光学振动监测系统在发电机在线监测方面的应用与实践

Application and Practice on Optical Vibration Monitoring System for Generator Online Monitoring

发电机定子绕组端部在线振动监测是保证发电机安全运行的重要措施,具有很高的技术难度。本文介绍了光学振动测量系统在发电机定子绕组端部振动在线监测方面的发展现状,以及在一台国产200MW汽轮发电机上的实践应用结果。

Online vibration monitoring of end of stator winding is the important measure for safe operation of generator. Because of the bad electromagnetic environment inside of generator, it is difficult technically to carry out the online vibration monitoring of end of stator winding. This paper introduces the present situation of development about optical vibration measure system for online vibration monitoring of end of stator winding, as well as the results of application and practice on a home made turbine generator of 200 MW.
