Kou Sheng

Abstract

Diagnosis procedure of severe vibration in two 100MW steam-turbine generator sets in Zhunneng power plant is introduced in this paper. The causes are components block in LP rotor of No.1 set and entrance of high temperature steam in LP case of No.2 set. .In this paper the vibration characteristics and diagnosis are introduced.
