Optimum Redundancy of an Independent Power Supply System and Comparative Analysis of Its Solutions

Аннотация

This article discusses the issue of structural redundancy with reference to improving the reliability of independent power supply. The problem of optimum redundancy has been formulated, and its mathematical interpretation has been given. The sequence of solution steps is described. Precise and approximate methods of its solution are considered. Drawbacks of the most used methods are highlighted. A mathematical formulation of optimum redundancy is presented using the dynamic programming method as a tool for decreasing the amount of tested versions. The number of computations used in various methods is compared. The regions of application of precise and approximate solutions of optimum redundancy are defined taking into account design development phases.
