction theory,and the dynamic response of the floating wind farm platform is studied by the hydrodynamic software AQWA.In view of the large roll and yaw response of the Spar platform caused by the asymmetry of mooring system due to the different dimensions of platforms,a mooring system layout criterion of floating wind farm is proposed,which is based on the"orthogonal arrangement of linked catenary according to the largest scale platform".In order to verify the feasibility of the proposed mooring system layout criteria,the dynamic response of the floating wind farm platforms before and after the orthogonalization of the mooring system is compared.The results show that the orthogonal arrangement of mooring system can reduce the sway response of the Spar platform,but increase the surge response to a certain extent,while the orthogonal arrangement of mooring system has little effect on the heave,pitch response and nacelle acceleration of floating wind farm platform.In addition,the orthogonal mooring system can significantly reduce the roll and yaw response of the Spar platform and the yaw response of the Barge platform,while the roll response of the Barge platform is almost unaffected. |
