摘要

摘要: 准确构建湍流风速模型对风力机全系统仿真、平稳功率控制、系统动态特性、控制系统设计等方面至关重要。针对湍流发生实时性不强的问题,提出了应用于实时仿真的湍流谱滤波器的设计方法,将高斯白噪声通过所设计的湍流谱滤波器能够获得实时仿真湍流风速,仿真分析表明湍流滤波器能够应用于实时湍流风速的产生。同时,提出了融合风切变、塔影效应、湍流和旋转采样的等效风速实现方法,并在仿真软件中建立了等效风速发生系统。通过对某实际湍流风速仿真分析表明,基于所设计的湍流滤波器的等效风速发生系统是有效可行的。

Abstract: Precisely constructing turbulence wind model avails the whole system simulation, stable power control, system dynamics analysis and control system design of wind turbine. In order to solve weak real-time characters of ＂ turbulence generating, a design method of turbulence filter based real-time simulation is proposed in this paper. The real time turbulence wind can be acquired when Gaussian white noise goes through the designed turbulence fiter. The equivalent wind speed combining wind shear, tower shadow effect, turbulence and rotational sampling has been realized in software. The simulation results show that the generating system of equivalent wind speed based turbulence filter is practicable and effective.
