摘要/Abstract

摘要： 为研究漂浮特性对风力发电机塔基载荷性能的影响,使用仿真技术进行分析。将漂浮平台和波浪载荷考虑到已建好的风力发电机组模型中,形成漂浮式风力发电机组分析模型。以NREL 5 MW数据为基础,利用FAST软件对漂浮式和基础固定式风电机组涉及的各典型工况进行载荷性能仿真,并将2种风电机组的仿真结果进行对比。研究结果表明：漂浮特性对风电机组塔基载荷的波动及极限载荷的影响显著,通过对比2种风电机组各典型工况下的仿真结果,得出漂浮式风电机组塔基极限载荷相比基础固定式机组结果呈现规律分布,并对规律分布的原因作出了分析。

Abstract: Simulation techniques are applied to study the impact of floating characteristics on tower base load performance. In this paper, the floating platform and the wave load are taken into account in the established wind turbine model to formulate the floating wind turbine model. Finally, by taking the NREL 5 MW baseline wind turbine, the performance of typical loads of floating wind turbine and fixed wind turbine are simulated by virtue of FAST software package and corresponding results are compared. The research outcome shows that the floating characteristics have significant impact on the load fluctuations as well as the load limits of tower base. The comparison between the typical conditions of the two kinds of wind turbines indicates that the distribution of limit loads of floating wind turbines is more regular than that of fixed wind turbines, and the cause of this regular distribution is also analyzed.

Key words: floating characteristic, wind turbine, wave load, tower base load
