Abstract:

The aerodynamics characteristics of wind turbine were calculated by applying GDW theory and were programmed in MATLAB/Simulink. The drive chain was calculated by applying state space method and also programmed in MATLAB/Simulink. The model of the wind turbine was built in Adams. The simulation of vibration characteristics was carried out so that the aerodynamic loads and the torque were applied to the structure of the rotor. Simultaneously the deformation of the structure also affected the loads. The results show that the method has excellent ability to simulate the vibration characteristics almost the same as test measured.

Key words: GDW(generalized dynamic wake) theory, combined simulation, wind turbine, vibration

摘要：

采用通用动态尾流理论进行风力机气动力学的计算分析，并用MATLAB/Simulink进行编程，建立了风力机传动链的数学模型。在MATLAB/Simulink中进行传动链系统的编程运算，建立了风力机ADAMS柔性多体结构动力学仿真模型，并利用MATLAB/Simulink和ADAMS进行风力机振动性能的联合仿真。仿真时将气动载荷加载到风力机叶片结构上，将传动系统模型的反扭矩加到ADAMS风轮模型上，同时考虑风力机的结构变形对气动性能、传动性能产生的影响。仿真最终实现了风力机系统振动性能耦合分析，其数据同实验测试数据比较表明，该联合仿真方法可以较好地模拟风力机的振动特性。
