Abstract

Abstract: The vibration of steam turbine-generator set is common fault. It is very important for safety and economic operation of turbine-generator set that to deeply study the mechanism of vibration occurrence and development, to diagnose the fault correctly and to propose treatment measures timely. There was abnormal vibration occurred in a 210MW steam turbine-generator set of a corporation at low speed, and the set could not start-up normally. It is believed by analysis of the set status that the main reason caused the larger vibration of the set is the rotor mass no balanced. After treatment, the both of bush vibration and axis vibration were reduced to the ideal target.

Key words: steam turbine-generator set, abnormal vibration, Failure analysis, treatment, test
