基于Adams的MW级风力发电机组动力学建模

Dynamic model of MW grade wind turbine based on Adams

为了实现MW级风电发电机组仿真,根据其结构特征和各个运动机构的传动链关系,实现了将Solid-works中的三维几何模型转换为Adams中的动力学模型。在该模型中,根据偏航系统、齿轮箱和变桨系统的运动传递关系,施加了运动约束条件,在桨叶或轮毂上施加了风力产生的作用力矩,在转子制动器和偏航制动器上施加了制动力矩,在发电机上施加了负载。通过定义输入和输出参数,建立了Adams动力学模型与其他控制软件的接口,实现了风力发电机组由启动到稳定运行的全过程仿真,表明建立的仿真模型和方法是正确的、可行的。

In order to simulate the behavior of mechanical and controlling system of a MW grade wind turbine, according to the structure feature and transmission relation of the wind turbine, three dimension model based on Solidworks software was convened into dynamic model based on Adams software. In the dynamic model, the motion transmission relation of the yawing system, gear box and blade system was used as the motion constraint condition. Driving force or torque caused by wind was applied on the blade or hub. Braking force or torque was applied on rotor brake and yawing brake. Load was applied on generator. Measuring parameters used to measure angle, speed, acceleration, force, torque and so on were established. Inputting and outputting parameters used to realize the simulation were defined in order to establish the interface between Adams and controlling software. The process from stop to stable operating status was simulated, h is shown that the model and the method used to simulate the behavior of the wind turbine are correct.
