Reliability Availability and Sensitivity Analysis of a Power distribution System

This paper presents a reliability and availability analysis of a power distribution system comprising transformers, aiming to obtain reliability indices that reflect the overall system's operational capabilities. It investigates causes of power unavailability, such as severe weather and electrical faults. Results demonstrate the impact of environmental conditions and electrical faults on transformer reliability, with sensitivity analysis revealing how variations in failure and repair rates affect overall system reliability. The analysis utilizes five years of data from a power distribution system. The findings offer insights for enhancing power distribution system robustness and suggest future research directions to address reliability challenges, contributing to more resilient power infrastructure.
