• RELIABILITY ANALYSIS OF A POWER DISTRIBUTION SYSTEM WITH ENVIRONMENTAL EFFECTS UNDER PREEMPTIVE RESUME REPAIR POLICY

Abstract

This paper deals with reliability analysis of a three state power distribution system consisting of two subsystems with environmental effects under preemptive resume repair policy. A mathematical model for a power distribution system under service restrictions has been developed for exponential failures and general repairs. Supplementary variable technique has been employed to obtain various state probabilities and then the operational availability is obtained by the inversion process. The study state behavior, reliability, MTTF and profit function have also been analyzed by some graphical illustrations to explain the practical utility of the model.
