Reliability based maintenance programming by a new index for electrical distribution system components ranking

Abstract Reliability and accessibility of distribution systems are important goals that have significant impacts on the costs. The proper strategy maintenance based components arrangement assets is best way to reach these goals. This a kind uses reliability-centered (RCM). Due limited budget, performing activities for all system neither possible nor logical. So most resources should be allocated critical components. paper presents novel analytical method prioritization systems’ by introducing new weighted cumulative Reliability-based diagnostic importance factor. factor includes different reliability indexes in form factors will show order obtained this better than another saving budget providing system. process decision-making their criticality degree both improve level total decrease cost load interruption finally proposed model implemented radial network. Numerical results effectiveness RCM micro-grids.
