发电机转子在不对称运行下固有频率分裂规律的研究
摘要
发电机转子是一个水平刚度和垂直刚度基本相同的柔性体
转子的固有频率与转子本身有关
但当发电机的外接负载不对称时
转子的固有频率还与三相负载的不对称度有关
并且固有频率随激励电流变化而产生了奇特的分裂现象。
Abstract
The generator rotor is a flexible body with approximately equal horizontal and perpendicular stiffness. The natural frequency of the rotor is related to rotor itself
but it is also related to the degree of unsymmetry of load when the load of generator is unsymmetric. And we also found that the natural frequency appeared separating phenomenon with the changes of inciting currency.
