Neeraj Gochar, Dharmendra Kumar Jain

Abstract: Super Thermal Power Stations (STPS) or Super Power Station are a series of ambitious power projects planned by the Government of India. With India being a country of chronic power deficits, the Government of India has planned to provide 'power for all' by the end of the plan, The capacity of thermal power is 1000 MW and above. This paper presents an analysis of steam turbine vibration monitoring system of kota super thermal power plant. In this paper, a detailed concept and techniques used in turbine vibration monitoring, monitoring equipments and vibration analysis of turbo generator of 195 MW, UNIT-7 has been discussed to evaluate performance of turbine. A detailed report on vibrations of bearings corresponding to the bearing temperatures of turbo generator has been done by using IRD 880 instruments.
