Integrated Treatment for Vibration of Domestic 600 MW Turbo-Generator Units in Zhejiang Province

The domestic 600 MW turbo-generator units are dominant in Zhejiang power grid.The safe operation is directly related to the stability of power grid,and the vibration is among the most important parameters that affect the safe operation of units.This paper summarizes the typical vibration problems including quality imbalance,weak rigidity of low-pressure cylinder,static and dynamic friction,rotating part falloff,inadequate centering,unstable vibration of exciter and short circuit between the windings of generator based on the solutions to the problems of twenty 600 MW domestic turbo-generator units and offers a reference for other units of the same type.
