Method of Setting Reliability Requirements for a Power Supply System

The article describes a method of setting the requirements for reliability of a power supply system, which could be applied in the context of limited source data. This work considers questions of reliability apportionment between systems of a facility with the view to set the requirements for reliability of a power supply system. The study evaluates possibility of application of source data based on a priori reliability indexes of comparables in order to apportion the requirements. The study describes main stages of significance estimation of the systems of a facility using functional topological method that was adjusted by the authors to be applied to any complex system consisting of nonhomogeneous components. The article presents mathematical models of reliability apportionment that define requirements depending on level of significance of facility systems with regard to the probability function of reliability of the facility.
