1000MW发电机转子三阶振型的现场非正交平衡

摘要

Un-orthogonal method is applied to field balance the third modal vibration in one 1 000MW capacity generatorrnrotor and the vibration amplitude is deduced to satisfied level. This method is proved useful to eliminate this type vibrationrnproblems.%基于发电机转子现场动平衡可利用的加重位置的实际情况考虑,采用非正交加重的非常规现场动平衡方法消除发电机转子的三阶振型,将振幅控制在优良水平.结果证明所采用的方法是正确的、有效的.
