为探究机组大型化对张力腿型浮式风力机的影响
以DTU 10 MW和NREL 5 MW风力机为研究对象
建立风力机系统耦合计算模型
对其在典型海况下的响应特性进行时域数值仿真
研究机组大型化产生的影响。结果表明
上部风力机大型化引起浮式基础运动响应放大
不同自由度运动耦合现象突出
运动频率成分更加复杂。在额定海况下
相对于5 MW机型
10 MW浮式风力机纵荡运动均值增大
垂荡运动平衡位置发生明显改变
纵摇运动剧烈程度增加
且基础纵摇运动出现更为复杂的谐振特性。同时
10 MW风力机叶片旋转平面外变形均值、平面内变形极值都较5 MW机型有所增加。此外
10 MW浮式风力机叶片变形对风速改变的敏感度更高。
In order to study the effect of large scale wind turbine in tension leg type FOWT (Floating Offshore Wind Turbine)
the DTU 10 MW and NREL 5 MW wind turbines are taken as the research objects
and the coupling model of wind turbine-tower-floating foundation-mooring system is established. Time domain simulation is carried out and the influence of large scale FOWT is studied by comparing the difference in the floating foundation motion and blade deformation results. The results show that the large scale wind turbine leads to the increase of the motion of the floating foundation and makes the coupling effect more conspicuous and the frequency component more complex. Under the rated environmental condition
compared with the 5 MW model
the mean value of the surge motion of the 10 MW floating wind turbine increases by 47.2%
and the equilibrium position of the heave motion changes significantly. The intensity of the pitch motion is 1.7 times that of the former
and the pitch motion of the foundation exhibits more complex resonance characteristics. Meanwhile
the average out-of-plane deformation of the large scale wind turbine blade is 1.6 times that of the 5 MW wind turbine
and the in-plane deformation intensity is 1.8 times that of the 5 MW model. In addition
the blade deformation of 10 MW floating wind turbine is more sensitive to change of wind speed.
