摘要
在整机基础支撑结构的设计开发过程中,了解波浪载荷对海上风力发电机组疲劳载荷的影响至关重要.该文选取中国沿海地区部分典型海上风电场址,通过波浪凝聚及JONSWAP谱,对所选典型场址的波浪水文条件进行分析处理,并以此为变量,仿真研究不同波浪对于海上风力发电机组关键部件的疲劳载荷影响.最后,引入风浪异向,更贴合实际地评估波浪对疲劳载荷的影响.
Abstract
In the design and development process of the base support structure of the whole turbines,it is very important to understand the influence of wave loads on the fatigue load of offshore wind turbines.This paper selects some typical offshore wind farm sites in coastal areas of China,and analyzes the processes the wave hydrological conditions of each site through wave condensation and JONSWAP spectrum,and uses this as a variable to simulate the fatigue load of different waves on key components of offshore wind turbines.Finally,wind and wave misalignmentis introduced to evaluate the effect of waves on fatigue loads more realistically.
