Abstract

Generator dynamic simulation physical was set up with SIMPACK multi-body dynamics software. Non-linear feature of bearing and the influence of elastic support on generator were researched. Results showed that the alteration of bearing stiffness would significantly change the natural frequency of the generator rotor, and may cause resonance with power grid. The variation of the elastic support stiffness would change the generator stand natural frequency.

风力机双馈感应发电机振动特性的理论与实验研究
利用SIMPACK多体动力学软件建立发电机动态仿真物理。研究了轴承的非线性特性和弹性支承对发电机的影响。结果表明,轴承刚度的改变会显著改变发电机转子的固有频率,并可能引起与电网的共振。弹性支承刚度的变化会改变发电机机架固有频率。
