绷紧式系泊浮式风机动力响应及系泊优化

Dynamic Responses and Mooring Optimization of Floating Wind Turbine Using Taut-Wire Mooring System

针对OC3 Hywind Spar式浮式风机,建立风机基础模型,利用FAST软件与ANSYS AQWA软件进行空气动力与水动力耦合分析,研究采用绷紧式系泊的浮式风机的运动响应。对比绷紧式与悬链式系泊在相同水平跨距、不同水平跨距和不同系泊点位置时浮式风机的运动响应,选取最优系泊布置方式。结果表明:与悬链式系泊相比,绷紧式系泊在满足浮式风机使用要求的同时,能够显著减小系泊的水平跨距。

Taken the OC3 Hywind Spar type floating wind turbine as the study object,the model of the wind turbine foundation is established.The aerodynamic hydrodynamic coupling time domain analysis method is used to analyze the dynamic responses using taut wire mooring system by FAST and ANSYS AQWA software.A comparison between the dynamic responses of the catenary mooring system and taut wire mooring system on the same horizontal span is conducted.By changing the horizontal span and the location of mooring point,the optimization layout of the mooring system is proposed.The results show that compared with the catenary mooring,the taut wire mooring system needs smaller horizontal span while meeting the requirements of the floating wind turbine.
