ABSTRACT

The thermal power plant is a primary source of power generation in India. It is a big challenge to maintain the failure-free operation of a thermal power plant. The availability of a coal-based thermal power plant depends upon reliability and maintainability of equipment/system used. Therefore, to operate the plant with full capacity, the condition monitoring techniques play a significant role in detecting and diagnosing the fault of the equipment/system before any sudden failure or breakdown. The condition monitoring based fault diagnosis facilitates the maintenance personnel to decide/modify the maintenance strategy of the plant. The current health of the system can be known more precisely by monitoring the parameters such as vibrations, noise level, and size of wear particle in the oil sample. The purpose of this study is to review the use of condition monitoring techniques and its application in thermal power plant for fault detection, fault identification, and fault classification of machinery through a survey of published literature. The present work reported reliability analysis of critical equipment of thermal power plant, which demands further improvement. The challenging areas and approaches of condition monitoring for fault diagnosis of the system used in the thermal power plant are presented in the study.
