摘要

浮式风机变桨故障后紧急顺桨停机可能会引起风机传动系统、机舱设备、塔筒和浮式基础荷载和弯矩的巨大波动。本文采用空气动力-水动力-控制系统-结构动力全耦合非线性方法模拟了不同海况下的全潜式浮式风机变桨系统故障，分析了风机低速轴弯矩、机舱加速度、塔筒弯矩和浮式基础的运动响应变化。结果表明，在变桨故障后紧急顺桨停机工况下，风机系统内部所受荷载和弯矩与正常运行相比有明显增加，在优化控制方法后，即变桨故障后高速轴刹车并减速顺桨，风机系统内部增加的荷载和弯矩得到有效缓解。

Abstract

Floating wind turbine blade pitch fault followed by emergency shutdown may cause large loads fluctuation in wind turbine drivetrain,nacelle,tower,and support structures.Coupled non-linear aero-hydro-servo-elastic simulations of a submersible platform supported floating wind turbine were carried out for blade pitch fault cases over a range of environmental conditions.The loads and moments in low-speed shaft,nacelle,tow-top,tow-base and the motions of floating platform were investigated.The results show that loads and moments in the wind turbine system increase significantly in blade pitch fault followed by emergency shutdown condition comparing to the normal operation phase.However,the increases of the loads and moments are effectively remitted using the optimized control methods of blade pitch fault followed by high-speed shaft brake and low-speed feathering.
