摘要
对４台３００ＭＷ汽轮发电机的定子绕组做了固有频率测试，并进行了说明，包括测试分析的基本原理、测试仪器简介、测试实例、处理方法等，并对固有频率的范围规定做了讨论。
The natural frequencies for stator windings of four 300MW turbogenerators are sured individually.The measuring principle and instrument are described.Several cases and thecorresponding treatment are presented in this paper. Speification for the range of natural frequen-cy is discussed.
