【摘要】 采用仿真软件TurbSim建立紊流风场数据、AeroDyn建立气动力数据、FAST(fatigue,aerodynamics,structures,andturbulence)建立风力发电机组动力学模型,并将三者联合起来,建立完整的风力发电机组系统动力学模型。通过多叶片坐标变换(multi-blade coordinate)将系统动力学模型中与叶片相关的转动自由度转换到固定坐标系中,并进行稳定性分析。以某600 kW失速型风力机为例,根据联合仿真得到该风力机在稳态和紊流风场下的叶尖、塔架的变形和轮毂叶根处的受力,并得到不考虑气动力情况下的风力机系统稳定性结果。更多还原

【Abstract】 After the stochastic inflow turbulence,the aerodynamcs and the wind turbine’s structural dynamic model constructed by simulation softwares of TurbSim,AeroDyn and FAST(fatigue,aerodynamics,structures,and turbulence) respectively,the full dynamic model of wind turbine system has been setup.The DOFs(degree of freedom) related to rotating blades have been transformed into stationary reference frame by using multi-blade coordinate transformation,then stability analysis has been conducted.The deformations of blades and tower top have been generated in steady and turbulence wind field for a 600 kW stall-regulated wind turbine and the results of stability analysis at different rotor speed without aerodynamic has been gerenated,and the Coleman diagram ploted according to them.更多还原
