Abstract—The new generation of condition monitoring and diagnostics system plays an important role in efficient functioning of power plants. Most rotating machine defects can be detected by such a system much before a dangerous situation occurs. It allows the efficient use of stationary online continuous monitoring system for condition monitoring and diagnostics as well. Now a days real time monitoring reduces breakdowns to a large extent. We can conduct it with help of sensors and analyzers with software. T.S.I includes various velocity transducers, accelerometers and LVDT’s with suitable automation and software for proper human interaction. By the help of real time monitoring we can assure continuous power supply without any catastrophic failure. The object of this paper is to identify influence of lube oil temperature on turbine shaft vibration at turbo generator at unit-6 (195 MW), Kota super thermal power station by measuring vibration amplitude and analyzing problem with help of Matlab.

Index Terms—Lube oil temperature, Turbine shaft displacement, Axial shift, HPT, IPT, LPT
