【摘要】 脉动风速模型主要反映脉动风速的位置分布和时间变化特性,其对整个风力发电机组与电网的运行状态有重要影响,是风力发电仿真研究的基础。文中根据风力发电机的结构特点与脉动风的特性,利用自回归法建立了具有一定功率谱密度特性的脉动风速模型,利用Matlab进行了仿真模拟。仿真结果表明:在工程精度范围内,文中风速模型较好地反映了脉动风的特性,满足了工程应用要求。更多还原

【Abstract】 Turbulent wind model mainly reflects the distribution and variation characteristic of turbulent wind speed,so it greatly impacts the operation of both wind power generation units and power network and is the foundation for simulative research of wind power generation.According to the structural features and the characteristic of turbulent wind,by use of autoregression a turbulent wind speed model with a certain power spectral density is built and simulated by Matlab software.Simulation results show that within the engineering precision range the proposed wind speed model can reflect the characteristic of turbulent wind.更多还原
