摘要：ABSTRACT: This paper presents an evaluation of Markov models used to obtain unit reliability and availability the operational data of Pathri and Chilla power stations (India) for period 2007 - 2012. The most important reliability indices are found namely failure rate (λ), repair rate (μ), MTTR, MTBF, MTTF Through data collection and analysis. The data of each year and for each unit is time scheduled. After tabulating all the data, we classified for each unit the different type of failure taking into account the various sub units and systems. According to the classification we defined Markov states. Failure rate repair rate of all state are found from the classified data. The determination of availability and reliability from their definition is completed.
