Abstract:

In operation of the turbine generator, under the action of forces, the stator winding may vibrate; and the abnormal vibration of the end of the

winding will cause faults. The feasibility and the necessity of additional installation of optical fiber vibration monitoring system onto the turbine

generator were analyzed. The installation method of the optical fiber vibration measurement probe was described. After the optical fiber vibration

measurement system had been installed additionally onto the generator No.4 of Guangdong Zhuhai Jinwan Power Generation Company Limited, by means of manual

intervention, the vibration amplitude of the winding end was reduced effectively. 

Key words: turbine generator, stator winding, vibration, optical fiber acceleration transducer
