Reliability Analysis of CHU System of Coal Fired Thermal Power Plant Using Fuzzy λ-τ Approach

AbstractThe aim of this research work is to study the behaviour of the CHU (compressor house unit) of a medium size coal fired thermal power plant using fuzzy λ-τ approach (quantitative approach). The system has been modelled using PN and various reliability indices viz. failure rate, repair time, MTBF, ENOF, Availability and reliability are computed at different spread/uncertainty level. The results are helpful to the system analyst to analyse the behaviour of the system and to plan suitable maintenance policy for improving the system availability
