摘要
本文研究过渡水深60 m水深处风浪偏向角对浮式风机系统动力响应的影响,以OOstar浮式基础为雏形,利用丹麦技术大学(Danmarks Tekniske Universitet,DTU)DTU-10 MW风机,据风浪联合分布概率设计了计算工况,进行了浮式风机系统的时域响应模拟,分析了风浪偏向角对浮式风机系统动力响应的影响。研究表明:当风速低于额定风速时,风浪偏向角在±30°范围内概率较高,此时波高较小,风浪偏向角对浮式风机运动影响较小;高风速时,风浪偏向角会引起浮式风机横向运动增加较多,需要考虑其影响;浮式风机气动载荷和系缆力极值受风浪偏向角的影响较小。针对风浪夹角对浮式风机响应影响的研究为海上浮式风机设计提供了一定的参考。
This paper studies the influence of angel between wind and waves on dynamic response of floating offshore wind turbine at an intermediate water depth of 60 meters.Based on OOstar floating foundation,using DTU(Danmarks Tekniske Universitet)10 MW turbine,this paper designs calculation condition,and the time domain response of the floating offshore wind turbines is simulated,and the influence of angle between wind and waves on the dynamic response of the floating offshore wind turbines is analyzed according to the joint distribution probability of wind and wave.The results show that when the wind speed is less than the rated wind speed,the angle between the wind and waves is mainly distributed in the range of±30°,at this time,the wave height is small,the impact on the floating offshore wind turbine dynamic response is weak;in the case of high wind speeds,there is an angle between the wind and waves will cause the wind turbine the lateral response increases more,so there is no need to consider the existence of the angle between the wind and waves of the conditions;The aerodynamic load and mooring force of floating offshore wind turbines are less affected by the angle between wind and waves.In this paper,the study on the effect of wind and wave angle on the response of floating wind turbines provides some reference for the design of floating wind turbines.
