The purpose of this paper is to analyze a thermal power plant (TPP) by taking into consideration its key components, namely, boiler, turbine, conveyor and generator, which are handled by a human operator. It is well known fact that the continuous power generation through a power plant depends on the reliability/availability of its components.


The various performance measures of a TPP are obtained by using mathematical modeling, Markov process and supplementary variable technique.


Reliability, i.e. mean time to failure with respect to different components of a TPP, has been obtained and demonstrated with the help of graphs. Critical components of the system are identified through sensitivity analysis.


In the present paper, a mathematical model based on the functioning of a TPP has been developed. Conclusions in this paper are good references for the design of a TPP.



This research did not receive any specific grant from funding agencies in the public, commercial or not-for-profit sectors. The author is thankful to the reviewers for their valuable suggestions for the improvement of the paper.
