摘要
在前期研究工作的基础上,将浮式基础波浪载荷计算和系泊系统计算考虑到所已建立的风力发电机分析模型中,形成漂浮式风力发电机性能分析模型,将其在风浪下进行漂浮式风力发电机的载荷分析计算。结果表明:漂浮式平台对风力发电机的载荷影响很大,同样条件下漂浮式风力发电机所受载荷相对固定式风力发电机幅值变化较大(平均值一样),这意味着漂浮式风机的疲劳寿命会有较大下降,因此,针对固定风机的设计方法对漂浮式风机要有所修正及完善。
In this paper,the floating wind turbine system was researched based on former study.The sea environmental load analysis model and mooring system were established,based on which system performance analysis was researched.Studies have shown that:floating platform has great influence on the performance of wind turbine,under the same conditions suffered by floating wind turbine and fixed wind turbine,performance on floating turbine changes in amplitude relatively large,which means reduction in power quality for floating wind turbine,therefore,the design method for the float wind turbine should be revised and improved.
