Abstract :
A new methodology for the evaluation of nonfailure operating time (NFOT) in the virtual test bed (VTB) environment is proposed. The proposed method is featured by the application of time-frequency analysis to estimate the parameters of reliability at the earliest stages of design based on the intercoupling of the 1/f noise and the reliability of power system elements. The proposed approach enables one to directly quantify the reliability of the system by the investigation of the physical properties of the nonequilibrium fluctuations.
