Reliability Analysis of the Space Station Freedom Electrical Power System
Abstract
The on-board electrical power system of a space station has to provide the power needed for scientific missions (discretionary loads) and everyday station housekeeping chores (non-discretionary loads). Due to size constraints of the spacecraft, the electrical power system's output, efficiency and reliability will be constrained producing a system that is imperfect. This thesis applies traditional reliability techniques and modified methods to evaluate the reliability of the proposed NASA Space Station electrical power system. The modified methods take into account components and assemblies that have different levels of failure affecting the power output. These components and assemblies with failure levels other than 'all or nothing' power outputs define each power output level between complete outputs define each power output level between complete failure and expected nominal power. By applying this analysis approach to the proposed space station electrical power system in conjunction with some reasonable assumptions, different levels of the electrical power output are identified along with the exceedance probability that each interval will occur at a specified time.
