SENSITIVITY OF RELIABILITY INDICATOR FOR THE GAS TURBINE COGENERATION POWER PLANT.

This paper proposes an analysis procedure for a gas turbine cogeneration power plant (CHP) from the point of view of the sensitivity of the reliability indicator. The relevant indicators for the reliability of a CHP are considered to be the yearly mean time to failure and the sensitivity of the yearly mean time to failure. The reliability indicators are calculated based on an exponential distribution for the uninterrupted operation duration and for the failure duration. A block diagram is created for determining the reliability of the CHP subcomponents based on the thermo-mechanical diagram. The exception to the block diagram calculation method is the electrical subsystem which uses the binomial method. The reliability indicators of the block diagram components come from standards or literature. An application for a CHP is presented. [ABSTRACT FROM AUTHOR]
