دانلود مقاله INCORPORATING RELIABILITY AND FAILURE MODELS INTO ENERGY SYSTEM ANALYSIS سال 2014

ABSTRACT Estimation of the mean lifetime and reliability of sophisticated systems such as cogeneration power plant (CHP) is a challenging problem in energy-engineering applications. A simulation model that predicts failure and repair times is described and used to calculate operating time availability and costs to operate the system. The new concept of estimated repair time with a Weibull probability density function is the key to the study of the down time. This probability distribution was de ...
