Analysis of production downtimes in thermal power plant using exponential failure model – A case study

Now a day's Karnataka State is witnessing electricity load shedding due to various reasons among which, technical problems play vital role. These technical problems lead to failure of equipments like Boiler, Furnace and so on, leading to the electricity load shedding. Smoother flow of electricity generation is very essential to reduce the electricity load shedding. For this it is required to understand and analyze the failure patterns or production downtimes in a systematic manner.

Thus in this paper, we have developed a model based on failure patterns of seven thermal power units located at Shaktinagar, Raichur., Karnataka. For the collected data, Exponential Model is fitted and tested for its Goodness of Fit. Based on the fitted model we have estimated reliabilities of thermal power units. Conclusions were drawn based on the result obtained.
