摘　　要：本文基于台风平均风速理论模型以及功率密度谱,提出了一种能够生成具有台风特性三维湍流风场的方法,并编写了实现程序。最后以kaimal谱为例,将生成的湍流风与Bladed生成的湍流风做了频谱对比和载荷计算结果对比,验证了该方法的可靠性,为制定抗台风型风电机组设计标准提供了有效的工具。Based on typhoon average wind speed theory model and power density spectrum, this paper put forward a method which can generate three-dimensional turbulent wind field with typhoon characteristics, and write the realizing program . Finally, the kaimal spectrum was taken as an example, spectrum contrast and load calculation results were compared between turbulent wind and Bladed generated turbulent wind. It verified the reliability of this method and provided effective tools for setting anti-typhoon type wind turbines design standards.
