摘要
本文对国内生产的引进型1000MW汽轮发电机定子绕组端部模态进行了深入的研究,对其运行效果进行了广泛的调研,结合在线振动装置数据提出了新问题,即虽然端部模态不符合国标GB/T 20140-2006《透平型发电机定子绕组端部动态特性和振动试验方法及评定》要求,但也能安全运行的结论及修订GB/T20140-2006的必要性。
With intensive analysis, operation investigation and on-line vibration data for stator end-winding of introduction 1000MW turbo-generator, we can draw a conclusion that these turbo-generators can operate safely even if the end-winding models couldn＇t conform to national standards GB/T 20140-2006 so that the amendment of standards is necessary.
